     In addition to the name of each file, print the file type,
     permissions, number of hard links, owner name, group name, size in
     bytes, and timestamp (by default, the modification time).  For
     files with a time more than six months old or in the future, the
     timestamp contains the year instead of the time of day.  If the
     timestamp contains today's date with the year rather than a time
     of day, the file's time is in the future, which means you probably
     have clock skew problems which may break programs like `make' that
     rely on file times.

     For each directory that is listed, preface the files with a line
     `total BLOCKS', where BLOCKS is the total disk allocation for all
     files in that directory.  The block size currently defaults to 1024
     bytes, but this can be overridden (Note: Block size).  The
     BLOCKS computed counts each hard link separately; this is arguably
     a deficiency.

     The permissions listed are similar to symbolic mode specifications
     (Note: Symbolic Modes).  But `ls' combines multiple bits into the
     third character of each set of permissions as follows:
    `s'
          If the setuid or setgid bit and the corresponding executable
          bit are both set.

    `S'
          If the setuid or setgid bit is set but the corresponding
          executable bit is not set.

    `t'
          If the sticky bit and the other-executable bit are both set.

    `T'
          If the sticky bit is set but the other-executable bit is not
          set.

    `x'
          If the executable bit is set and none of the above apply.

    `-'
          Otherwise.

     Following the permission bits is a single character that specifies
     whether an alternate access method applies to the file.  When that
     character is a space, there is no alternate access method.  When it
     is a printing character (e.g., `+'), then there is such a method.
