       chgrp - change file group

       chgrp [ -fR ] group file...

       The command changes the group ID of one or more files or directories.  For file, you may specify either a full or partial path.	For group,
       you may specify either a decimal GID or a group name found in the group file.

       The user entering the command must either be the superuser, or be the owner of the file and belong to the specified group.

       -f   Inhibits display of errors that are returned if fails to change the group identifier of a file.

       -R   Causes to recursively descend any directories subordinate to file and to set the specified	group for  each  file  encountered.   When
	    symbolic links are encountered, changes the group identifier of the link file but does not traverse the path associated with the link.

       Change group to admin for filea and fileb:
       chgrp admin filea fileb

chgrp -- change group SYNOPSIS
chgrp [-fhv] [-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: -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 the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed). -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. -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. Use -h to change the group ID of a symbolic link. -R Change the group ID for the file hierarchies rooted in the files instead of just the files themselves. -v Cause chgrp to be verbose, showing files as the group is modified. 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. DIAGNOSTICS
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 option is non-standard and its use in scripts is not recommended. FILES
/etc/group group ID file SEE ALSO
chown(2), fts(3), group(5), passwd(5), symlink(7), chown(8) STANDARDS
The chgrp utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. BSD
