change the group ownership of a file
From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.
With the coreutil package (with the extra set), see chgrp(1) instead.
NAME
chgrp - change the group ownership of a file
SYNOPSIS
chgrp [-R] [-h] group file ...
DESCRIPTION
chgrp changes the group ID of the files given as arguments to group. The group may be either a decimal group ID or a group name found in the group ID file, /etc/group. You must be the owner of the file, or be the super-user to use this command. The operating system has a configuration option {_POSIX_CHOWN_RESTRICTED}, to restrict ownership changes. When this option is in effect, the owner of the file may change the group of the file only to a group to which the owner belongs. Only the super-user can arbitrarily change owner IDs whether this option is in effect or not. chgrp has one option:
-R Recursive. chgrp descends through the directory, and any subdirectories, setting the specified group ID as it proceeds. When symbolic links are encountered, they are traversed.
-h If the file is a symbolic link, change the group of the symbolic link. Without this option, the group of the file referenced by the symbolic link is changed.
FILES
/etc/group

NOTES
In a Remote File Sharing environment, you may not have the permissions that the output of the ls -l command leads you to believe. For more information see the Network User's and Administrator's Guide.
