# Commands
This section shows information about builtin 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 effected 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 '-'.
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 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 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 given arguments to the message line at the bottom.
echomsg
Print 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 builtin 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 ':')

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', in order to use that 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.
# 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.

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 assigned 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>')

# 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, find command starts matching patterns from the beginning of file names, otherwise, it can match at an arbitrary position.
autoquit bool (default false)
Automatically quit server when there are no clients left connected.
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 had its preview cache disabled.
Five 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.
Preview clearing is disabled when the value of this option is left empty.
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".
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.
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.
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, only files with hidden attributes are considered hidden files.
hiddenfiles []string (default '.*')
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 and 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 '')
List of information shown for directory items at the right side of pane.
Currently supported information types are 'size', 'time', 'atime', and 'ctime'.
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.
mouse bool (default false)
Send mouse events as input.
number bool (default false)
Show the position number for directory items at the left side of pane.
When '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.
preview bool (default true)
Show previews of files and directories at the right most pane.
If the file has more lines than the preview pane, 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.
Five 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 host name, '%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.
Home folder is shown as '~' in the working directory expansion.
Directory names are automatically shortened to a single character starting from the left most parent when the prompt does not fit to 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 'preview' option is enabled, the right most number is used for the width of preview pane.
relativenumber bool (default false)
Show the position number relative to the current line.
When 'number' is enabled, current line shows the absolute position, otherwise nothing is shown.
reverse bool (default false)
Reverse the direction of sort.
ruler []string (default 'acc:progress:selection:ind')
List of information shown in status line ruler.
Currently supported information types are 'acc', 'progress', 'selection', 'ind' and 'df'.
selmode string (default 'all')
Selection mode for commands.
When set to 'all' it will use the selected files from all directories.
When set to 'dir' it will only use the selected files in the current directory.
scrolloff int (default 0)
Minimum number of offset lines shown at all times in the top and the bottom of the screen when scrolling.
The current line is kept in the middle when this option is set to a large value that is bigger than the half of number of lines.
A smaller offset can be used when the current file is close to the beginning or end of the list to show the maximum number of items.
shell string (default 'sh' for Unix and 'cmd' for Windows)
Shell executable to use for shell commands.
Shell commands are executed as 'shell shellopts shellflag command -- arguments'.
shellflag string (default '-c' for Unix and '/c' for Windows)
Command line flag used to pass shell commands.
shellopts []string (default '')
List of shell options to pass to the shell executable.
smartcase bool (default true)
Override 'ignorecase' option when the pattern contains an uppercase character.
This option has no effect when 'ignorecase' is disabled.
smartdia bool (default false)
Override 'ignoredia' option when the pattern contains a character with diacritic.
This option has no effect when 'ignoredia' is disabled.
sortby string (default 'natural')
Sort type for directories.
Currently supported sort types are 'natural', 'name', 'size', 'time', 'ctime', 'atime', and 'ext'.
tabstop int (default 8)
Number of space characters to show for horizontal tabulation (U+0009) character.
tagfmt string (default "\033[31m")
Format string of the tags.
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".
tempmarks string (default '')
Marks to be considered temporary (e.g. 'abc' refers to marks 'a', 'b', and 'c').
These marks are not synced to other clients and they are not saved in the bookmarks file.
Note that the special bookmark "'" is always treated as temporary and it does not need to be specified.
timefmt string (default 'Mon Jan _2 15:04:05 2006')
Format string of the file modification time shown in the bottom line.
truncatechar string (default '~')
Truncate character shown at the end when the file name does not fit to the pane.
waitmsg string (default 'Press any key to continue')
String shown after commands of shell-wait type.
wrapscan bool (default true)
Searching can wrap around the file list.
wrapscroll bool (default false)
Scrolling can wrap around the file list.
user_{option} string (default none)
Any option that is prefixed with 'user_' is a user defined option and can be set to any string.
Inside a user defined command the value will be provided in the `lf_user_{option}` environment variable.
These options are not used by lf and are not persisted.
# Environment Variables
The following variables are exported for shell commands:
These are referred with a '$' prefix on POSIX shells (e.g. '$f'), between '%' characters on Windows cmd (e.g. '%f%'), and with a '$env:' prefix on Windows powershell (e.g. '$env:f').
f
Current file selection as a full path.
fs
Selected file(s) separated with the value of 'filesep' option as full path(s).
fx
Selected file(s) (i.e. 'fs') if there are any selected files, otherwise current file selection (i.e. 'f').
id

PWD
Present working directory.
OLDPWD
Initial working directory.
LF_LEVEL
The value of this variable is set to the current nesting level when you run lf from a shell spawned inside lf.
You can add the value of this variable to your shell prompt to make it clear that your shell runs inside lf.
For example, with POSIX shells, you can use '[ -n "$LF_LEVEL" ] && PS1="$PS1""(lf level: $LF_LEVEL) "' in your shell configuration file (e.g. '~/.bashrc').
OPENER
If this variable is set in the environment, use the same value. Otherwise, this is set to 'start' in Windows, 'open' in MacOS, 'xdg-open' in others.
EDITOR
If VISUAL is set in the environment, use its value. Otherwise, use the value of the environment variable EDITOR. If neither variable is set, this is set to 'vi' on Unix, 'notepad' in Windows.
PAGER
If this variable is set in the environment, use the same value. Otherwise, this is set to 'less' on Unix, 'more' in Windows.
SHELL
If this variable is set in the environment, use the same value. Otherwise, this is set to 'sh' on Unix, 'cmd' in Windows.
lf
Absolute path to the currently running lf binary, if it can be found. Otherwise, this is set to the string 'lf'.
lf_{option}
Value of the {option}.
lf_user_{option}
Value of the user_{option}.
lf_width
lf_height
Width/Height of the terminal.
lf_count
Value of the count associated with the current command.
