     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of logname.
          logname prints the calling user's name, as found in the file
          /etc/utmp, and exits with a status of 0.  If there is no
          /etc/utmp entry for the calling process, logname prints an
          error message and exits with a status of 1.

        OPTIONS
          --help
               Print a usage message on standard output and exit
               successfully.

          --version
               Print version information on standard output then exit
               successfully.
