SYNOPSIS

       chown  [-Rcfv]  [--recursive] [--changes] [--help] [--ver-

       file...

DESCRIPTION

       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.
