|
|
|

--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,R,Q (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.
|
|
|
|
The WHEN argument defaults to 'always' and can also be 'auto' or 'never'.
|
|
|
|
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(1) 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).
