XFS_PROJID="$(awk -F= '/^add_grp_id=/{print $2}' <${SGE_JOB_SPOOL_DIR}/config)"
NB: If you want this on the slave node of a multi-node job and you allow
multi-node jobs to share nodes (we don't) then you will need to extract
a project id on each slave node. Probably the best place to do this
would be in a wrapper around rsh_daemon. However you'll need some sort of
locking in case a program launches multiple slave tasks(most codes
just launch one slave task per node which then forks) or launches
a slave task on the master node.
