Getting wanted data from the 'top' command (Linux)

[DeaD_EyE]

It's cool to build own tools. Additionally you can explore linux and learn how to handle pathlib for example.

def lspids():
    pids = []
    for path in pathlib.Path('/proc').iterdir():
        if path.name.isdigit():
            pids.append(int(path.name))
    return pids

Now you can explore the subdirectories of pids in /proc.
