change the group ownership of a file
chgrp [-R] [-h] group file ...
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 have appropriate privilege 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 a privileged user can arbitrarily change owner IDs
whether this option is in effect or not.
chgrp has two options:
descends through the directory, and any subdirectories,
setting the specified group ID as it proceeds.
When symbolic links are encountered,
they are traversed.
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.
The LC_CTYPE environment variable determines the codesets
used in the arguments

This command has been updated to handle files greater than 2GB.
