bleachbit - weakish/cheat GitHub Wiki

BleachBit deletes unnecessary files to free valuable disk space. It can also reduce the size of browser profiles by organizing their sqlite databases using sqlite3's vacuum and reindex functions.

bleachbit --gui # GUI version, select items, preview, then clean
bleachbit -l # list avaiable items
bleachbit -p ITEM # preview
bleachbit -c ITEM # clean

You may need sudo for some items, for example:

sudo bleachbit -c system.rotated_logs
