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 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 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.


/etc/group group ID file


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 recommended.
