LS(1)

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
    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 defaults to 'always' or can be 'never' or 'auto'. More info below

-d, --directory
    list directory entries instead of contents, and do not dereference symbolic links

-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.

    augment 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, print sizes in human readable format (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
    use 1024-byte blocks

-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 non graphic characters

--show-control-chars
    show non graphic characters as-is (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, 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

--sort=WORD
    sort by WORD instead of name: none -U, extension -X, size -S, time -t, version -v

--time=WORD
    with -l, show time as WORD instead of modification time: atime -u, access -u, use -u, ctime -c, or status -c; use specified time as sort key if --sort=time

--time-style=STYLE
    with -l, show times using style STYLE: full-iso, long-iso, iso, locale, +FORMAT. FORMAT is interpreted like 'date'; if FORMAT is FORMAT1<newline>FORMAT2, 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

-U  do not sort; list entries in directory order

-v  natural sort of (version) numbers within text

-w, --width=COLS
    assume screen width instead of current value

-x  list entries by lines instead of by columns

-X  sort alphabetically by entry extension

-Z, --context
    print any SELinux security context of each file

-1  list one file per line

--help
    display this help and exit

--version
    output version information and exit

SIZE is an integer and optional unit (example: 10M is 10*1024*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).
