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.

--block-size=SIZE: with -l, scale sizes by SIZE when printing them; e.g., '--block-size=M'; 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 change 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]: color the output WHEN; more info below
-d, --directory: list directories themselves, not their contents
-D, --dired: generate output designed for Emacs' dired mode
-f: same as -a-U
-F, --classify[=WHEN]: append indicator (one of */=>@|) to entries WHEN

--full-time: like -l--time-style=full-iso
-g: like -l, but do not list owner
--group-directories-first: group directories before files
-G, --no-group: in a long listing, don't print group names
-h, --human-readable: with -l and -s, print sizes like 1K 234M 2G etc.

-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 (overrides QUOTING_STYLE environment variable)
-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: change default 'name' sort to WORD: none (-U), size (-S), time (-t), version (-v), extension (-X), name, width
--time=WORD: select which timestamp used to display or sort; access time (-u): atime, access, use; metadata change time (-c): ctime, status; modified time (default): mtime, modification; birth time: birth, creation;

: with -l, WORD determines which time to show; with --sort=time, sort by WORD (newest first)

--time-style=TIME_STYLE: time/date format with -l; see TIME_STYLE below
-t: sort by time, newest first; see --time
-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 directory entries
-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
--zero: end each output line with NUL, not newline
-1: list one file per line
--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,R,Q (powers of 1024) or KB,MB,... (powers of 1000). Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

The TIME_STYLE argument can be full-iso, long-iso, iso, locale, or +FORMAT. FORMAT is interpreted like in date(1). If FORMAT is FORMAT1<newline>FORMAT2, then FORMAT1 applies to non-recent files and FORMAT2 to recent files. TIME_STYLE prefixed with 'posix-' takes effect only outside the POSIX locale. Also the TIME_STYLE environment variable sets the default style to use.

The WHEN argument defaults to 'always' and can also be 'auto' or 'never'.

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(1) 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).
