CHGRP(1)			   BSD General Commands Manual				 CHGRP(1)

NAME
     chgrp -- change group

SYNOPSIS
     chgrp [-R [-H | -L | -P]] [-fhv] group file ...

DESCRIPTION
     The chgrp utility sets the group ID of the file named by each file operand to the group ID
     specified by the group operand.

     Options:

     -H      If the -R option is specified, symbolic links on the command line are followed.
	     (Symbolic links encountered in the tree 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.

     -R      Change the group ID for the file hierarchies rooted in the files instead of just the
	     files themselves.

     -f      The force option ignores errors, except for usage errors and doesn't query about
	     strange modes (unless the user does not have proper permissions).

     -h      If file is a symbolic link, the group of the link is changed.

     -v      Cause chgrp to be verbose, showing files as they are processed.

     If -h is not given, unless the -H or -L option is set, chgrp on a symbolic link always suc-
     ceeds and has no effect.  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.
     Since it is valid to have a group name that is numeric (and doesn't have the numeric ID that
     matches its name) the name lookup is always done first.  Preceding the ID with a ``#'' char-
     acter will force it to be taken as a number.

     The user invoking chgrp must belong to the specified group and be the owner of the file, or
     be the super-user.

     Unless invoked by the super-user, chgrp clears the set-user-id and set-group-id bits on a
     file to prevent accidental or mischievous creation of set-user-id or set-group-id programs.

     The chgrp utility exits 0 on success, and >0 if an error occurs.

FILES
     /etc/group  Group ID file

SEE ALSO
     chown(2), lchown(2), fts(3), group(5), passwd(5), symlink(7), chown(8)

STANDARDS
     The chgrp utility is expected to be POSIX 1003.2 compatible.

     The -v option and the use of ``#'' to force a numeric group ID are extensions to IEEE Std
     1003.2 (``POSIX.2'').
