VERSION¶
This man page documents lftp version 4.6.0.
DESCRIPTION¶
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 automatically. 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 background. All background jobs are
executed in the same single process. You can bring a foreground 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 conditionally 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
~/.config/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.

Commands¶
! shell command
Launch shell or shell command.
!ls
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
name |
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 connections.
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 |
-B, |

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 $@, corresponding 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 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 [
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 |
ftpcopy

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 false.
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 specifying multiple
instances of
rfile (and -o
lfile). Does not expand wildcards,
use
mget for that.

delete source files after successful transfer |
-e |
delete target file before the transfer |
-a |
use ascii mode (binary is the default) |

|
same as --allow-chown --allow-suid --no-umask |
When using -R, the source directory is local and the target is remote. If the
target directory 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 directory 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 protocol cannot do it. To upload files the links refer to, use
`mirror -RL' command (treat symbolic 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.
You can mirror between two servers if you specify URLs instead of directories.
FXP is automatically 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 module_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
zmore)
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 [
-e cmd]
[-u
user[,
pass]] [-p
port]
host|url
Select a 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' commands, it may confuse lftp. Instead do the cd/lcd
before `queue' command, and it will remember the place in which the command is
to be done. It is possible to queue up an already running 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 automatically.
`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. |
Examples:
> 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. |
Examples:
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 messages.
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, somewhat 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 location.
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
suspend
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 downloaded.
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.
Options:
-O <directory> |
specifies base directory where files should be placed |
--force-valid |
skip file validation (if you are sure they are ok). |
--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 password will be cached so that future URL references can use it.
version
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)
Settings¶
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 protocol
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 directory, 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

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

- 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 terminated.

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

- the time interval between status updates.
- cmd:stifle-rl-history (number)
- the number of lines to keep in readline history.
- cmd:term-status (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).

- 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.
- 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 terminal.
- 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 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: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 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
"lftp@".
- ftp:anon-user (string)
- sets the user name used for anonymous FTP access authentication. Default
is "anonymous".
- 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 Opening 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: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 masquerading 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
automatically.
- 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 password 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 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 closure 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
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 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: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 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: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-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-argument 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. -la).
- 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-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 supported). 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 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.

- 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.

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

- 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.
- http:user-agent (string)

- 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. You can
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: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: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.

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)

- 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.

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.
- 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

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, you should 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)

validate file integrity. Zero exit code of that command should indicate
correctness of the file.
- xfer:verify-command (string)
- the command to validate file integrity. The only argument is the path to
the file.
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
lftp.conf.
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 `infinity', `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.
OPTIONS¶
- -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 properly in the shell. Also note that it is not secure to specify
the password on command line, use ~/.netrc file. 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).
ENVIRONMENT VARIABLES¶
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 commands.
- http_proxy, https_proxy
- Used to set initial http:proxy, hftp:proxy and https:proxy variables.
- ftp_proxy
- Used to set initial ftp:proxy or hftp:proxy variables, depending on URL
protocol used in this environment variable.
- no_proxy
- Used to set initial net:no-proxy variable.
- LFTP_MODULE_PATH
- Used to set initial module:path variable.
- LFTP_HOME
- 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.
- LS_COLORS
- used to set initial color:dir-colors variable.
- XDG_CONFIG_DIR, XDG_DATA_DIR, XDG_CACHE_DIR
- 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 respectively.
The suffix /lftp is appended to make the full path to the
directories.
FILES¶
- /etc/lftp.conf
- 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.
- ~/.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.
- ~/.netrc
- 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.
