     SYNOPSIS
          chown [-Rcfv] [--recursive] [--changes] [--help] [--version]
          [--silent] [--quiet] [--verbose] [user][:.][group] file...

     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 chown.  chown
          changes the user and/or group ownership of each given file,
          according to its first non-option argument, which is
          interpreted as follows.  If only a user name (or numeric
          user ID) is given, that user is made the owner of each given
          file, and the files' group is not changed.  If the user name
          is followed by a colon or dot and a group name (or numeric
          group ID), with no spaces between them, the group ownership
          of the files is changed as well.  If a colon or dot but no
          group name follows the user name, that user is made the
          owner of the files and the group of the files is changed to
          that user's login group.  If the colon or dot and group are
          given, but the user name is omitted, only the group of the
          files is changed; in this case, chown performs the same
          function as chgrp.
