Man1 - ls.1

ls - list directory contents

ls [/OPTION/]… [/FILE/]…

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

list all entries in directory order

-F, –classify[=/WHEN/]

append indicator (one of */=>@|) to entries; WHEN can be ’always’ (default if omitted), ’auto’, or ’never’

–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 file system 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), width

*–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

–zero

end each output line with NUL, not newline

-1

list one file per line

–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.
