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 ג€˜neverג€™, ג€˜alwaysג€™, or ג€˜autoג€™

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

-D, –dired
generate output designed for Emacsג€™ 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 ג€˜*ג€™

–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

-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 (donג€™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
ג€˜lsג€™ 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 ג€˜dateג€™; if FORMAT
is FORMAT1<newline>FORMAT2, FORMAT1 applies to non-recent  files
and FORMAT2 to recent files; if STYLE is prefixed with ג€˜posix-ג€™,
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 ג€˜-1ג€™, 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.
