Run python commands in parallel in Linux shell scripting

Question

I have a script which gets input from the user through command line arguments. It processes the arguments and starts running python commands. For Example:

./run.         


        

Answer 1

Try running each process in the background by adding & to the end of the command.

python script1.py arg1 arg2 &
python script2.py arg1 arg2 &

echo "Running scripts in parallel"
wait # This will wait until both scripts finish
echo "Script done running"

Answer 2

Your task is not where GNU Parallel excels, but it can be done:

parallel ::: "python abc.py p1 p4" "python xyz.py p2 p3"
