chgrp(1) (Essential Utilities) chgrp(1)
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.
