    NAME
         ls - list contents of directory

    SYNOPSIS
         ls [ -acdfgiloqrstu1ACLFR ] name ...

    DESCRIPTION
         For each directory argument, ls lists the contents of the
         directory; for each file argument, ls repeats its name and
         any other information requested.  By default, the output is
         sorted alphabetically.  When no argument is given, the
         current directory is listed.  When several arguments are
         given, the arguments are first sorted appropriately, but
         file arguments are processed before directories and their
         contents.

         There are a large number of options:

         -l   List in long format, giving mode, number of links,
    	  owner, size in bytes, and time of last modification for
    	  each file.  (See below.) If the file is a special file
    	  the size field will instead contain the major and minor
    	  device numbers.  If the file is a symbolic link the
    	  pathname of the linked-to file is printed preceded by
    	  ``->''.

         -o   Include the file flags in a long (-l) output.

         -g   Include the group ownership of the file in a long out-
    	  put.

         -t   Sort by time modified (latest first) instead of by
    	  name.

         -a   List all entries; in the absence of this option,
    	  entries whose names begin with a period (.) are not
    	  listed.

         -s   Give size in kilobytes of each file.

         -d   If argument is a directory, list only its name; often
    	  used with -l to get the status of a directory.

         -L   If argument is a symbolic link, list the file or direc-
    	  tory the link references rather than the link itself.

         -r   Reverse the order of sort to get reverse alphabetic or
    	  oldest first as appropriate.

         -u   Use time of last access instead of last modification
    	  for sorting (with the -t option) and/or printing (with
    	  the -l option).

         -c   Use time of file creation for sorting or printing.

         -i   For each file, print the i-number in the first column
    	  of the report.

         -f   Output is not sorted.

         -F   cause directories to be marked with a trailing `/',
    	  sockets with a trailing `=', symbolic links with a
    	  trailing `@', and executable files with a trailing `*'.

         -R   recursively list subdirectories encountered.

         -1   force one entry per line output format; this is the
    	  default when output is not to a terminal.

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

         -q   force printing of non-graphic characters in file names
    	  as the character `?'; this is the default when output
    	  is to a terminal.

         The mode printed under the -l option contains 11 characters
         which are interpreted as follows: the first character is

         d	if the entry is a directory;
         b	if the entry is a block-type special file;
         c	if the entry is a character-type special file;
         l	if the entry is a symbolic link;
         s	if the entry is a socket, or
         -	if the entry is a plain file.

         The next 9 characters are interpreted as three sets of three
         bits each.  The first set refers to owner permissions; the
         next refers to permissions to others in the same user-group;
         and the last to all others.  Within each set the three char-
         acters indicate permission respectively to read, to write,
         or to execute the file as a program.  For a directory, `exe-
         cute' permission is interpreted to mean permission to search
         the directory.  The permissions are indicated as follows:

         r	if the file is readable;
         w	if the file is writable;
         x	if the file is executable;
         -	if the indicated permission is not granted.

         The group-execute permission character is given as s if the
         file has the set-group-id bit set; likewise the user-execute
         permission character is given as s if the file has the set-
         user-id bit set.

         The last character of the mode (normally `x' or `-') is t if
         the 1000 bit of the mode is on.  See chmod(1) for the mean-
         ing of this mode.

         When the sizes of the files in a directory are listed, a
         total count of blocks, including indirect blocks is printed.

    FILES
         /etc/passwd to get user id's for `ls -l'.
         /etc/group to get group id's for `ls -g'.

    BUGS
         Newline and tab are considered printing characters in file
         names.

         The output device is assumed to be 80 columns wide.

         The option setting based on whether the output is a teletype
         is undesirable as ``ls -s'' is much different than
         ``ls -s | lpr''.  On the other hand, not doing this setting
         would make old shell scripts which used ls almost certain
         losers.
