           **--time** =_WORD_
                  select which timestamp used to display or sort; access time

           **-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 directory entries
    
           **-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,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).
