CHGRP(1)		     General Commands Manual			CHGRP(1)

NAME
     chgrp -- change group

SYNOPSIS
     chgrp [-fhvx] [-R [-H | -L | -P]] 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.

     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 proper
	     permissions).

     -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  modified.
	     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 operand
     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.

     If chgrp receives a SIGINFO signal (see the status argument  for  stty(1)),
     then  the	current filename as well as the old and new group names are dis-
     played.

FILES
     /etc/group  group ID file

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

COMPATIBILITY
     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 rec-
     ommended.

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

STANDARDS
     The chgrp utility is expected to be IEEE Std 1003.2 ("POSIX.2") compatible.
