Unowned __pycache__ directories can accumulate on Arch Linux, especially from tools installed via AUR.To find and clean up these directories, a script can be used to identify unowned __pycache__ directories.The script searches the system for __pycache__ directories excluding certain paths like Flatpak and checks ownership.By running this script, users can efficiently identify and remove unowned __pycache__ directories, maintaining system cleanliness.
