I have a py script S1 that I would need to execute inside a screen. On an end-user point of view, I would like them to just execute another python script S2, which will open a screen and execute the script S1 inside that screen.
S2.py is like this :
import os os.cmd('echo Outside main terminal') os.cmd('screen -S sTest') os.cmd('echo I would like to be inside screen here. Not successfully!. How to send command to screen instead of remaining at main Terminal') os.cmd('spark-submit S1.py') #this should execute inside screen. currently main Terminal is the one that runs it #Additional steps to check status, clean up, check if screen is active then spawn another sTest2 sTest3, otherwise close and/or reuse screen sTest, etc. screen_list = os.cmd('screen -ls') if 'sTest' in screen_list ...... #let python process
What I want is that end-users can simply run
python S2.py, the screen hassle is handled by me at the back. I will need to have extra mechanism to clean up screen, use existing screens etc. Giving users instruction to open screen themselves will litter every terminal with screens.
S1.py needs to be inside screen is due to SSH connection stability if run on main Terminal.
