When a file is saved I would like to set the file's group owner to an
environment variable. This is on a Linux box. I know that I can use
after-save-hook. I assume that I would have to call a shell command to do
this. I don't know how access an environment variable and call the chgrp
command from emacs. Any help would be appreciated.
