Apparently, Prism Launcher chose to adhere to the idiotic principle of the hidden “trashbin”, .Trash-$(uid), invented by Ubuntu. Even though it’s based on QT. This can’t be disabled. It accumulated 139 GB of literal Trash, fully replaceable, over time. Just … why? There’s even an open issue about this, for over a year, referenced multiple times. I guess I have another point on my agenda.

  • I use command trash-empty to empty all trashcan of all the users, after each system update. It’s a non standard program, but most likely available in your distributions repository: https://github.com/andreafrancia/trash-cli And my alias/function will show each file that is about being deleted (just put it in .bashrc, if you have installed trash-cli, which includes trash-empty):

    old function (click to expand)
    empty() {
        echo "Files to delete:"
        trash-empty -f --dry-run |
            awk '{print $3}' |
            grep -vF '/info/'
        echo
        trash-empty
    }
    

    Edit: After I posted I just realized there is a more straightforward way of doing it:

    New and more simple alias:

    alias empty='trash-empty -f --dry-run ; trash-empty'
    

    This searches all trash cans, lists all files it has found to be deleted, then lists all directories it looked under and then asks if you want really delete. With trash-empty -f it deletes without asking.
