Question

If I want to call another batch script from within a batch script I could use

CALL File.bat

to pause the execution of the current batch file and wait for the CALLed script to complete.

I can use

START File.bat

if I want them to run simultaneously.

How do I achieve this behavior in a shell script??

Answer 1

If you want to wait:

#!/bin/bash
# do some stuff
/path/to/other/script
# do other stuff

To run it simultaneously (i.e. “in the background”):

#!/bin/bash
# do some stuff
/path/to/other/script &
# do other stuff, then optionally:
wait
# this will wait for all background jobs to finish

There are other ways, and certain things you should consider about input and output redirection for the background process if you want to provide specific input and/or capture output or errors, but that’s the basics.
