是否可以通过非登录shell的单行命令从bash登录shell执行python脚本？

Question

I have a use case where I need to execute a Python script I'm working on from a login shell due to a dependency on values sourced from /etc/profile.d/. There's several combinations I've tried, but I seem to run into one issue or another.

This is nested in another automated process that's running in a non-login shell so I'm looking for a one-line command to get this to work.

Does anyone know of a one-line command to get this to work?

For example, I tried the following, but it failed with the "cannot execute binary file" error:

bash --login python my_python_script.py
/usr/bin/python: /usr/bin/python: cannot execute binary file

I've also tried a few other combinations with and without the shebang. Any help is appreciated.

You need -c there before the command and then you need to quote the command as a single argument.

bash --login -c 'python my_python_script.py'

If the shell also needs to be an interactive shell then the -i option needs to be used there also.

bash --login -i -c 'python my_python_script.py'
