       This man page documents lftp version 3.5.0.

       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.

       handles  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).   Specify  the  method  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.

operations  are reliable, that is,  non fatal errors are ignored and the operation is repeated. If downloading is interrupted, it will be continued.  If ftp server does not support REST command, lftp will retrieve the file
       from the beginning until the file is transferred completely.

       A  shell-like command syntax allows the  launch multiple commands  in  parallel  in
       background  (&).  Commands are  groupd within  ( ) and executed in background. 
     Background jobs are executed in the same single process. 
    Use ^Z to push a job to background and 'wait' or 'fg' to pullm a job fom background.
    jobs lists running jobs. Some commands allow redirecting  
       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 background jobs are active when  lftp receives an exit lftp will move itself to nohup mode in
       background simiular to what hapens whend a modem hangup occurs  or when an xterm is closed.

      mirror downloads or updates a directory tree. 

       reverse mirror (mirror -R) uploads or updates a directory tree on server.  i
       Mirror  synchronizes directories between two remote servers, using FXP.

       at launch a job at specified time in current context, 
       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.  
       aliases and 'set' commands there. 
         To see full protocol  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. 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

       anon Sets the user to anonymous.  This is the default.

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

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

       cache  [subcommand] 
            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 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.  See 'help cls' for options.

       command cmd args...

       execute given command ignoring aliases.

       debug [-o file] level|off Switch debugging to level or turn it off.  Use -o to redirect the debug output to a file.

       echo [-n] string
       exit [bg] [top] [kill] [code] exit 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 kill' kills all num
       bered jobs before exiting. The options can be combined, e.g.  'at 08:00 -- exit top kill  &'
       kills all jobs and makes lftp exit at specified time.

       fg Alias for 'wait'.

       find  [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.

            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 isfalse.

       get [-E] [-a] [-c] [-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
       specifying multiple instances of rfile [and -o lfile]. Does not expand wildcards,  use  mget
       for that.
            -c        continue, reget
            -E        delete source files after successful 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)
                      transfer specified region of source file
                      position in target file to write data at

       glob [-d] [-a] [-f] command patterns 
       echo *''.
            -f   plain files (default)
            -d   directories
            -a   all types

       help [cmd]

       jobs [-v] List running jobs. -v means verbose, several -v can be specified.  
       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 '-'. 
       'lcd -' to change the directory back.

       lpwd 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 instead of current directory.
            -E        delete source files after successful transfer
            -a        use ascii mode (binary is the default)
            -O <base> specifies base directory or URL where files should be placed

       mirror [OPTS] [source [target]] Mirror specified source directory to local target directory.     
                        If target directory ends with a slash,  the  source base name 
                        is appended to target directory name. Source and/or target can be URLs pointing to directories.

            -c, --continue      continue a mirror job if possible
            -e, --delete        delete files not present at remote site
                --delete-first       delete old files before transferring new ones
            -s, --allow-suid         set suid/sgid bits according to remote site
                --allow-chown        try to set owner and group on files
                --ignore-time        ignore time when deciding whether to download
                --ignore-size        ignore size when deciding whether to download
                --only-missing       download only missing files
            -n, --only-newer         download only newer files (-c won't work)
            -r, --no-recursion       don't go to subdirectories
                --no-symlinks        don't create symbolic links
            -p, --no-perms      don't set file permissions
                --no-umask      don't apply umask to file modes
            -R, --reverse       reverse mirror (put files)
            -L, --dereference        download symbolic links as files
            -N, --newer-than=SPEC    download only files newer than specified time
                --older-than=SPEC    download only files older than specified time
                --size-range=RANGE   download only files with size in specified range
            -P, --parallel[=N]       download N files in parallel
                --use-pget[-n=N]     use pget to transfer every single file
                --loop               loop until no changes found
            -i RX, --include RX include matching files
            -x RX, --exclude RX exclude matching files
            -I GP, --include-glob GP include matching files
            -X GP, --exclude-glob GP exclude matching files
            -v, --verbose[=level]    verbose operation
                --log=FILE      write lftp commands being executed to FILE
                --script=FILE        write lftp commands to FILE, but don't execute them
                --just-print, --dry-run   same as --script=
                --use-cache          use cached directory listings
            --Remove-source-files    remove files after transfer (use with caution)
            -a             same as --allow-chown --allow-suid --no-umask

       When using -R, the first directory is local and the second is remote.  If the second  direcory  is
          omitted,  base  name of first directory is used.  If both directories are omitted,
       current local and remote directories are used.

       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  option  --newer-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.

       You  can mirror between two servers if you specify URLs instead of directories.  FXP is used
       automatically 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] dir(s) Make remote directories. If -p is used, make all components of paths.

       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) Removes specified file(s) with wildcard expansion.

       mv file1 file2 Rename file1 to file2.

       nlist [args] List remote file names

       open [-e cmd] [-u user[,pass]] [-p port] host|url Select an ftp server.

       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 setting)

       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 [ -c <count>] [[-d] delay] [command]

       Repeat  the  command. Between the commands a delay is inserted, by default 1 second.  Option
       '-c' limits number of repeations. Option '--while-ok' breaks loop when command returns  non
       zero exit code; '--until-ok' breaks on zero exit code.
            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
       directory remove. Be careful, if something goes wrong you can lose files. -f suppress  error

       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

       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.

       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 futute 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 termination.

       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.  You can place aliases and 'set' com
       mands there. Some people prefer to see full protocol debug, use 'debug' to  turn  the  debug

       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 ~/.lftp/bookmarks on 'bookmark add' command.  Off by

              the commands in string are executed before lftp exits.

       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 'ftp'.

       cmd:fail-exit (boolean)
              if true, exit when an unconditional (without || and && at begin) command fails.

       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

       cmd:prompt (string)
              The  prompt.  lftp recognizes the following backslash-escaped special characters that
              are decoded as follows:

              \@     insert @ if current user is not default
              \a     an ASCII bell character (07)
              \e     an ASCII escape character (033)
              \h     the hostname you are connected to
              \n     newline
              \s     the name of the client (lftp)
              \S     current slot name
              \u     the username of the 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
              \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:time-style (string)              default value for cls --time-style option.  
       cache:cache-empty-listings (boolean) When false, empty listings are not cached.  
       cache:enable (boolean)               When false, cache is disabled.  
       cache:expire (time interval)         Positive cache entries expire in this time interval.  
       cache:expire-negative (time interval) Negative cache entries expire in this time interval.  
       cache:size (number)                  Maximum cache size. When exceeded, oldest cache entries will be removed from cache.  
       cmd:remote-completion (boolean)      a boolean to control whether or not lftp uses remote completion.  
       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.  Examples:
                   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.

       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 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.  

       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 example.  
       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
              reconnect. 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 "-name@",
              where name is the username of the user running the program.  
       ftp:anon-user (string) sets the user name used for anonymous ftp access authentication.  Default is  "anony mous".  
       ftp:auto-sync-mode (regex) if first server message matches this regex, turn on sync mode for that host.  
       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: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 user@host.  
       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 indi
              cate any port. Default is 'full'.  
       ftp:proxy (URL) specifies ftp proxy to use.  To disable proxy set this to empty string. Note that  it
              is  an  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://, hftp (ftp over http proxy) is used instead of ftp automatically.  
       ftp:proxy-auth-joined (boolean) when true, lftp sends ''user@proxy_user@ftp.example.org'' as user name to proxy,  and
              ''password@proxy_password''  as  password.  When false, it first sends proxy user and
              proxy password and then ''user@ftp.example.org'' and password.

       ftp:rest-list (boolean) allow usage of REST command before LIST command.  This  might  be  useful  for  large
              directories, 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
              condition) 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 setting is only available if lftp was compiled with an  ssl/tls library.  
       ftp:ssl-force (boolean) if  trus, refuse to send password in clear when server does not support SSL.  Default
              is false. This setting is only  available  if  lftp  was  compiled  with  an  ssl/tls library.  
       ftp:ssl-protect-data (boolean) if  true,  request  ssl connection for data transfers. This is cpu-intensive but pro
              vides privacy. Default is false. This setting is only available if lftp was  compiled with an ssl/tls library.  
       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  reason, 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: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: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 server.  
       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: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-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 'SITE UTIME' command to set file modification time on  uploaded
              files. Default is true.  
       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-telnet-iac (boolean) when true (default), lftp uses TELNET IAC command  and  follows  TELNET  protocol  as
              specified in RFC959. When false, it does not follow TELNET protocol and thus does not
              double 255 (0xFF, 0377) character and does not prefix ABOR  and  STAT  commands  with TELNET IP+SYNCH signal.  
       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 possibly 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.

       ftps:initial-prot (string) specifies initial PROT setting for FTPS connections. Should be one of: C, S, E, P, or
              empty. Default is empty which means unknown, so  that  lftp  will  use  PROT  command
              unconditionally.  If  PROT command turns out to be unsupported, then Clear mode would be assumed.  

       hftp:cache (boolean) allow server/proxy side caching for ftp-over-http protocol.  
       hftp:cache-control (string) specify corresponding HTTP request header.  
       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 pass word in the URL.  
       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-language (string) specify corresponding HTTP request headers.  
       http:authorization (string) the  authorization  to  use  by  default,  when  no  user is specified. The format is
              ''user:password''. Default is empty which means no authorization.  
       http:cache (boolean) allow server/proxy side caching.  
       http:cache-control (string) specify corresponding HTTP request header.  
       http:cookie (string) send this cookie to server. A closure is useful here:
                   set cookie/www.somehost.com "param=value" 
       http:post-content-type (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  authentica
              tion, 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-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.  
       http:user-agent (string) the string lftp sends in User-Agent header of HTTP request.  
       https:proxy (string) specifies https proxy. Default value is taken from environment variable  https_proxy.  

       mirror:dereference (boolean) when true, mirror will dereference symbolic links by default.   
            override it by --no-dereference option. Default if false.  
       mirror:exclude-regex (regex) specifies default exclusion pattern. You can override it by --include option.  
       mirror:order (list of patterns) specifies order of file transfers. 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 end of pattern list.  
       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: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:use-pget-n (number) specifies -n option for pget command used to transfer every single file under mirror.
              Default is 1 which disables pget.  

       module:path (string) colon  separated list of directories to look for modules. 
                            Can be initialized by environment variable LFTP_MODULE_PATH. Default is 'PKGLIBDIR/VERSION:PKGLIBDIR'.  

       net:connection-limit (number) maximum number of concurrent connections to the same site. 0 means unlimited.  
       net:connection-takeover (boolean) if true, foreground connections have priority over background ones and can  interrupt
              background transfers to complete a foreground operation.  
       net:idle (time interval) 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. 
                                    Specify two numbers separated by colon to limit download and upload rate separately.  
       net:limit-max (bytes) limit accumulating of unused limit-rate. 0 means unlimited.  
       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 unlimited.  
       net:max-retries (number) the maximum number of sequential retries of an operation without  success.   0  means unlimited.  
       net:no-proxy (string) contains comma separated list of domains for which proxy should not be used.  Default
              is taken from environment variable no_proxy.  
       net:persist-retries (number) ignore this number of hard errors. Useful to login to buggy ftp servers  which  reply
              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 reachs 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 reachs maximum, it is reset to base value. See
              net:reconnect-interval-base and net:reconnect-interval-max.  
       net:socket-bind-ipv4 (ipv4 address) bind all IPv4 sockets to specified address. This can be useful to select  a  specific
              network  interface  to  use.  Default  is empty which means not to bind IPv4 sockets,
              operating system will choose an address automatically using routing table.  
       net:socket-bind-ipv6 (ipv6 address) the same for IPv6 sockets.  
       net:socket-buffer (bytes) use given size for SO_SNDBUF and SO_RCVBUF socket options. 0 means system default.  
       net:socket-maxseg (bytes) use given size for TCP_MAXSEG socket option. Not all operating systems  support  this option, but linux does.  
       net:timeout (time interval) sets the network protocol timeout.  

       pget:default-n (number) default number of chunks to split the file to in pget.  
       pget:save-status (time interval) save  pget transfer status this often. Set to 'never' to disable saving of the status
              file.  The status is saved to a file with suffix .lftp-pget-status.

       sftp:charset (string) the character set used by sftp server in file names and file  listings.   Default  is
              empty which means the same as local. This setting is only used for sftp protocol ver
              sion prior to 4. Version 4 and later always use UTF-8.  
       sftp: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 example.  
       sftp:max-packets-in-flight (number) The maximum number of unreplied packets in flight. If round trip time is significant,
              increase this and size-read/size-write. Default is 16.  
       sftp:protocol-version (number) The  protocol  number  to  negotiate.  Default is 4. The actual protocol version used depends on server.  
       sftp:server-program (string) The server program implementing SFTP protocol. If it does not contain a slash '/', it
              is  considered  a ssh2 subsystem and -s option is used when starting connect-program.
              Default is 'sftp'. You can use rsh as transport level protocol like this:
                   set sftp:connect-program rsh
                   set sftp:server-program /usr/libexec/openssh/sftp-server
              Similarly you can run sftp over ssh1.  
       sftp:size-read (number) Block size for reading. Default is 0x8000.  
       sftp:size-write (number) Block size for writing. Default is 0x8000.  
       ssl:ca-file (path to file) use specified file as Certificate Authority certificate.  
       ssl:ca-path (path to directory) use specified directory as Certificate Authority certificate repository.  
       ssl:crl-file (path to file) use specified file as Certificate Revocation List certificate.  
       ssl:crl-path (path to directory) use specified directory as Certificate Revocation List certificate repository.  
       ssl:key-file (path to file) use specified file as your private key.  
       ssl:cert-file (path to file) use specified file as your certificate.  
       ssl:verify-certificate (boolean) if set to yes, then verify server's certificate to be signed by a  known  Certificate
              Authority and not be on Certificate Revocation List.  
       xfer:clobber (boolean) if  this  setting is off, get commands will not overwrite existing files and generate
              an error instead. Default is on.  
       xfer:destination-directory (path or URL to directory)
              This setting is used as default -O option for get  and  mget  commands.   Default  is
              empty, which means current directory (no -O option).  
       xfer:eta-period (seconds) the period over which weighted average rate is calculated to produce ETA.  
       xfer:eta-terse (boolean) show terse ETA (only high order parts). Default is true.  
       xfer:max-redirections (number) maximum  number  of  redirections.  This  can  be  useful  for downloading over HTTP.
              Default is 0, which prohibits redirections.  
       xfer:rate-period (seconds) the period over which weighted average rate is calculated to be shown.  

       The name of a variable can be abbreviated unless it becomes ambiguous. The prefix before ':'
       can  be omitted too. You can set one variable several times for different closures, and thus
       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  -  min
       utes,  s  -  seconds.  Default unit is second. E.g. 5h30m or 5.5h.  Also the interval can be
       'infinity', 'inf', 'never', 'forever' - it means infinite interval. E.g. 'sleep forever'  or
       'set dns:cache-expire never'.

   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

       -f script_file Execute commands in the file and exit

       -c commands Execute the given commands and exit

       The following environment variables are processed by lftp:

       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.

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

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

              The file things are logged to when lftp moves into the background in nohup mode.

              The file is used to store lftp's bookmarks.  See the bookmark command.

              The file is used to store last working directories for each site visited.

              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.
