       This man page documents lftp version 4.7.0.

       lftp  is a file transfer program that allows sophisticated FTP, HTTP and other connections to
       other hosts. If site is specified then lftp will connect to that site otherwise a  connection
       has to be established with the open command.

       lftp  can  handle  several file access methods - FTP, FTPS, HTTP, HTTPS, HFTP, FISH, SFTP and
       file (HTTPS and FTPS are only available when  lftp  is  compiled  with  GNU  TLS  or  OpenSSL
       library).   You   can   specify  the  method  to  use  in  `open  URL'  command,  e.g.  `open
       http://www.us.kernel.org/pub/linux'. HFTP is ftp-over-http-proxy protocol.  It  can  be  used
       automatically instead of FTP if ftp:proxy is set to `http://proxy[:port]'. Fish is a protocol
       working over an ssh connection to a unix account. SFtp is a protocol implemented in  SSH2  as
       SFTP subsystem.

       Besides  FTP-like  protocols,  lftp has support for BitTorrent protocol as `torrent' command.
       Seeding is also supported.

       Every operation in lftp is reliable, that is any non-fatal error is handled properly and  the
       operation is repeated. So if downloading breaks, it will be restarted from the point automat‐
       ically. Even if FTP server does not support the REST command, lftp will try to  retrieve  the
       file from the very beginning until the file is transferred completely.

       lftp  has  shell-like  command  syntax allowing you to launch several commands in parallel in
       background (&). It is also possible to group commands within () and  execute  them  in  back‐
       ground.  All  background  jobs are executed in the same single process. You can bring a fore‐
       ground job to background with ^Z (c-z) and back with command `wait' (or `fg' which  is  alias
       to  `wait').  To list running jobs, use command `jobs'. Some commands allow redirecting their
       output (cat, ls, ...) to file or via pipe to external command. Commands can be executed  con‐
       ditionally based on termination status of previous command (&&, ||).

       If you exit lftp before all jobs are not finished yet, lftp will move itself to nohup mode in
       background. The same thing happens with a real modem hangup or when you close an xterm.

       lftp has built-in mirror which can download or update a whole directory tree. There  is  also
       reverse  mirror  (mirror  -R) which uploads or updates a directory tree on server. Mirror can
       also synchronize directories between two remote servers, using FXP if available.

       There is command `at' to launch a job at specified time in current context,  command  `queue'
       to queue commands for sequential execution for current server, and much more.

       On  startup,  lftp  executes  /etc/lftp.conf  and  then  ~/.lftprc and ~/.lftp/rc (or ~/.con‐
       fig/lftp/rc if ~/.lftp does not exist).  You can place aliases and `set' commands there. Some
       people  prefer to see full protocol debug, use `debug' to turn the debug on. Use `debug 3' to
       see only greeting messages and error messages.

       lftp has a number of settable variables. You can use `set -a' to see all variables and  their
       values or `set -d' to see list of defaults.  Variable names can be abbreviated and prefix can
       be omitted unless the rest becomes ambiguous.

       If lftp was compiled with OpenSSL (configure --with-openssl) it includes  software  developed
       by the OpenSSL Project for use in the OpenSSL Toolkit. (http://www.openssl.org/)

       ! shell command

       Launch shell or shell command.


       To do a directory listing of the local host.

       alias  [name [value]]

       Define or undefine alias name. If value is omitted, the alias is undefined, else it takes the
       value value. If no argument is given the current aliases are listed.

            alias dir ls -lF
            alias less zmore

       at time [ -- command ]

       Wait until the given time and execute given (optional) command. See also at(1).

       attach  [PID]

       Attach the terminal to specified backgrounded lftp process.

       bookmark  [subcommand]

       The bookmark command controls bookmarks.

       Site names can be used in the open command directly as-is or  in  any  command  that  accepts
       input URLs using the bm:site/path format.

            add <name> [<loc>]   add  current place or given location to bookmarks and bind to given
            del <name>           remove bookmark with name
            edit                 start editor on bookmarks file
            import <type>        import foreign bookmarks
            list                 list bookmarks (default)

       cache  [subcommand]

       The cache command controls local memory cache.  The following subcommands are recognized:

            stat        print cache status (default)
            on|off      turn on/off caching
            flush       flush cache
            size lim    set memory limit, -1 means unlimited
            expire Nx   set cache expiration time to N seconds (x=s) minutes (x=m)  hours  (x=h)  or
                        days (x=d)

       cat files

       cat outputs the remote file(s) to stdout.  (See also more, zcat and zmore)

       cd rdir

       Change  current remote directory.  The previous remote directory is stored as `-'. You can do
       `cd -' to change the directory back.  The previous directory for each site is also stored  on
       disk, so you can do `open site; cd -' even after lftp restart.

       chmod mode files

       Change permission mask on remote files. The mode must be an octal number.

       close [-a]

       Close  idle  connections.   By default only with the current server, use -a to close all idle

       cls [OPTS] files...

       `cls' tries to retrieve information about specified files  or  directories  and  outputs  the
       information  according  to format options. The difference between `ls' and `cls' is that `ls'
       requests the server to format file listing, and `cls' formats it itself, after retrieving all
       the needed information.

            -1                         single-column output
            -a, --all                  show dot files

            -h, --human-readable       print sizes in human readable format (e.g., 1K)
                --si                   likewise, but use powers of 1000 not 1024
            -k, --kilobytes            like --block-size=1024
            -l, --long                 use a long listing format
            -q, --quiet                don't show status
            -s, --size                 print size of each file
                --filesize             if printing size, only print size for files
            -i, --nocase               case-insensitive pattern matching
            -I, --sortnocase           sort names case-insensitively
            -D, --dirsfirst            list directories first
                --sort=OPT             "name", "size", "date"
            -S                         sort by file size
                --user, --group,
                --perms, --date,
                --linkcount, --links   show individual fields
                --time-style=STYLE     use specified time format

       command cmd args...

       execute given command ignoring aliases.

       debug [OPTS] level|off

       Switch debugging to level or turn it off. Options:

            -o <file> redirect debug output to the file
            -c        show message context
            -p        show PID
            -t        show timestamps

       echo [-n] string

       Prints (echos) the given string to the display.

       edit [OPTS] file

       Retrieve  remote  file  to a temporary location, run a local editor on it and upload the file
       back if changed. Options:

            -k        keep the temporary file
            -o <temp> explicit temporary file location

       eval [-f format ] args...

       without -f it executes given arguments as a command. With -f, arguments are transformed  into
       a new command. The format can contain plain text and placeholders $0...$9 and $@, correspond‐
       ing to the arguments.

       exit [bg] [top] [parent] [kill] [code]

       exit will exit from lftp or move to background if there are active jobs. If no job is active,
       code is passed to operating system as lftp's termination status. If code is omitted, the exit
       code of last command is used.

       `exit bg' forces moving to background when cmd:move-background is false.   `exit  top'  makes
       top  level  `shell' (internal lftp command executor) terminate.  `exit parent' terminates the
       parent shell when running a nested script.  `exit kill' kills all numbered jobs before  exit‐
       ing.  The  options  can  be  combined, e.g.  `at 08:00 -- exit top kill &' kills all jobs and
       makes lftp exit at specified time.


       Alias for `wait'.

       find [OPTS] directory...

       List files in the directory (current directory by default) recursively.  This can  help  with
       servers lacking ls -R support. You can redirect output of this command. Options:

            -d MD, --max-depth=MD   specify maximum scan depth
            -l,    --list           use long listing format


       Obsolete. Use one of the following instead:
            get ftp://... -o ftp://...
            get -O ftp://... file1 file2...
            put ftp://...
            mput ftp://.../*
            mget -O ftp://... ftp://.../*
       or  other  combinations  to  get FXP transfer (directly between two FTP servers).  lftp would
       fallback to plain copy (via client) if FXP transfer cannot be  initiated  or  ftp:use-fxp  is

       get [-E] [-a] [-c] [-e] [-O base] rfile [-o lfile] ...

       Retrieve  the  remote file rfile and store it as the local file lfile.  If -o is omitted, the
       file is stored to local file named as base name of rfile. You can get multiple files by spec‐
       ifying  multiple  instances  of rfile (and -o lfile). Does not expand wildcards, use mget for

            -c          continue, reget
            -E          delete source files after successful transfer
            -e          delete target file before the transfer
            -a          use ascii mode (binary is the default)
            -O <base>   specifies base directory or URL where files should be placed

            get README
            get README -o debian.README
            get README README.mirrors
            get README -o debian.README README.mirrors -o debian.mirrors
            get README -o ftp://some.host.org/debian.README
            get README -o ftp://some.host.org/debian-dir/   (end slash is important)

       get1 [OPTS] rfile

       Transfer a single file. Options:

            -o <lfile>                  destination file name (default - basename of rfile)
            -c                          continue, reget
            -E                          delete source files after successful transfer
            -a                          use ascii mode (binary is the default)
            --source-region=<from-to>   transfer specified region of source file
            --target-position=<pos>     position in target file to write data at

       glob  [OPTS] [command] patterns

       Glob given patterns containing metacharacters and pass result  to  given  command  or  return
       appropriate exit code.

            -f            plain files (default)
            -d            directories
            -a            all types
            --exist       return zero exit code when the patterns expand to non-empty list
            --not-exist   return zero exit code when the patterns expand to an empty list

            glob echo *
            glob --exist *.csv && echo "There are *.csv files"

       help [cmd]

       Print help for cmd or if no cmd was specified print a list of available commands.

       jobs [OPTS] [job_no...]

       List running jobs. If job_no is specified, only list a job with that number.  Options:

            -v   verbose, several -v increase verbosity
            -r   list just one specified job without recursion

       kill all|job_no

       Delete specified job with job_no or all jobs.  (For job_no see jobs)

       lcd ldir

       Change  current  local directory ldir. The previous local directory is stored as `-'. You can
       do `lcd -' to change the directory back.

            local mirror /dir1 /dir2


       Print current working directory on local machine.

       ls params

       List remote files. You can redirect output of this command to file or via  pipe  to  external
       command.  By default, ls output is cached, to see new listing use rels or cache flush.

       mget [-c] [-d] [-a] [-E] [-O base] files

       Gets selected files with expanded wildcards.

            -c          continue, reget.
            -d          create  directories  the  same  as  file  names  and get the files into them

       mirror [OPTS] [source [target]]

       Mirror specified source directory to local target directory. If  the  target  directory  ends
       with  a  slash  (except the root), the source base name is appended to target directory name.

       When  using -R, the source directory is local and the target is remote.  If the target direc‐
       tory is omitted, base name of the source directory is used.  If both directories are omitted,
       current  local  and  remote  directories are used.  If the target directory ends with a slash
       (except the root directory) then base name of the source directory is appended.

       RX is an extended regular expression, just like in egrep(1).

       GP is a glob pattern, e.g. `*.zip'.

       Include and exclude options can be specified multiple times. It means that a file  or  direc‐
       tory  would  be  mirrored  if  it matches an include and does not match to excludes after the
       include, or does not match anything and the first check is exclude. Directories  are  matched
       with a slash appended.

       Note  that symbolic links are not created when uploading to remote server, because FTP proto‐
       col cannot do it. To upload files the links refer to, use `mirror -RL'  command  (treat  sym‐
       bolic links as files).

       For options --newer-than and --older-than you can either specify a file or time specification
       like that used by at(1) command, e.g.  `now-7days' or `week ago'. If you specify a file, then
       modification time of that file will be used.

       Verbosity  level  can be selected using --verbose=level option or by several -v options, e.g.
       -vvv. Levels are:
            0 - no output (default)
            1 - print actions
            2 - +print not deleted file names (when -e is not specified)
            3 - +print directory names which are mirrored

       --only-newer turns off file size comparison and uploads/downloads only newer  files  even  if
       size is different. By default older files are transferred and replace newer ones.

       --upload-older  allows  replacing newer remote files with older ones (when the target side is
       remote). Some remote back-ends cannot preserve timestamps so the default  is  to  keep  newer

       Recursion  mode  can be one of `always', `never', `missing', `newer'. With the option `newer'
       mirror compares timestamps of directories and enters a directory only if it is older or miss‐
       ing  on  the  target side. Be aware that when a file changes the directory timestamp may stay
       the same, so mirror won't process that directory.

       You can mirror between two servers if you specify URLs instead of directories.  FXP is  auto‐
       matically used for transfers between FTP servers, if possible.

       Some  FTP  servers  hide  dot-files by default (e.g. .htaccess), and show them only when LIST
       command is used with -a option. In such case try to use `set ftp:list-options -a'.

       mkdir [-p] [-f] dir(s)

       Make remote directories. If -p is used, make all components of paths.  The  -f  option  makes
       mkdir quiet and suppresses messages.

       module module [ args ]

       Load  given  module  using dlopen(3) function. If module name does not contain a slash, it is
       searched in directories specified by module:path variable.   Arguments  are  passed  to  mod‐
       ule_init function. See README.modules for technical details.

       more files

       Same  as  `cat files | more'. if PAGER is set, it is used as filter.  (See also cat, zcat and

       mput [-c] [-d] [-a] [-E] [-O base] files

       Upload files with wildcard expansion. By default it uses the  base  name  of  local  name  as
       remote one. This can be changed by `-d' option.

            -c          continue, reput
            -d          create  directories  the  same  as in file names and put the files into them
                        instead of current directory
            -E          delete source files after successful transfer (dangerous)
            -a          use ascii mode (binary is the default)
            -O <base>   specifies base directory or URL where files should be placed

       mrm file(s)

       Same as `glob rm'. Removes specified file(s) with wildcard expansion.

       mv file1 file2

       Rename file1 to file2.

       nlist [args]

       List remote file names

       open [OPTS] site

       Select a server by host name, URL or bookmark. When an URL or bookmark  is  given,  automati‐
       cally change the current working directory to the directory of the URL.  Options:

            -e cmd            execute the command just after selecting the server
            -u user[,pass]    use the user/password for authentication
            -p port           use the port for connection
            -s slot           assign the connection to this slot
            -d                enable debug
            -B                don't look up bookmarks
            --user user       use the user for authentication
            --password pass   use the password for authentication
            --env-password    take password from LFTP_PASSWORD environment variable
            site              host name, URL or bookmark name

       pget [OPTS] rfile [-o lfile]

       Gets  the specified file using several connections. This can speed up transfer, but loads the
       net and server heavily impacting other users. Use only if you really  have  to  transfer  the
       file ASAP.  Options:

            -c           continue transfer. Requires lfile.lftp-pget-status file.
            -n maxconn   set  maximum  number  of  connections (default is taken from pget:default-n

       put [-E] [-a] [-c] [-O base] lfile [-o rfile]

       Upload lfile with remote name rfile. If -o omitted, the base name of lfile is used as  remote
       name. Does not expand wildcards, use mput for that.

            -o <rfile>   specifies remote file name (default - basename of lfile)
            -c           continue, reput. It requires permission to overwrite remote files
            -E           delete source files after successful transfer (dangerous)
            -a           use ascii mode (binary is the default)
            -O <base>    specifies base directory or URL where files should be placed

       pwd [-p]

       Print current remote URL. Use `-p' option to show password in the URL.

       queue [-n num ] cmd

       Add  the  given  command to queue for sequential execution. Each site has its own queue. `-n'
       adds the command before the given item in the queue. Don't try to queue `cd'  or  `lcd'  com‐
       mands,  it may confuse lftp. Instead do the cd/lcd before `queue' command, and it will remem‐
       ber the place in which the command is to be done. It is possible to queue up an already  run‐
       ning  job  by `queue wait <jobno>', but the job will continue execution even if it is not the
       first in queue.

       `queue stop' will stop the queue, it will not execute any new commands, but  already  running
       jobs  will continue to run. You can use `queue stop' to create an empty stopped queue. `queue
       start' will resume queue execution.  When you exit lftp, it will  start  all  stopped  queues

       `queue' with no arguments will either create a stopped queue or print queue status.

       queue --delete|-d [index or wildcard expression]

       Delete one or more items from the queue. If no argument is given, the last entry in the queue
       is deleted.

       queue --move|-m <index or wildcard expression> [index]

       Move the given items before the given queue index, or to the end if no destination is given.

            -q   Be quiet.
            -v   Be verbose.
            -Q   Output in a format that can be used to re-queue. Useful with --delete.

            > get file &
            [1] get file
            > queue wait 1
            > queue get another_file
            > cd a_directory
            > queue get yet_another_file

            queue -d 3             Delete the third item in the queue.
            queue -m 6 4           Move the sixth item in the queue before the fourth.
            queue -m "get*zip" 1   Move all commands matching "get*zip"  to  the  beginning  of  the
                                   queue.  (The order of the items is preserved.)
            queue -d "get*zip"     Delete all commands matching "get*zip".

       quote cmd

       For  FTP  -  send the command uninterpreted. Use with caution - it can lead to unknown remote
       state and thus will cause reconnect. You cannot be sure  that  any  change  of  remote  state
       because of quoted command is solid - it can be reset by reconnect at any time.

       For  HTTP  -  specific  to HTTP action. Syntax: ``quote <command> [<args>]''.  Command may be
       ``set-cookie'' or ``post''.
            open http://www.site.net
            quote set-cookie "variable=value; othervar=othervalue"
            set http:post-content-type application/x-www-form-urlencoded
            quote post /cgi-bin/script.cgi "var=value&othervar=othervalue" > local_file

       For FISH - send the command uninterpreted. This can be used to execute arbitrary commands  on
       server.  The  command must not take input or print ### at new line beginning. If it does, the
       protocol will become out of sync.
            open fish://server
            quote find -name \*.zip

       reget rfile [-o lfile]

       Same as `get -c'.

       rels [args]

       Same as `ls', but ignores the cache.

       renlist [args]

       Same as `nlist', but ignores the cache.

       repeat [OPTS] [[-d] delay] [command]

       Repeat specified command with a delay between  iterations.   Default  delay  is  one  second,
       default command is empty.

            -c <count>    maximum number of iterations
            -d <delay>    delay between iterations
            --while-ok    stop when command exits with non-zero code
            --until-ok    stop when command exits with zero code
            --weak        stop when lftp moves to background.

            repeat at tomorrow -- mirror
            repeat 1d mirror

       reput lfile [-o rfile]

       Same as `put -c'.

       rm [-r] [-f] files

       Remove remote files.  Does not expand wildcards, use mrm for that. -r is for recursive direc‐
       tory remove. Be careful, if something goes wrong you can lose files. -f suppress  error  mes‐

       rmdir dir(s)

       Remove remote directories.

       scache [session]

       List cached sessions or switch to specified session.

       set [var [val]]

       Set  variable to given value. If the value is omitted, unset the variable.  Variable name has
       format ``name/closure'', where closure can specify exact  application  of  the  setting.  See
       below  for details.  If set is called with no variable then only altered settings are listed.
       It can be changed by options:

            -a   list all settings, including default values
            -d   list only default values, not necessary current ones

       site site_cmd

       Execute site command site_cmd and output the result.  You can redirect its output.

       sleep interval

       Sleep given time interval and exit. Interval is in seconds by default, but  can  be  suffixed
       with 'm', 'h', 'd' for minutes, hours and days respectively.  See also at.

       slot [name]

       Select  specified slot or list all slots allocated. A slot is a connection to a server, some‐
       what like a virtual console. You can create multiple slots connected to different servers and
       switch between them. You can also use slot:name as a pseudo-URL evaluating to that slot loca‐

       Default readline binding allows quick switching between slots named 0-9 using Meta-0 - Meta-9
       keys (often you can use Alt instead of Meta).

       source file
       source -e command

       Execute commands recorded in file file or returned by specified external command.
            source ~/.lftp/rc
            source -e echo help


       Stop  lftp  process.  Note that transfers will be also stopped until you continue the process
       with shell's fg or bg commands.

       torrent [OPTS] torrent-files...

       Start BitTorrent process for the given torrent-files, which can be a local file, URL,  magnet
       link  or  plain  info_hash  written in hex or base32.  Local wildcards are expanded. Existing
       files are first validated unless --force-valid option is  given.  Missing  pieces  are  down‐
       loaded.  Files  are  stored  in  specified directory or current working directory by default.
       Seeding continues until ratio reachs torrent:stop-on-ratio setting or time  of  torrent:seed-
       max-time runs out.


            -O <directory>           specifies base directory where files should be placed
            --force-valid            skip file validation (if you are sure they are ok).
            --only-new               stop  if  the  metadata is known already or the torrent is com‐
            --only-incomplete        stop if the torrent is already complete.
            --dht-bootstrap=<node>   bootstrap DHT by sending  a  query  to  specified  node.   This
                                     option  should  be used just once to fill the local node cache.
                                     Port number may be given after colon, default  is  6881.   Here
                                     are   some  nodes  for  bootstrapping:  dht.transmissionbt.com,
                                     router.utorrent.com, router.bittorrent.com.
            --share                  share specified file or directory  using  BitTorrent  protocol.
                                     Magnet link is printed when it's ready.

       user user [pass]
       user URL [pass]

       Use  specified info for remote login. If you specify an URL with user name, the entered pass‐
       word will be cached so that future URL references can use it.


       Print lftp version.

       wait [jobno]
       wait all

       Wait for specified job to terminate. If jobno is omitted, wait for last backgrounded job.

       `wait all' waits for all jobs to terminate.

       zcat files

       Same as cat, but filter each file through zcat. (See also cat, more and zmore)

       zmore files

       Same as more, but filter each file through zcat. (See also cat, zcat and more)

       On startup, lftp executes ~/.lftprc and ~/.lftp/rc (or ~/.config/lftp/rc if ~/.lftp does  not
       exist).   You can place aliases and `set' commands there. Some people prefer to see full pro‐
       tocol debug, use `debug' to turn the debug on.

       There is also a system-wide startup file in /etc/lftp.conf.  It can be  in  different  direc‐
       tory, see FILES section.

       lftp has the following settable variables (you can also use `set -a' to see all variables and
       their values):

       bmk:save-passwords (boolean)
              save plain text passwords in  ~/.local/share/lftp/bookmarks  or  ~/.lftp/bookmarks  on

       cmd:at-queue-finish (string)
              the commands in string are executed once when all jobs in a queue are done.

       cmd:cls-completion-default (string)
              default cls options for displaying completion choices. For example, to make completion
              listings show file sizes, set cmd:cls-completion-default to `-s'.

       cmd:cls-default (string)
              default cls command options. They can be overridden by explicitly given options.

       cmd:cls-exact-time (boolean)
              when  true,  cls  would  try to get exact file modification time even if it means more
              requests to the server.

       cmd:csh-history (boolean)
              enables csh-like history expansion.

       cmd:default-protocol (string)
              The value is used when `open' is used with just host name without protocol. Default is

       cmd:fail-exit (boolean)
              if  true,  exit  when a command fails and the following command is unconditional (i.e.
              does not begin with || or &&). lftp exits after the unconditional  command  is  issued
              without executing it.

       cmd:interactive (tri-boolean)
              when  true,  lftp  acts interactively, handles terminal signals and outputs some extra
              messages. Default is auto and depends on stdin being a terminal.

       cmd:long-running (seconds)
              time of command execution, which is considered as `long' and a  beep  is  done  before
              next prompt. 0 means off.

       cmd:ls-default (string)
              default ls argument

       cmd:move-background (boolean)
              when false, lftp refuses to go to background when exiting. To force it, use `exit bg'.

       cmd:move-background-detach (boolean)
              when  true  (default),  lftp  detaches itself from the control terminal when moving to
              background, it is possible to attach back using `attach'  command;  when  false,  lftp
              tricks  the  shell to move lftp to background process group and continues to run, then
              fg shell command brings lftp back to foreground unless it has done all jobs and termi‐

       cmd:prompt (string)
              The  prompt.  lftp  recognizes the following backslash-escaped special characters that
              are decoded as follows:
              \@     insert @ if the current remote site user is not default
              \a     an ASCII bell character (07)
              \e     an ASCII escape character (033)
              \h     the remote hostname you are connected to
              \n     newline
              \s     the name of the client (lftp)
              \S     current slot name
              \u     the username of the remote site user you are logged in as
              \U     the URL of the remote site (e.g., ftp://g437.ub.gu.se/home/james/src/lftp)
              \v     the version of lftp (e.g., 2.0.3)
              \w     the current working directory at the remote site
              \W     the base name of the current working directory at the remote site
              \l     the current working directory at the local site
              \L     the base name of the current working directory at the local site
              \nnn   the character corresponding to the octal number nnn
              \\     a backslash
              \?     skips next character if previous substitution was empty.
              \[     begin a sequence of non-printing characters, which could be  used  to  embed  a
                     terminal control sequence into the prompt
              \]     end a sequence of non-printing characters

       cmd:parallel (number)
              Number  of jobs run in parallel in non-interactive mode. For example, this may be use‐
              ful for scripts with multiple `get' commands.  Note  that  setting  this  to  a  value
              greater  than  1 changes conditional execution behaviour, basically makes it inconsis‐

       cmd:queue-parallel (number)
              Number of jobs run in parallel in a queue.

       cmd:remote-completion (boolean)
              a boolean to control whether or not lftp uses remote completion. When  true,  Tab  key
              guesses if the word being completed should be a remote file name. Meta-Tab does remote
              completion always. So you can force remote completion with Meta-Tab  when  cmd:remote-
              completion is false or when the guess is wrong.

       cmd:save-cwd-history (boolean)
              when  true,  lftp  saves  last  CWD of each site to ~/.local/share/lftp/cwd_history or
              ~/.lftp/cwd_history, allowing to do ``cd -'' after lftp restart. Default is true.

       cmd:save-rl-history (boolean)
              when  true,  lftp  saves  readline  history   to   ~/.local/share/lftp/rl_history   or
              ~/.lftp/rl_history on exit.  Default is true.

       cmd:show-status (booleam)
              when false, lftp does not show status line on terminal. Default is true.

       cmd:set-term-status (boolean)
              when  true,  lftp  updates  terminal status if supported (e.g. xterm). The closure for
              this setting is the terminal type from TERM environment variable.

       cmd:status-interval (timeinterval)
              the time interval between status updates.

       cmd:stifle-rl-history (number)
              the number of lines to keep in readline history.

       cmd:term-status (string)
              the format string to use to display terminal status. The closure for this  setting  is
              the  terminal  type  from  TERM environment variable. Default uses ``tsl'' and ``fsl''
              termcap values.

              The following escapes are supported:

                   \a   bell
                   \e   escape
                   \n   new line
                   \s   "lftp"
                   \v   lftp version
                   \T   the status string

       cmd:time-style (string)
              This setting is the default value for cls --time-style option.

       cmd:trace (boolean)
              when true, lftp prints the commands it executes (like sh -x).

       cmd:verify-host (boolean)
              if true, lftp resolves host name immediately in `open' command.  It is  also  possible
              to  skip  the  check  for a single `open' command if `&' is given, or if ^Z is pressed
              during the check.

       cmd:verify-path (boolean)
              if true, lftp checks the path given in `cd' command.  It is also possible to skip  the
              check for a single `cd' command if `&' is given, or if ^Z is pressed during the check.
                   set cmd:verify-path/hftp://* false
                   cd directory &

       cmd:verify-path-cached (boolean)
              When false, `cd' to a directory known from cache as existent will succeed immediately.
              Otherwise the verification will depend on cmd:verify-path setting.

       color:use-color (tri-boolean)
              when  true,  cls  command  and  completion  output  colored file listings according to
              color:dir-colors setting.  When set to auto, colors are used when output is  a  termi‐

       color:dir-colors (string)
              file listing color description. By default the value of LS_COLORS environment variable
              is used. See dircolors(1).

       dns:SRV-query (boolean)
              query for SRV records and use them before gethostbyname. The SRV records are only used
              if port is not explicitly specified. See nlink(https://tools.ietf.org/html/rfc2052,RFC2052) for details.

       dns:cache-enable (boolean)
              enable DNS cache. If it is off, lftp resolves host name each time it reconnects.

       dns:cache-expire (time interval)
              time to live for DNS cache entries. It has format <number><unit>+, e.g.  1d12h30m5s or
              just 36h. To disable expiration, set it to `inf' or `never'.

       dns:cache-size (number)
              maximum number of DNS cache entries.

       dns:fatal-timeout (time interval)
              limit the time for DNS queries. If DNS server is unavailable too long, lftp will  fail
              to resolve a given host name. Set to `never' to disable.

       dns:order (list of protocol names)
              sets  the  order  of  DNS queries. Default is ``inet6 inet'' which means first look up
              address in inet6 family, then inet and use them  in  that  order.   To  disable  inet6
              (AAAA) lookup, set this variable to ``inet''.

       dns:use-fork (boolean)
              if true, lftp will fork before resolving host address. Default is true.

       dns:max-retries (number)
              If  zero, there is no limit on the number of times lftp will try to lookup an address.
              If > 0, lftp will try only this number of times to look up an address of each  address
              family in dns:order.

       file:charset (string)
              local character set. It is set from current locale initially.

       file:use-lock (boolean)
              when true, lftp uses advisory locking on local files when opening them.

       fish:auto-confirm (boolean)
              when  true,  lftp  answers ``yes'' to all ssh questions, in particular to the question
              about a new host key. Otherwise it answers ``no''.

       fish:charset (string)
              the character set used by fish server in requests, replies and file listings.  Default
              is empty which means the same as local.

       fish:connect-program (string)
              the  program to use for connecting to remote server. It should support `-l' option for
              user name, `-p' for port number. Default is `ssh -a -x'. You can set it to `rsh',  for

       fish:shell (string)
              use specified shell on server side. Default is /bin/sh. On some systems, /bin/sh exits
              when doing cd to a non-existent directory. lftp can handle that but it has  to  recon‐
              nect. Set it to /bin/bash for such systems if bash is installed.

       ftp:acct (string)
              Send  this string in ACCT command after login. The result is ignored.  The closure for
              this setting has format user@host.

       ftp:anon-pass (string)
              sets the password used for anonymous FTP access authentication.  Default is "lftp@".

       ftp:anon-user (string)
              sets the user name used for anonymous FTP access authentication.  Default  is  "anony‐

       ftp:auto-sync-mode (regex)
              if first server message matches this regex, turn on sync mode for that host.

       ftp:catch-size (boolean)
              when  there is no support for SIZE command, try to catch file size from the "150 Open‐
              ing data connection" reply.

       ftp:charset (string)
              the character set used by FTP server in requests, replies and file listings.   Default
              is empty which means the same as local. This setting is only used when the server does
              not support UTF8.

       ftp:client (string)
              the name of FTP client to send with CLNT command, if supported by server.   If  it  is
              empty, then no CLNT command will be sent.

       ftp:compressed-re (regex)
              files  with  matching name will be considered compressed and "MODE Z" will not be used
              for them.

       ftp:bind-data-socket (boolean)
              bind data socket to the interface of control connection (in passive mode).  Default is
              true, exception is the loopback interface.

       ftp:fix-pasv-address (boolean)
              if  true, lftp will try to correct address returned by server for PASV command in case
              when server address is in public network and PASV returns an address  from  a  private
              network. In this case lftp would substitute server address instead of the one returned
              by PASV command, port number would not be changed.  Default is true.

       ftp:fxp-passive-source (boolean)
              if true, lftp will try to set up source FTP server in passive  mode  first,  otherwise
              destination  one.  If first attempt fails, lftp tries to set them up the other way. If
              the other disposition fails too, lftp falls back to plain copy. See also ftp:use-fxp.

       ftp:home (string)
              Initial directory. Default is empty string which means auto. Set this to  `/'  if  you
              don't  like  the  look  of  %2F  in  FTP URLs. The closure for this setting has format

       ftp:ignore-pasv-address (boolean)
              If true, lftp uses control connection address instead of  the  one  returned  in  PASV
              reply for data connection. This can be useful for broken NATs.  Default is false.

       ftp:list-empty-ok (boolean)
              if  set  to  false,  empty  lists  from LIST command will be treated as incorrect, and
              another method (NLST) will be used.

       ftp:list-options (string)
              sets options which are always appended to LIST command. It can be useful to  set  this
              to `-a' if server does not show dot (hidden) files by default.  Default is empty.

       ftp:nop-interval (seconds)
              delay  between  NOOP  commands when downloading tail of a file. This is useful for FTP
              servers which send "Transfer complete" message before flushing data transfer. In  such
              cases NOOP commands can prevent connection timeout.

       ftp:passive-mode (boolean)
              sets  passive FTP mode. This can be useful if you are behind a firewall or a dumb mas‐
              querading router. In passive mode lftp uses PASV command, not the PORT  command  which
              is  used  in active mode. In passive mode lftp itself makes the data connection to the
              server; in active mode the server connects to lftp for data transfer. Passive mode  is
              the default.

       ftp:port-ipv4 (ipv4 address)
              specifies  an  IPv4 address to send with PORT command. Default is empty which means to
              send the address of local end of control connection.

       ftp:port-range (from-to)
              allowed port range for active mode.  Format is min-max, or `full' or `any' to indicate
              any port. Default is `full'.

       ftp:prefer-epsv (boolean)
              use EPSV as preferred passive mode. Default is `false'.

       ftp:proxy (URL)
              specifies  FTP  proxy to use.  To disable proxy set this to empty string. Note that it
              is a FTP proxy which uses FTP protocol, not FTP over HTTP. Default value is taken from
              environment  variable  ftp_proxy  if  it  starts  with  ``ftp://''.  If your FTP proxy
              requires authentication, specify user name and password  in  the  URL.   If  ftp:proxy
              starts  with  http://  then hftp protocol (FTP over HTTP proxy) is used instead of FTP

       ftp:proxy-auth-type (string)
              When set to ``joined'', lftp sends ``user@proxy_user@ftp.example.org'' as user name to
              proxy, and ``password@proxy_password'' as password.

              When  set  to  ``joined-acct'',  lftp  sends ``user@ftp.example.org proxy_user'' (with
              space) as user name to proxy. The site password is sent as usual and the  proxy  pass‐
              word is expected in the following ACCT command.

              When  set  to ``open'', lftp first sends proxy user and proxy password and then ``OPEN
              ftp.example.org'' followed by ``USER user''.  The site password is then sent as usual.

              When set to ``user'' (default), lftp first sends proxy user  and  proxy  password  and
              then ``user@ftp.example.org'' as user name.  The site password is then sent as usual.

              When set to ``proxy-user@host'', lftp first sends ``USER proxy_user@ftp.example.org'',
              then proxy password. The site user and password are then sent as usual.

       ftp:rest-list (boolean)
              allow usage of REST command before LIST command. This might be useful for large direc‐
              tories, but some FTP servers silently ignore REST before LIST.

       ftp:rest-stor (boolean)
              if false, lftp will not try to use REST before STOR. This can be useful for some buggy
              servers which corrupt (fill with zeros) the file if REST followed by STOR is used.

       ftp:retry-530 (regex)
              Retry on server reply 530 for PASS command if text matches  this  regular  expression.
              This setting should be useful to distinguish between overloaded server (temporary con‐
              dition) and incorrect password (permanent condition).

       ftp:retry-530-anonymous (regex)
              Additional regular expression for anonymous login, like ftp:retry-530.

       ftp:site-group (string)
              Send this string in SITE GROUP command after login. The result is ignored.   The  clo‐
              sure for this setting has format user@host.

       ftp:skey-allow (boolean)
              allow sending skey/opie reply if server appears to support it. On by default.

       ftp:skey-force (boolean)
              do  not send plain text password over the network, use skey/opie instead. If skey/opie
              is not available, assume failed login. Off by default.

       ftp:ssl-allow (boolean)
              if true, try to negotiate SSL connection with FTP  server  for  non-anonymous  access.
              Default  is  true. This and other SSL settings are only available if lftp was compiled
              with an ssl/tls library.

       ftp:ssl-auth (string)
              the argument for AUTH command, can be one of SSL, TLS, TLS-P, TLS-C.  See nlink(https://tools.ietf.org/html/rfc4217,RFC4217)  for
              explanations. By default TLS or SSL will be used, depending on FEAT reply.

       ftp:ssl-data-use-keys (boolean)
              if  true,  lftp  loads  ssl:key-file for protected data connection too. When false, it
              does not, and the server can  match  data  and  control  connections  by  session  ID.
              Default is true.

       ftp:ssl-force (boolean)
              if  true,  refuse to send password in clear when server does not support SSL.  Default
              is false.

       ftp:ssl-protect-data (boolean)
              if true, request SSL connection for data transfers. This is cpu-intensive but provides
              privacy. Default is false.

       ftp:ssl-protect-fxp (boolean)
              if true, request SSL connection for data transfer between two FTP servers in FXP mode.
              CPSV or SSCN command will be used in that case. If SSL connection fails for some  rea‐
              son,  lftp  would  try unprotected FXP transfer unless ftp:ssl-force is set for any of
              the two servers. Default is false.

       ftp:ssl-protect-list (boolean)
              if true, request SSL connection for file list transfers. Default is true.

       ftp:ssl-use-ccc (boolean)
              if true, lftp would issue CCC command after logon, thus disable ssl  protection  layer
              on control connection.

       ftp:stat-interval (time interval)
              interval between STAT commands. Default is 1 second.

       ftp:strict-multiline (boolean)
              when true, lftp strictly checks for multiline reply format (expects it to end with the
              same code as it started with). When false, this check is relaxed.

       ftp:sync-mode (boolean)
              if true, lftp will send one command at a time and wait for  response.  This  might  be
              useful  if  you  are  using a buggy FTP server or router. When it is off, lftp sends a
              pack of commands and waits for responses - it speeds up operation when round trip time
              is  significant.  Unfortunately it does not work with all FTP servers and some routers
              have troubles with it, so it is on by default.

       ftp:timezone (string)
              Assume this timezone for time in listings returned by LIST command.  This setting  can
              be  GMT  offset  [+|-]HH[:MM[:SS]]  or  any  valid  TZ  value  (e.g.  Europe/Moscow or
              MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT.  Set it to an empty  value  to  assume
              local timezone specified by environment variable TZ.

       ftp:trust-feat (string)
              When  true,  assume  that FEAT returned data are correct and don't use common protocol
              extensions like SIZE, MDTM, REST if they are not listed.  Default is false.

       ftp:use-abor (boolean)
              if false, lftp does not send ABOR command but closes data connection immediately.

       ftp:use-allo (boolean)
              when true (default), lftp sends ALLO command before uploading a file.

       ftp:use-feat (boolean)
              when true (default), lftp uses FEAT command to  determine  extended  features  of  ftp

       ftp:use-fxp (boolean)
              if true, lftp will try to set up direct connection between two ftp servers.

       ftp:use-hftp (boolean)
              when  ftp:proxy  points to an http proxy, this setting selects hftp method (GET, HEAD)
              when true, and CONNECT method when false. Default is true.

       ftp:use-ip-tos (boolean)
              when true, lftp uses IPTOS_LOWDELAY for control connection  and  IPTOS_THROUGHPUT  for
              data connections.

       ftp:lang (boolean)
              the  language  selected with LANG command, if supported as indicated by FEAT response.
              Default is empty which means server default.

       ftp:use-mdtm (boolean)
              when true (default), lftp uses MDTM command to determine file modification time.

       ftp:use-mdtm-overloaded (boolean)
              when true, lftp uses two argument MDTM  command  to  set  file  modification  time  on
              uploaded files. Default is false.

       ftp:use-mode-z (boolean)
              when  true,  lftp  will  use "MODE Z" if supported by the server to perform compressed

       ftp:use-site-idle (boolean)
              when true, lftp sends `SITE IDLE' command with net:idle argument. Default is false.

       ftp:use-site-utime (boolean)
              when true, lftp sends 5-argument `SITE UTIME' command to set file modification time on
              uploaded files. Default is true.

       ftp:use-site-utime2 (boolean)
              when true, lftp sends 2-argument `SITE UTIME' command to set file modification time on
              uploaded files. Default is true.  If 5-argument `SITE UTIME' is also enabled,  2-argu‐
              ment command is tried first.

       ftp:use-size (boolean)
              when true (default), lftp uses SIZE command to determine file size.

       ftp:use-stat (boolean)
              if  true,  lftp sends STAT command in FXP mode transfer to know how much data has been
              transferred. See also ftp:stat-interval. Default is true.

       ftp:use-stat-for-list (boolean)
              when true, lftp uses STAT instead of LIST command. By default  `.'  is  used  as  STAT
              argument. Using STAT, lftp avoids creating data connection for directory listing. Some
              servers require special options for STAT, use ftp:list-options to specify  them  (e.g.

       ftp:use-telnet-iac (boolean)
              when true (default), lftp uses TELNET IAC command and follows TELNET protocol as spec‐
              ified in nlink(https://tools.ietf.org/html/rfc959,RFC959). When false, it does not follow TELNET protocol and thus does not dou‐
              ble  255 (0xFF, 0377) character and does not prefix ABOR and STAT commands with TELNET
              IP+SYNCH signal.

       ftp:use-tvfs (tri-boolean)
              When set to auto, usage of TVFS feature depends on FEAT server reply.  Otherwise  this
              setting  tells whether use it or not. In short, if a server supports TVFS feature then
              it uses unix-like paths.

       ftp:use-utf8 (boolean)
              if true, lftp sends `OPTS UTF8 ON' to the server to activate UTF-8 encoding  (if  sup‐
              ported).  Disable  it if the file names have a different encoding and the server has a
              trouble with it.

       ftp:use-quit (boolean)
              if true, lftp sends QUIT before disconnecting from ftp server. Default is true.

       ftp:verify-address (boolean)
              verify that data connection comes from the network address of control connection peer.
              This  can possibly prevent data connection spoofing which can lead to data corruption.
              Unfortunately, this can fail for certain ftp servers with several network  interfaces,
              when they do not set outgoing address on data socket, so it is disabled by default.

       ftp:verify-port (boolean)
              verify that data connection has port 20 (ftp-data) on its remote end.  This can possi‐
              bly prevent data connection spoofing by users of remote host. Unfortunately, too  many
              windows  and  even unix ftp servers forget to set proper port on data connection, thus
              this check is off by default.

       ftp:web-mode (boolean)
              disconnect after closing data connection. This can be useful for  totally  broken  ftp
              servers. Default is false.

       hftp:proxy (URL)
              specifies  HTTP proxy for FTP-over-HTTP protocol (hftp). The protocol hftp cannot work
              without a HTTP proxy, obviously.  Default value is  taken  from  environment  variable
              ftp_proxy   if  it  starts  with  ``http://'',  otherwise  from  environment  variable
              http_proxy.  If your FTP proxy requires authentication, specify user name and password
              in the URL.

       hftp:use-allprop (boolean)
              if true, lftp will send `<allprop/>' request body in `PROPFIND' requests, otherwise it
              will send an empty request body.

       hftp:use-authorization (boolean)
              if set to off, lftp will send password as part of  URL  to  the  proxy.  This  may  be
              required for some proxies (e.g. M-soft). Default is on, and lftp will send password as
              part of Authorization header.

       hftp:use-head (boolean)
              if set to off, lftp will try to use `GET' instead of `HEAD' for hftp protocol.   While
              this  is slower, it may allow lftp to work with some proxies which don't understand or
              mishandle ``HEAD ftp://'' requests.

       hftp:use-mkcol (boolean)
              if set to off, lftp will try to use `PUT' instead of  `MKCOL'  to  create  directories
              with hftp protocol. Default is off.

       hftp:use-propfind (boolean)
              if set to off, lftp will not try to use `PROPFIND' to get directory contents with hftp
              protocol and use `GET' instead. Default is off.

       hftp:use-type (boolean)
              If set to off, lftp won't try to append `;type=' to URLs passed to proxy.  Some broken
              proxies don't handle it correctly. Default is on.

       http:accept, http:accept-charset, http:accept-encoding, http:accept-language (string)
              specify corresponding HTTP request headers.

       http:authorization (string)

              specifies  value  of  Content-Type  HTTP  request  header for POST method.  Default is

       http:proxy (URL)
              specifies HTTP proxy. It is used when lftp works over HTTP protocol.  Default value is
              taken  from  environment  variable http_proxy.  If your proxy requires authentication,
              specify user name and password in the URL.

       http:put-method (PUT or POST)
              specifies which HTTP method to use on put.

       http:put-content-type (string)
              specifies value of Content-Type HTTP request header for PUT method.

       http:referer (string)
              specifies value for Referer HTTP request header. Single dot  `.'  expands  to  current
              directory URL. Default is `.'. Set to empty string to disable Referer header.

       http:set-cookies (boolean)
              if true, lftp modifies http:cookie variables when Set-Cookie header is received.

       http:use-allprop (boolean)
              if true, lftp will send `<allprop/>' request body in `PROPFIND' requests, otherwise it
              will send an empty request body.

       http:use-mkcol (boolean)
              if set to off, lftp will try to use `PUT' instead of  `MKCOL'  to  create  directories
              with HTTP protocol. Default is on.

       http:use-propfind (boolean)
              if set to off, lftp will not try to use `PROPFIND' to get directory contents with HTTP
              protocol and use `GET' instead. Default is on.

              specifies default exclusion pattern. You can override it by --include option.

       mirror:include-regex (regex)
              specifies  default  inclusion  pattern.  It is used just after mirror:exclude-regex is
              applied. It is never used if mirror:exclude-regex is empty.

       mirror:no-empty-dirs (boolean)
              when true, mirror doesn't create empty directories (like --no-empty-dirs option).

       mirror:sort-by (string)
              specifies order of file transfers. Valid values are: name, name-desc, size, size-desc,
              date,  date-desc.  When the value is name or name-desc, then mirror:order setting also
              affects the order or transfers.

       mirror:order (list of patterns)
              specifies order of file transfers when sorting by name. E.g. setting  this  to  "*.sfv
              *.sum"  makes  mirror to transfer files matching *.sfv first, then ones matching *.sum
              and then all other files. To process directories after other files, add  "*/"  to  the
              end of pattern list.

       mirror:overwrite (boolean)
              when true, mirror will overwrite plain files instead of removing and re-creating them.

       mirror:parallel-directories (boolean)
              if true, mirror will start processing of several directories in parallel when it is in
              parallel mode. Otherwise, it will transfer files from a single directory before moving
              to other directories.

       mirror:parallel-transfer-count (number)
              specifies  number of parallel transfers mirror is allowed to start. Default is 1.  You
              can override it with --parallel option.

       mirror:require-source (boolean)
              When true, mirror requires a source directory to be specified explicitly, otherwise it
              is supposed to be the current directory.

       mirror:set-permissions (boolean)
              When  set  to  off,  mirror won't try to copy file and directory permissions.  You can
              override it by --perms option. Default is on.

       mirror:skip-noaccess (boolean)
              when true, mirror does not try to download files which are obviously  inaccessible  by
              the permission mask. Default is false.

              disconnect from server after this idle time. Default is 3 minutes.

       net:limit-rate (bytes per second)
              limit transfer rate on data connection. 0 means unlimited. You can specify two numbers
              separated  by  colon  to limit download and upload rate separately.  Suffixes are sup‐
              ported, e.g. 100K means 102400.

       net:limit-max (bytes)
              limit accumulating of unused limit-rate. 0 means twice of limit-rate.

       net:limit-total-rate (bytes per second)
              limit transfer rate of all connections in sum. 0 means unlimited. You can specify  two
              numbers  separated  by  colon to limit download and upload rate separately.  Note that
              sockets have receive buffers on them, this can lead to network link load  higher  than
              this rate limit just after transfer beginning. You can try to set net:socket-buffer to
              relatively small value to avoid this.

       net:limit-total-max (bytes)
              limit accumulating of unused limit-total-rate. 0 means twice of limit-total-rate.

       net:max-retries (number)

              5xx when there is too many users.

       net:reconnect-interval-base (seconds)
              sets  the  base minimal time between reconnects. Actual interval depends on net:recon‐
              nect-interval-multiplier and number of attempts to perform an operation.

       net:reconnect-interval-max (seconds)
              sets maximum  reconnect  interval.  When  current  interval  after  multiplication  by
              net:reconnect-interval-multiplier reaches this value (or exceeds it), it is reset back
              to net:reconnect-interval-base.

       net:reconnect-interval-multiplier (real number)
              sets multiplier by which base interval is multiplied each time new attempt to  perform
              an  operation fails. When the interval reaches maximum, it is reset to base value. See
              net:reconnect-interval-base and net:reconnect-interval-max.

       you can get a particular settings for particular state. The closure is to be specified  after
       variable name separated with slash `/'.

       The  closure  for `dns:', `net:', `ftp:', `http:', `hftp:' domain variables is currently just
       the host name as you specify it in the `open' command (with some exceptions where closure  is
       meaningless,  e.g.  dns:cache-size).  For some `cmd:' domain variables the closure is current
       URL without path.  For other variables it is not currently used. See examples in  the  sample

       Certain  commands  and  settings take a time interval parameter. It has the format Nx[Nx...],
       where N is time amount (floating point) and x is time unit: d - days, h - hours, m - minutes,
       s  -  seconds.  Default unit is second. E.g. 5h30m or 5.5h.  Also the interval can be `infin‐
       ity', `inf', `never', `forever' - it means infinite interval. E.g. `sleep  forever'  or  `set
       dns:cache-expire never'.

       Boolean  settings can be one of (true, on, yes, 1, +) for a True value or one of (false, off,
       no, 0, -) for a False value.

       Tri-boolean settings have either a boolean value or `auto'.

       Integer settings can have a suffix: k - kibi, m - mebi, g - gigi, etc.  They can also have  a
       prefix: 0 - octal, 0x - hexadecimal.

   FTP asynchronous mode (pipelining)
       Lftp  can  speed  up FTP operations by sending several commands at once and then checking all
       the responses. See ftp:sync-mode variable. Sometimes this does  not  work,  thus  synchronous
       mode is the default. You can try to turn synchronous mode off and see if it works for you. It
       is known that some network software dealing with address translation works incorrectly in the
       case of several FTP commands in one network packet.

       RFC959  says: ``The user-process sending another command before the completion reply would be
       in violation of protocol; but server-FTP processes should  queue  any  commands  that  arrive
       while  a  preceding  command  is  in  progress''. Also, RFC1123 says: ``Implementors MUST NOT
       assume any correspondence between READ boundaries on the control connection  and  the  Telnet
       EOL  sequences  (CR  LF).''  and ``a single READ from the control connection may include more
       than one FTP command''.

       So it must be safe to send several commands at once, which speeds  up  operation  a  lot  and
       seems  to  work with all Unix and VMS based ftp servers. Unfortunately, windows based servers
       often cannot handle several commands in one packet, and so cannot some broken routers.

       -d     Switch on debugging mode.

       -e commands
              Execute given commands and don't exit.

       -p port
              Use the given port to connect.

       -u user[,pass]
              Use the given username and password to connect. Remember to quote the  password  prop‐
              erly  in the shell. Also note that it is not secure to specify the password on command
              line,  use  ~/.netrc  file  or  LFTP_PASSWORD  environment  variable   together   with
              --env-password  option.  Alternatively you can use ssh-based protocols with authorized
              keys, so you don't have to enter a password.

       --norc Don't execute rc files from the home directory.

       -f script_file
              Execute commands in the file and exit.  This option must be used alone  without  other
              arguments (except --norc).

       -c commands
              Execute  the given commands and exit. Commands can be separated with a semicolon, `&&'
              or `||'. Remember to quote the commands argument properly in the shell.   This  option
              must be used alone without other arguments (except --norc).

       Other open options may also be given on the lftp command line.

       The following environment variables are processed by lftp:

       EDITOR Used as local editor for the edit command.

       HOME   Used for (local) tilde (`~') expansion.

       SHELL  Used by the ! command to determine the shell to run.

       PAGER  This  should  be  the  name of the pager to use.  It's used by the more and zmore com‐

       http_proxy, https_proxy
              Used to set initial http:proxy, hftp:proxy and https:proxy variables.

              Used to set initial ftp:proxy or hftp:proxy variables, depending on URL protocol  used
              in this environment variable.

              Used to set initial net:no-proxy variable.

              Used to set initial module:path variable.

              Used  to locate the directory that stores user-specific configuration files. If unset,
              ~/.lftp will be used. Please note that if this directory  does  not  exist,  then  XDG
              directories will be used.

              Used for --env-password open option.

              used to set initial color:dir-colors variable.

              Used  to  locate  the  directories for user-specific files when ~/.lftp (or $LFTP_HOME
              directory) does not exist. Defaults are ~/.config, ~/.local/share and ~/.cache respec‐
              tively. The suffix /lftp is appended to make the full path to the directories.

              system-wide startup file. Actual location depends on --sysconfdir configure option. It
              is /etc when prefix is /usr, /usr/local/etc by default.

       ~/.config/lftp/rc or ~/.lftp/rc, ~/.lftprc
              These files are executed on lftp startup after /etc/lftp.conf.

       ~/.local/share/lftp/log or ~/.lftp/log
              The file things are logged to when lftp moves into the background in nohup mode.

       ~/.local/share/lftp/transfer_log or ~/.lftp/transfer_log
              The file transfers are logged to when xfer:log setting is set to `yes'.  The  location
              can be changed by xfer:log-file setting.

       ~/.local/share/lftp/bookmarks or ~/.lftp/bookmarks
              The file is used to store lftp's bookmarks.  See the bookmark command.

       ~/.local/share/lftp/cwd_history or ~/.lftp/cwd_history
              The file is used to store last working directories for each site visited.

       ~/.local/share/lftp/bg/ or ~/.lftp/bg/
              The directory is used to store named sockets for backgrounded lftp processes.

       ~/.cache/lftp/DHT/ or ~/.lftp/DHT/"
              The  directory  is  used to store DHT id and nodes cache for IPv4 and IPv6.  File name
              suffix is the host name.

       ~/.cache/lftp/edit/ or ~/.lftp/edit/"
              The directory is used to store temporary files for edit command.

       ~/.local/share/lftp/torrent/md/ or ~/.lftp/torrent/md/"
              The directory is used to store torrent metadata. It is especially  useful  for  magnet
              links, cached metadata can be loaded from the directory.  It can also serve as torrent
              history, file names are the info_hash of torrents.

              The file is consulted to get default login and password to FTP server.  Passwords  are
              also searched here if an URL with user name but with no password is used.
