Run parallel process and exit all if one fails

问题

I have this snippet of code, to start make t1 , make t2 and make t3 in parallel.

Is there a way to kill rest of the make processes when one fails? e.g, if make t2 fails, script should kill other 2 running (make t1 and make t3) and come out.

for ARG in '"t1" "t2" "t3"'
do
   cd ${ARG}
   make ${ARG} & pid=$!
   PID_LIST+=" $pid";
   cd -
done
trap "kill $PID_LIST" SIGINT
echo "Parallel makes have started $PID_LIST"
wait $PID_LIST

回答1:

With GNU Parallel

parallel --halt now,fail=1 'cd {}; make {}' ::: t1 t2 t3
