Run python script after another running script ends
Question:
I have a python script running that will take a long time. I want to run another script immediately after the first finishes. It’s of no use to make a bash program to sequentially run the scripts because the first is already running.
How do I run some Python script after the one that is already running finishes?
PS the script that is running is running on a screen, and there could be more than one screen open.
Answers:
You could import the code from the second script, and run it at the end of the first one.
The first thing I thought of is running both Python programs from within a shell script so the 2nd one simply starts when the first one ends:
#!/bin/bash
python -m script1.py
python -m script2.py
If the first script is already running, or started outside of your control, you could use the ps command in a loop to detect when it finishes, and then launch the second the 2nd script:
#!/bin/bash
while [ 1 ]
do
cnt=`ps x | grep -v grep | grep -c script1.py`
if [[ "$cnt" -eq 0 ]]
then
break
fi
sleep 1
done
echo "Starting second program"
python -m script2.py
Tip: when using this approach, remember to use grep -v grep before the grep that looks for the process you want, or your grep command will count itself in the results.
