Question

I am calling a python script from within a shell script. The python script returns error codes in case of failures.

How do I handle these error codes in shell script and exit it when necessary?

Answer 1

The exit code of last command is contained in $?.

Use below pseudo code:

python myPythonScript.py
ret=$?
if [ $ret -ne 0 ]; then
     #Handle failure
     #exit if required
fi
