chgrp -- change group
chgrp [-fhvx] [-R [-H | -L | -P]] group file ...
The chgrp utility sets the group ID of the file named by each file oper-
and to the group ID specified by the group operand.
The following options are available:
-H If the -R option is specified, symbolic links on the command line
are followed and hence unaffected by the command. (Symbolic
links encountered during traversal are not followed.)
-L If the -R option is specified, all symbolic links are followed.
-P If the -R option is specified, no symbolic links are followed.
This is the default.
-R Change the group ID of the file hierarchies rooted in the files,
instead of just the files themselves. Beware of unintentionally
matching the ``..'' hard link to the parent directory when using
wildcards like ``.*''.
-f The force option ignores errors, except for usage errors and does
not query about strange modes (unless the user does not have
-h If the file is a symbolic link, the group ID of the link itself
is changed rather than the file that is pointed to.
-v Cause chgrp to be verbose, showing files as the group is modi-
fied. If the -v flag is specified more than once, chgrp will
print the filename, followed by the old and new numeric group ID.
-x File system mount points are not traversed.
The -H, -L and -P options are ignored unless the -R option is specified.
In addition, these options override each other and the command's actions
are determined by the last one specified.
The group operand can be either a group name from the group database, or
a numeric group ID. If a group name is also a numeric group ID, the op-
erand is used as a group name.
The user invoking chgrp must belong to the specified group and be the
owner of the file, or be the super-user.

The chgrp utility exits 0 on success, and >0 if an error occurs.
In previous versions of this system, symbolic links did not have groups.
The -v and -x options are non-standard and their use in scripts is not
