SYNOPSIS
ls [,OPTION/]... [,FILE/]...DESCRIPTION
List information about the FILEs (the current directory by default). Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.
Mandatory arguments to long options are mandatory for short options too.
- -a, --all
- do not ignore entries starting with .
- -A, --almost-all
- do not list implied . and ..
- --author
- with -l, print the author of each file
- -b, --escape
- print C-style escapes for nongraphic characters
- --block-size=,SIZE/
- scale sizes by SIZE before printing them; e.g., '--block-size=M' prints sizes in units of 1,048,576 bytes; see SIZE format below
- -B, --ignore-backups
- do not list implied entries ending with ~
- -c
- with -lt: sort by, and show, ctime (time of last modification of file status information); with -l: show ctime and sort by name; otherwise: sort by ctime, newest first
- -C
- list entries by columns
- --color[=,WHEN/]
- colorize the output; WHEN can be 'always' (default if omitted), 'auto', or 'never'; more info below
- -d, --directory
- list directories themselves, not their contents
- -D, --dired
- generate output designed for Emacs' dired mode
- -f
- do not sort, enable -aU, disable -ls --color
- -F, --classify
- append indicator (one of */=>@|) to entries
- --file-type
- likewise, except do not append '*'
- --format=,WORD/
- across -x, commas -m, horizontal -x, long -l, single-column -1, verbose -l, vertical -C
- --full-time
- like -l --time-style=,full-iso/
- -g
- like -l, but do not list owner
- --group-directories-first
- group directories before files;
- can be augmented with a --sort option, but any use of --sort=,none/ (-U) disables grouping
- -G, --no-group
- in a long listing, don't print group names
- -h, --human-readable
- with -l and/or -s, print human readable sizes (e.g., 1K 234M 2G)
- --si
- likewise, but use powers of 1000 not 1024
- -H, --dereference-command-line
- follow symbolic links listed on the command line
- --dereference-command-line-symlink-to-dir
- follow each command line symbolic link
- that points to a directory
- --hide=,PATTERN/
- do not list implied entries matching shell PATTERN (overridden by -a or -A)
- --indicator-style=,WORD/
- append indicator with style WORD to entry names: none (default), slash (-p), file-type (--file-type), classify (-F)
- -i, --inode
- print the index number of each file
- -I, --ignore=,PATTERN/
- do not list implied entries matching shell PATTERN
- -k, --kibibytes
- default to 1024-byte blocks for disk usage
- -l
- use a long listing format
- -L, --dereference
- when showing file information for a symbolic link, show information for the file the link references rather than for the link itself
- -m
- fill width with a comma separated list of entries
- -n, --numeric-uid-gid
- like -l, but list numeric user and group IDs
- -N, --literal
- print raw entry names (don't treat e.g. control characters specially)
- -o
- like -l, but do not list group information
- -p, --indicator-style=,slash/
- append / indicator to directories
- -q, --hide-control-chars
- print ? instead of nongraphic characters
- --show-control-chars
- show nongraphic characters as-is (the default, unless program is 'ls' and output is a terminal)
- -Q, --quote-name
- enclose entry names in double quotes
- --quoting-style=,WORD/
- use quoting style WORD for entry names: literal, locale, shell, shell-always, shell-escape, shell-escape-always, c, escape
- -r, --reverse
- reverse order while sorting
- -R, --recursive
- list subdirectories recursively
- -s, --size
- print the allocated size of each file, in blocks
- -S
- sort by file size, largest first
- --sort=,WORD/
- sort by WORD instead of name: none (-U), size (-S), time (-t), version (-v), extension (-X)
- --time=,WORD/
- with -l, show time as WORD instead of default modification time: atime or access or use (-u); ctime or status (-c); also use specified time as sort key if --sort=,time/ (newest first)
- --time-style=,STYLE/
- with -l, show times using style STYLE: full-iso, long-iso, iso, locale, or +FORMAT; FORMAT is interpreted like in 'date'; if FORMAT is FORMAT1<newline>FORMAT2, then FORMAT1 applies to non-recent files and FORMAT2 to recent files; if STYLE is prefixed with 'posix-', STYLE takes effect only outside the POSIX locale
- -t
- sort by modification time, newest first
- -T, --tabsize=,COLS/
- assume tab stops at each COLS instead of 8
- -u
- with -lt: sort by, and show, access time; with -l: show access time and sort by name; otherwise: sort by access time, newest first
- -U
- do not sort; list entries in directory order
- -v
- natural sort of (version) numbers within text
- -w, --width=,COLS/
- set output width to COLS. 0 means no limit
- -x
- list entries by lines instead of by columns
- -X
- sort alphabetically by entry extension
- -Z, --context
- print any security context of each file
- -1
- list one file per line. Avoid '\n' with -q or -b
- --help
- display this help and exit
- --version
- output version information and exit
The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
Using color to distinguish file types is disabled both by default and with --color=,never/. With --color=,auto/, ls emits color codes only when standard output is connected to a terminal. The LS_COLORS environment variable can change the settings. Use the dircolors command to set it.
Exit status:
- 0
- if OK,
- 1
- if minor problems (e.g., cannot access subdirectory),
- 2
- if serious trouble (e.g., cannot access command-line argument).
