Start process after an other has finished

Hi guys,

I have a short question.
I would like to start a process after an other one finished. Are there some commands to do so?

The first process is a python script i’ve started with nohup. This script will take a while to finish. Thats why i would like to write a script, that starts an other script right after the first one has finished.

Is this possible? If possible I would prefer a script written in python or bash

thank you! :slight_smile:

nohup python somescript.py
python nextscript.py

Ah ok thats means i will write a script, which starts both yhe processe. Great idea thx

but what can I do if the first process is alreadz running?

Then you should go back to the beginning. :slight_smile:

If started in console then suspend it with ctrl z, check with jobs.

Then

fg %1; echo "do this after"

Where %1 is the job number.

please next time, post such questions to the correct forum:

The fairly common way to do this is to create some sort of semaphore
(say, create a temp file in /var/run while the first process is running;
at the end of the first script, remove the semaphore file) and then in
the second process, include a check to see if the semaphore file exists,
and if it does, either exit or loop back, delay, and check again.
