-C
list entries by columns

control whether color is used to distinguish file types. WHEN may be `never’, `always’, or `auto’

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

-N, –literal
print raw entry names (don’t treat e.g. control characters specially)

like -l, but do not list group information

-p, –file-type
append indicator (one of /=@|) to entries

-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)

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 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
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
show times using style STYLE: full-iso, long-iso, iso, locale, +FORMAT FORMAT is interpreted like `date’; if FORMAT is FORMAT1FORMAT2, 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

-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
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 following: 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 connected to a terminal (tty).
