NAME

ls – list directory contents

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/: 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 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 -s, print sizes like 1K 234M 2G etc.
–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)
–hyperlink[=,WHEN/]: hyperlink file names; WHEN can be ‘always’ (default if omitted), ‘auto’, or ‘never’
–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; used only with -s and per directory totals
-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 entry names without quoting
-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/: sort by WORD instead of name: none (-U), size (-S), time (-t), version (-v), extension (-X)
–time=,WORD/: change the default of using modification times; access time (-u): atime, access, use; change time (-c): ctime, status; 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; 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 ‘
’ 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). 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.

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).
