Bash Question

Run python commands in parallel in Linux shell scripting

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.sh p1 p2 p3 p4
python abc.py p1 p4
python xyz.py p2 p3


where
p1
,
p2
,
p3
and
p4
can be of any type.

I need to run both of these python commands in parallel and in two different terminals. How can I do it so that I don't need to wait for 1 command to finish in order to start the next command?

I tried GNU parallel but it doesn't seem to work.

Answer

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

python abc.py p1 p4 &

python xyz.py p2 p3 &
