STYLE: full-iso, long-iso, iso,

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

-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.
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.
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).
