How to replace a text in a shell executable file (.sh) using Python?

Question

I have xxx.sh file which content is:

setsid ./start-meteor.sh >> /home/farah/StudioInstallation/Studio/bricks/platform/log/databricksastro.log 2>&1 < /dev/null &

I want to change the above content to something like:

setsid ./start-meteor.sh >> /home/rose/validation/Studio/bricks/platform/log/databricksastro.log 2>&1 < /dev/null &

I need a Python code to do so.

You can call your python script as any name as you like, say search_replace.py

#!/usr/bin/env python3
import fileinput
import re

for line in fileinput.input(inplace=1, backup='.bak'):
         line = re.sub('farah/StudioInstallation','rose/validation', line.rstrip())
         print(line)

run this script and pass your filename that is xxx.sh as an argument,

$python search_replace.py xxx.sh
