There was a problem hiding this comment.
The provided `su` command is incorrect because it uses `-s`, which changes the shell to `/bin/sh`. To execute Python directly from a file, use `'bash'` instead of specifying the shell separately.
Here's an optimized version:
```python
subprocess.run(
['su', '-c', f"exec(open('{exec_python_file}').read())", self.user],
text=True,
capture_output=True, **kwargs)This assumes that you are using Linux with Bash. If your system uses a different default shell, adjust the arguments accordingly.
