Changing file attributes
************************

   A file is not merely its contents, a name, and a file type (Note:
Special file types).  A file also has an owner (a userid), a group (a
group id), permissions (what the owner can do with the file, what
people in the group can do, and what everyone else can do), various
timestamps, and other information.  Collectively, we call these a file's
"attributes".

   These commands change file attributes.

chgrp invocation
