COMMANDS
This section shows information about built-in commands. Modal commands
do not take any arguments, but instead change the operation mode to read
their input conveniently, and so they are meant to be assigned to
keybindings.
quit (default q)
Quit lf and return to the shell.
up (default k and <up>), half-up (default <c-u>), page-up (default <c-b> and <pgup>), scroll-up (default <c-y>), down (default j and <down>), half-down (default <c-d>), page-down (default <c-f> and <pgdn>), scroll-down (default <c-e>)
Move/scroll the current file selection upwards/downwards by one/half a
page/full page.
updir (default h and <left>)
Change the current working directory to the parent directory.
open (default l and <right>)
If the current file is a directory, then change the current directory to
it, otherwise, execute the open command. A default open command is
provided to call the default system opener asynchronously with the
current file as the argument. A custom open command can be defined to
override this default.
jump-next (default ]), jump-prev (default [)
Change the current working directory to the next/previous jumplist item.
top (default gg and <home>), bottom (default G and <end>)
Move the current file selection to the top/bottom of the directory. A
count can be specified to move to a specific line, for example, use 3G
to move to the third line.
high (default H), middle (default M), low (default L)
Move the current file selection to the high/middle/low of the screen.
toggle
Toggle the selection of the current file or files given as arguments.
invert (default v)
Reverse the selection of all files in the current directory (i.e. toggle
all files). Selections in other directories are not affected by this
command. You can define a new command to select all files in the
directory by combining invert with unselect (i.e.
cmd select-all :unselect; invert), though this will also remove
selections in other directories.
invert-below
Reverse the selection (i.e. toggle) of all files at or after the current
file in the current directory.
To select a contiguous block of files, use this command on the first
file you want to select. Then, move down to the first file you do not
want to select (the one after the end of the desired selection) and use
this command again. This achieves an effect similar to the visual mode
in Vim.
This command is experimental and may be removed once a better
replacement for the visual mode is implemented in lf. If you'd like to
experiment with using this command, you should bind it to a key (e.g. V)
for a better experience.
unselect (default u)
Remove the selection of all files in all directories.
glob-select, glob-unselect
Select/unselect files that match the given glob.
calcdirsize
Calculate the total size for each of the selected directories. Option
info should include size and option dircounts should be disabled to show
this size. If the total size of a directory is not calculated, it will
be shown as -.
clearmaps
Remove all keybindings associated with the map command. This command can
be used in the config file to remove the default keybindings. For safety
purposes, : is left mapped to the read command, and cmap keybindings are
retained so that it is still possible to exit lf using :quit.
copy (default y)
If there are no selections, save the path of the current file to the
copy buffer, otherwise, copy the paths of selected files.
cut (default d)
If there are no selections, save the path of the current file to the cut
buffer, otherwise, copy the paths of selected files.
paste (default p)
Copy/Move files in the copy/cut buffer to the current working directory.
A custom paste command can be defined to override this default.
clear (default c)
Clear file paths in copy/cut buffer.
sync
Synchronize copied/cut files with the server. This command is
automatically called when required.
draw
Draw the screen. This command is automatically called when required.
redraw (default <c-l>)
Synchronize the terminal and redraw the screen.
load
Load modified files and directories. This command is automatically
called when required.
reload (default <c-r>)
Flush the cache and reload all files and directories.
echo
Print the given arguments to the message line at the bottom.
echomsg
Print the given arguments to the message line at the bottom and also to
the log file.
echoerr
Print given arguments to the message line at the bottom as errorfmt and
also to the log file.
cd
Change the working directory to the given argument.
select
Change the current file selection to the given argument.
delete (modal)
Remove the current file or selected file(s). A custom delete command can
be defined to override this default.
rename (modal) (default r)
Rename the current file using the built-in method. A custom rename
command can be defined to override this default.
source
Read the configuration file given in the argument.
push
Simulate key pushes given in the argument.
read (modal) (default :)
Read a command to evaluate.
shell (modal) (default $)
Read a shell command to execute.
shell-pipe (modal) (default %)
Read a shell command to execute piping its standard I/O to the bottom
statline.
shell-wait (modal) (default !)
Read a shell command to execute and wait for a key press in the end.
shell-async (modal) (default &)
Read a shell command to execute asynchronously without standard I/O.
find (modal) (default f), find-back (modal) (default F), find-next (default ;), find-prev (default ,)
Read key(s) to find the appropriate file name match in the
forward/backward direction and jump to the next/previous match.
search (default /), search-back (default ?), search-next (default n), search-prev (default N)
Read a pattern to search for a file name match in the forward/backward
direction and jump to the next/previous match.
filter (modal), setfilter
Command filter reads a pattern to filter out and only view files
matching the pattern. Command setfilter does the same but uses an
argument to set the filter immediately. You can supply an argument to
filter to use as the starting prompt.
mark-save (modal) (default m)
Save the current directory as a bookmark assigned to the given key.
mark-load (modal) (default ')
Change the current directory to the bookmark assigned to the given key.
A special bookmark ' holds the previous directory after a mark-load, cd,
or select command.
mark-remove (modal) (default ")
Remove a bookmark assigned to the given key.
tag
Tag a file with * or a single-width character given in the argument. You
can define a new tag-clearing command by combining tag with tag-toggle
(i.e. cmd tag-clear :tag; tag-toggle).
tag-toggle (default t)
Tag a file with * or a single width character given in the argument if
the file is untagged, otherwise remove the tag.
tty-write
Write the given string to the tty. This is useful for sending escape
sequences to the terminal to control its behavior (e.g. OSC 0 to set the
window title). Using tty-write is preferred over directly writing to
/dev/tty because the latter is not synchronized and can interfere with
drawing the UI.
COMMAND LINE COMMANDS
The prompt character specifies which of the several command-line modes
you are in. For example, the read command takes you to the : mode.
When the cursor is at the first character in : mode, pressing one of the
keys !, $, %, or & takes you to the corresponding mode. You can go back
with cmd-delete-back (<backspace> by default).
The command line commands should be mostly compatible with readline
keybindings. A character refers to a Unicode code point, a word consists
of letters and digits, and a unix word consists of any non-blank
characters.
cmd-escape (default <esc>)
Quit command line mode and return to normal mode.
cmd-complete (default <tab>)
Autocomplete the current word.
cmd-menu-complete, cmd-menu-complete-back
Autocomplete the current word with the menu selection. You need to
assign keys to these commands (e.g.
cmap <tab> cmd-menu-complete; cmap <backtab> cmd-menu-complete-back).
You can use the assigned keys to display the menu and then cycle through
completion options.
cmd-menu-accept
Accept the currently selected match in menu completion and close the
menu.
cmd-enter (default <c-j> and <enter>)
Execute the current line.
cmd-interrupt (default <c-c>)
Interrupt the current shell-pipe command and return to the normal mode.
cmd-history-next (default <c-n> and <down>), cmd-history-prev (default <c-p> and <up>)
Go to the next/previous item in the history.
cmd-left (default <c-b> and <left>), cmd-right (default <c-f> and <right>)
Move the cursor to the left/right.
cmd-home (default <c-a> and <home>), cmd-end (default <c-e> and <end>)
Move the cursor to the beginning/end of the line.
cmd-delete (default <c-d> and <delete>)
Delete the next character.
cmd-delete-back (default <backspace> and <backspace2>)
Delete the previous character. When at the beginning of a prompt,
returns either to normal mode or to : mode.
cmd-delete-home (default <c-u>), cmd-delete-end (default <c-k>)
Delete everything up to the beginning/end of the line.
cmd-delete-unix-word (default <c-w>)
Delete the previous unix word.
cmd-yank (default <c-y>)
Paste the buffer content containing the last deleted item.
cmd-transpose (default <c-t>), cmd-transpose-word (default <a-t>)
Transpose the positions of the last two characters/words.
cmd-word (default <a-f>), cmd-word-back (default <a-b>)
Move the cursor by one word in the forward/backward direction.
cmd-delete-word (default <a-d>)
Delete the next word in the forward direction.
cmd-delete-word-back (default <a-backspace> and <a-backspace2>)
Delete the previous word in the backward direction.
cmd-capitalize-word (default <a-c>), cmd-uppercase-word (default <a-u>), cmd-lowercase-word (default <a-l>)
Capitalize/uppercase/lowercase the current word and jump to the next
word.
OPTIONS
This section shows information about options to customize the behavior.
Character : is used as the separator for list options []int and
[]string.
anchorfind (bool) (default true)
When this option is enabled, the find command starts matching patterns
from the beginning of file names, otherwise, it can match at an
arbitrary position.
autoquit (bool) (default true)
Automatically quit the server when there are no clients left connected.
borderfmt (string) (default \033[0m)
Format string of the box drawing characters enabled by the drawbox
option.
cleaner (string) (default ``) (not called if empty)
Set the path of a cleaner file. The file should be executable. This file
is called if previewing is enabled, the previewer is set, and the
previously selected file has its preview cache disabled. The following
arguments are passed to the file, (1) current file name, (2) width, (3)
height, (4) horizontal position, (5) vertical position of preview pane
and (6) next file name to be previewed respectively. Preview cleaning is
disabled when the value of this option is left empty.
copyfmt (string) (default \033[7;33m)
Format string of the indicator for files to be copied.
cursoractivefmt (string) (default \033[7m), cursorparentfmt string (default \033[7m), cursorpreviewfmt string (default \033[4m)
Format strings for highlighting the cursor. cursoractivefmt applies in
the current directory pane, cursorparentfmt applies in panes that show
parents of the current directory, and cursorpreviewfmt applies in panes
that preview directories.
The default is to make the active cursor and the parent directory cursor
inverted. The preview cursor is underlined.
Some other possibilities to consider for the preview or parent cursors:
an empty string for no cursor, \033[7;2m for dimmed inverted text
(visibility varies by terminal), \033[7;90m for inverted text with grey
(aka "brightblack") background.
If the format string contains the characters %s, it is interpreted as a
format string for fmt.Sprintf. Such a string should end with the
terminal reset sequence. For example, \033[4m%s\033[0m has the same
effect as \033[4m.
cutfmt (string) (default \033[7;31m)
Format string of the indicator for files to be cut.
dircache (bool) (default true)
Cache directory contents.
dircounts (bool) (default false)
When this option is enabled, directory sizes show the number of items
inside instead of the total size of the directory, which needs to be
calculated for each directory using calcdirsize. This information needs
to be calculated by reading the directory and counting the items inside.
Therefore, this option is disabled by default for performance reasons.
This option only has an effect when info has a size field and the pane
is wide enough to show the information. 999 items are counted per
directory at most, and bigger directories are shown as 999+.
dirfirst (bool) (default true)
Show directories first above regular files.
dironly (bool) (default false)
Show only directories.
dirpreviews (bool) (default false)
If enabled, directories will also be passed to the previewer script.
This allows custom previews for directories.
drawbox (bool) (default false)
Draw boxes around panes with box drawing characters.
dupfilefmt (string) (default %f.~%n~)
Format string of file name when creating duplicate files. With the
default format, copying a file abc.txt to the same directory will result
in a duplicate file called abc.txt.~1~. Special expansions are provided,
%f as the file name, %b for the basename (file name without extension),
%e as the extension (including the dot) and %n as the number of
duplicates.
errorfmt (string) (default \033[7;31;47m)
Format string of error messages shown in the bottom message line.
If the format string contains the characters %s, it is interpreted as a
format string for fmt.Sprintf. Such a string should end with the
terminal reset sequence. For example, \033[4m%s\033[0m has the same
effect as \033[4m.
filesep (string) (default \n)
File separator used in environment variables fs and fx.
findlen (int) (default 1)
Number of characters prompted for the find command. When this value is
set to 0, find command prompts until there is only a single match left.
globfilter (bool) (default false)
Patterns are treated as globs for the filter command, see globsearch for
more details.
globsearch (bool) (default false)
When this option is enabled, search command patterns are considered as
globs, otherwise, they are literals. With globbing, * matches any
sequence, ? matches any character, and [...] or [^...] matches character
sets or ranges. Otherwise, these characters are interpreted as they are.
hidden (bool) (default false)
Show hidden files. On Unix systems, hidden files are determined by the
value of hiddenfiles. On Windows, files with hidden attributes are also
considered hidden files.
hiddenfiles ([]string) (default .* for Unix and `` for Windows)
List of hidden file glob patterns. Patterns can be given as relative or
absolute paths. Globbing supports the usual special characters, * to
match any sequence, ? to match any character, and [...] or [^...] to
match character sets or ranges. In addition, if a pattern starts with !,
then its matches are excluded from hidden files. To add multiple
patterns, use : as a separator. Example: .*:lost+found:*.bak
history (bool) (default true)
Save command history.
icons (bool) (default false)
Show icons before each item in the list.
ifs (string) (default ``)
Sets IFS variable in shell commands. It works by adding the assignment
to the beginning of the command string as IFS=...; .... The reason is
that IFS variable is not inherited by the shell for security reasons.
This method assumes a POSIX shell syntax so it can fail for non-POSIX
shells. This option has no effect when the value is left empty. This
option does not have any effect on Windows.
ignorecase (bool) (default true)
Ignore case in sorting and search patterns.
ignoredia (bool) (default true)
Ignore diacritics in sorting and search patterns.
incsearch (bool) (default false)
Jump to the first match after each keystroke during searching.
incfilter (bool) (default false)
Apply filter pattern after each keystroke during filtering.
info ([]string) (default ``)
A list of information that is shown for directory items at the right
side of the pane. Currently supported information types are size, time,
atime, ctime, perm, user and group. Information is only shown when the
pane width is more than twice the width of information.
infotimefmtnew (string) (default Jan _2 15:04)
Format string of the file time shown in the info column when it matches
this year.
infotimefmtold (string) (default Jan _2 2006)
Format string of the file time shown in the info column when it doesn't
match this year.
locale (string) (default ``)
An IETF BCP 47 language tag (e.g. zh-CN) for specifying the locale used
when using sort type natural and name. An empty string means disable
locale ordering, and the special value * is used to indicate reading the
locale setting from the system environment. This feature is currently
experimental.
mouse (bool) (default false)
Send mouse events as input.
number (bool) (default false)
Show the position number for directory items on the left side of the
pane. When the relativenumber option is enabled, only the current line
shows the absolute position and relative positions are shown for the
rest.
numberfmt (string) (default \033[33m)
Format string of the position number for each line.
period (int) (default 0)
Set the interval in seconds for periodic checks of directory updates.
This works by periodically calling the load command. Note that
directories are already updated automatically in many cases. This option
can be useful when there is an external process changing the displayed
directory and you are not doing anything in lf. Periodic checks are
disabled when the value of this option is set to zero.
preserve ([]string) (default mode)
List of attributes that are preserved when copying files. Currently
supported attributes are mode (i.a. access mode) and timestamps (i.e.
modification time and access time). Note that preserving other
attributes like ownership of change/birth timestamp is desirable, but
not portably supported in Go.
preview (bool) (default true)
Show previews of files and directories at the rightmost pane. If the
file has more lines than the preview pane, the rest of the lines are not
read. Files containing the null character (U+0000) in the read portion
are considered binary files and displayed as binary.
previewer (string) (default ``) (not filtered if empty)
Set the path of a previewer file to filter the content of regular files
for previewing. The file should be executable. The following arguments
are passed to the file, (1) current file name, (2) width, (3) height,
(4) horizontal position, and (5) vertical position of preview pane
respectively. SIGPIPE signal is sent when enough lines are read. If the
previewer returns a non-zero exit code, then the preview cache for the
given file is disabled. This means that if the file is selected in the
future, the previewer is called once again. Preview filtering is
disabled and files are displayed as they are when the value of this
option is left empty.
promptfmt (string) (default \033[32;1m%u@%h\033[0m:\033[34;1m%d\033[0m\033[1m%f\033[0m)
Format string of the prompt shown in the top line. Special expansions
are provided, %u as the user name, %h as the hostname, %w as the working
directory, %d as the working directory with a trailing path separator,
%f as the file name, and %F as the current filter. %S may be used once
and will provide a spacer so that the following parts are right aligned
on the screen. The home folder is shown as ~ in the working directory
expansion. Directory names are automatically shortened to a single
character starting from the leftmost parent when the prompt does not fit
the screen.
ratios ([]int) (default 1:2:3)
List of ratios of pane widths. Number of items in the list determines
the number of panes in the UI. When the preview option is enabled, the
rightmost number is used for the width of the preview pane.
relativenumber (bool) (default false)
Show the position number relative to the current line. When number is
enabled, the current line shows the absolute position, otherwise nothing
is shown.
reverse (bool) (default false)
Reverse the direction of sort.
roundbox (bool) (default false)
Draw rounded outer corners when the drawbox option is enabled.
rulerfmt (string) (default %a| %p| \033[7;31m %m \033[0m| \033[7;33m %c \033[0m| \033[7;35m %s \033[0m| \033[7;34m %f \033[0m| %i/%t)
Format string of the ruler shown in the bottom right corner. Special
expansions are provided, %a as the pressed keys, %p as the progress of
file operations, %m as the number of files to be cut (moved), %c as the
number of files to be copied, %s as the number of selected files, %f as
the filter, %i as the position of the cursor, %t as the number of files
shown in the current directory, %h as the number of files hidden in the
current directory, and %d as the amount of free disk space remaining.
Additional expansions are provided for environment variables exported by
lf, in the form %{lf_<name>} (e.g. %{lf_selmode}). This is useful for
displaying the current settings. Expansions are also provided for
user-defined options, in the form %{lf_user_<name>} (e.g.
%{lf_user_foo}). The | character splits the format string into sections.
Any section containing a failed expansion (result is a blank string) is
discarded and not shown.
