You mean `qrsh` without a command? Then you get a plain new shell without any
environment variables set. Nevertheless you can use something like this in your
~/.profile:
# Number of necessary MYPARENT= commands depends on the startup method builtin
vs. SSH
MYPARENT=`ps -p $$ -o ppid --no-header`
#MYPARENT=`ps -p $MYPARENT -o ppid --no-header`
#MYPARENT=`ps -p $MYPARENT -o ppid --no-header`
MYSTARTUP=`ps -p $MYPARENT -o command --no-header`
if [ "${MYSTARTUP:0:13}" = "sge_shepherd-" ]; then
echo "Running inside SGE"
MYJOBID=${MYSTARTUP:13}
MYJOBID=${MYJOBID% -bg}
echo "Job $MYJOBID"
set -a
while read LINE; do export $LINE; done <
/var/spool/sge/${HOSTNAME%%.*}/active_jobs/$MYJOBID.1/environment
fi
Still the SGE_BINDING won't be set, maybe it's only added on-the-fly by the
shepherd. But as we know the path to the job's spool directory, we can look
into:
$SGE_JOB_SPOOL_DIR/pe_hostfile
where it's recorded in case you submit with `qrsh -binding pe linear:2` instead
of using the "env" binding_instance. (The pe_hostfile is always there, even for
a serial job. But $PE_HOSTFILE is only set for a parallel one.)
