NAME

chgrp − change the group ownership of a file

SYNOPSIS

chgrp [ −f ] [ −R ] group-filename...

DESCRIPTION

chgrp changes the group ID (GID) of the filenames given as arguments to group. The group may be either a decimal GID or a group name found in the GID file, /etc/group. 

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

OPTIONS

−f Force.  Do not report errors. 

−R Recursive.  chgrp descends through the directory, and any subdirectories, setting the specified GID as it proceeds.  When symbolic links are encountered, their group is changed, but they are not traversed.
