.SH OPTIONS
This section shows information about options to customize the behavior. Character ':' is used as the separator for list options '[]int' and '[]string'.
.PP
.EX
anchorfind bool (default on)
.EE
.PP
When this option is enabled, find command starts matching patterns from the beginning of file names, otherwise, it can match at an arbitrary position.
.PP
.EX
autoquit bool (default off)
.EE
.PP
Automatically quit server when there are no clients left connected.
.PP
.EX
cleaner string (default '') (not called if empty)
.EE
.PP
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. One argument is passed to the file, path to the file whose preview should be cleaned. Preview clearing is disabled when the value of this option is left empty.
.PP
.EX
dircache bool (default on)
.EE
.PP
Cache directory contents.
.PP
.EX
dircounts bool (default off)
.EE
.PP
When this option is enabled, directory sizes show the number of items inside instead of the size of directory file. The former needs to be calculated by reading the directory and counting the items inside. The latter is directly provided by the operating system and it does not require any calculation, though it is non-intuitive and it can often be misleading. 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. A thousand items are counted per directory at most, and bigger directories are shown as '999+'.
.PP
.EX
dirfirst bool (default on)
.EE
.PP
Show directories first above regular files.
.PP
.EX
dironly bool (default off)
.EE
.PP
Show only directories.
.PP
.EX
drawbox bool (default off)
.EE
.PP
Draw boxes around panes with box drawing characters.
.PP
.EX
errorfmt string (default "\e033[7;31;47m%s\e033[0m")
.EE
.PP
Format string of error messages shown in the bottom message line.
.PP
.EX
filesep string (default "\en")
.EE
.PP
File separator used in environment variables 'fs' and 'fx'.
.PP
.EX
findlen int (default 1)
.EE
.PP
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.
.PP
.EX
globsearch bool (default off)
.EE
.PP
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.
.PP
.EX
hidden bool (default off)
.EE
.PP
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.
.PP
.EX
hiddenfiles []string (default '.*')
.EE
.PP
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.
.PP
.EX
icons bool (default off)
.EE
.PP
Show icons before each item in the list.
.PP
.EX
ifs string (default '')
.EE
.PP
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.
.PP
.EX
ignorecase bool (default on)
.EE
.PP
Ignore case in sorting and search patterns.
.PP
.EX
ignoredia bool (default on)
.EE

.EE
.PP
Apply filter pattern after each keystroke during filtering.
.PP
.EX
info []string (default '')
.EE
.PP
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.

.PP
.EX
period int (default 0)
.EE
.PP
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.
.PP
.EX
preview bool (default on)
.EE
.PP
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'.
.PP
.EX
previewer string (default '') (not filtered if empty)
.EE
.PP
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.
.PP
.EX
promptfmt string (default "\e033[32;1m%u@%h\e033[0m:\e033[34;1m%d\e033[0m\e033[1m%f\e033[0m")

Directory names are automatically shortened to a single character starting from the left most parent when the prompt does not fit to the screen.
.PP
.EX
ratios []int (default '1:2:3')

.PP
.EX
relativenumber bool (default off)
.EE
.PP
Show the position number relative to the current line. When 'number' is enabled, current line shows the absolute position, otherwise nothing is shown.
.PP
.EX

.EE
.PP
Reverse the direction of sort.
.PP
.EX
scrolloff int (default 0)
.EE
.PP
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.
.PP
.EX
shell string (default 'sh' for Unix and 'cmd' for Windows)
.EE
.PP
Shell executable to use for shell commands. Shell commands are executed as 'shell shellopts shellflag command -- arguments'.
.PP
.EX
