What is meaning of bash command python3 ./deployment/generators/generatePKGlist.py --file app-pkg.yml

Question

I am trying to make sense of following line in one of the bash script

python3 ./deployment/generators/generatePKGlist.py --file app-pkg.yml

Specially, What is meaning of '--file app-pkg.yml' in above line?

Answer 1

It runs the python module and passes the --file as key and app-pkg.yml as the value of the file to that module(./deployment/generators/generatePKGlist.py) as a parameter for running the module.

Answer 2

It's running the python script generatePKGlist.py passing command line arguments --file app-pkg.yml.

As you tagged unix, having the corresponding shebang and correct execution permission on the file turns specifying the interpreter unnecessary.

Verify if the shebang is there or add it otherwise (first line)

#! /usr/bin/env python3

and

chmod +x ./deployment/generators/generatePKGlist.py

then you can just run

./deployment/generators/generatePKGlist.py --file app-pkg.yml
