You may want to create a launcher function for your calls to gp, and then
capture the return value with $?. So something like this:
PROC_LIST="xaa xab xac xad xae xaf"
function foo () {
gp -q < $1 > $1.results
echo "$1 finished: $?" >> process_log.txt
}
for X in $PROC_LIST; do
foo $X
done
In the above example, when gp exits the return value is captured and appended
to process_log.txt. By parameterizing your calls to 'gp' you can add logging or
pid tracking functionality specific to that one call. You can even create
temporary pid files for each one that you can then monitor externally.
Adjusting this to use parallel would probably give you a more robust solution.
