NAME
       ls - list directory contents


SYNOPSIS
       ls [OPTION]... [FILE]...

DESCRIPTION
       List  information  about the FILEs (the current directory by default).

       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

     print octal escapes for nongraphic characters

       --block-size=SIZE
     use SIZE-byte blocks

       -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

       -C     list entries by columns

       --color[=WHEN]
     control  whether color is used to distinguish file types.  WHEN
     may be ‘never’, ‘always’, or ‘auto’

     ence symbolic links

       -D, --dired
     generate output designed for Emacs’ dired mode

       -f     do not sort, enable -aU, disable -lst

       -F, --classify
     append indicator (one of */=>@|) to entries

       --file-type
     likewise, except do not append ‘*’

       --format=WORD

     like -l --time-style=full-iso

       -g     like -l, but do not list owner

       -G, --no-group
     like -l, but do not list group

       -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 direc-
     tory

       --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
     with -l, print the index number of each file

       -I, --ignore=PATTERN
     do not list implied entries matching shell PATTERN

       -k     like --block-size=1K

       -l     use a long listing format

       -L, --dereference
     when showing file information for a symbolic link, show informa-
     tion  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  spe-
     cially)

       -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
     with -l, print size of each file, in blocks

       -S     sort by file size

       --sort=WORD
     extension -X, none -U, size -S, time -t, version -v, status -c,
     time -t, atime -u, access -u, use -u

       --time=WORD
     with -l, show time as WORD instead of modification time: atime,
     access,  use, ctime or status; 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

       -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. In combination
     with one_per_line format ‘-1’, it will  show  files  immediately
     and it has no memory limitations.

       -v     sort by version

       -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

       -1     list one file per line

       SELinux options:

       --lcontext
     Display  security context.    Enable -l. Lines will probably be
     too wide for most displays.

       -Z, --context
     Display security context so it fits on most displays.   Displays
     only mode, user, group, security context and file name.

       --scontext
     Display only security context and file name.

       --help display this help and exit

       --version
     output version information and exit

       SIZE  may  be (or may be an integer optionally followed by) one of fol-
       lowing: kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T,
       P, E, Z, Y.

       By  default,  color is not used to distinguish types of files.  That is
       equivalent to using --color=none.  Using the --color option without the
       optional WHEN  argument is  equivalent to using --color=always.  With
       --color=auto, color codes are output only if standard  output  is  con-
       nected  to  a  terminal (tty). The environment variable LS_COLORS can
       influence the colors, and can be set easily by the dircolors command.

       Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.
