CHOWN(1)                         User Commands                        CHOWN(1)

NAME
       chown - change file owner and group

SYNOPSIS
       chown [OPTION]... [OWNER][:[GROUP]] FILE...
       chown [OPTION]... --reference=RFILE FILE...

DESCRIPTION
       This manual page documents the GNU version of chown.  chown changes the
       user and/or group ownership of each given file.  If only  an  owner  (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 owner  is
       followed  by  a  colon  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 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 and group are given, but the
       owner is omitted, only the group of the files is changed; in this case,
       chown  performs  the same function as chgrp.  If only a colon is given,
       or if the entire operand is empty, neither the owner nor the  group  is
       changed.
