NAME

chgrp - change group  

SYNOPSIS

[-R [-H | -L | -P ] ] [-fh ] group files ...  

DESCRIPTION

The 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.

If -h is not given, unless the -H or -L option is set, on a symbolic link always succeeds 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. If a group name is also a numeric group ID, the operand is used as a group name.

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

Unless invoked by the super-user, 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 utility exits 0 on success, and >0 if an error occurs.
