LS(1)                     BSD General Commands Manual                    LS(1)
NAME
     ls -- list directory contents

SYNOPSIS
     ls [-ABCFGHLOPRSTUW@abcdefghiklmnopqrstuwx1] [file ...]

DESCRIPTION
     For each operand that names a file of a type other than directory, ls displays its name as well as any
     requested, associated information.  For each operand that names a file of type directory, ls displays
     the names of files contained within that directory, as well as any requested, associated information.

     If no operands are given, the contents of the current directory are displayed.  If more than one oper-
     and is given, non-directory operands are displayed first; directory and non-directory operands are
     sorted separately and in lexicographical order.

     The following options are available:

     -@      Display extended attribute keys and sizes in long (-l) output.

     -1      (The numeric digit ``one''.)  Force output to be one entry per line.  This is the default when
             output is not to a terminal.

     -A      List all entries except for . and ...  Always set for the super-user.

     -a      Include directory entries whose names begin with a dot (.).

     -B      Force printing of non-printable characters (as defined by ctype(3) and current locale settings)
             in file names as \xxx, where xxx is the numeric value of the character in octal.

     -b      As -B, but use C escape codes whenever possible.

     -C      Force multi-column output; this is the default when output is to a terminal.

     -c      Use time when file status was last changed for sorting (-t) or long printing (-l).

     -d      Directories are listed as plain files (not searched recursively).
