  Or use /* for the path so it globs to all directories under / whilst not triggering the logic which requires –no-preserve-root.

    Yes, that’s how I nuked my workstation once. Part of my development routine was running sudo rm -rf $SDCARD/*. Guess what happens when SDCARD isn’t defined.

      set -u is your friend. Unless you’re running that command interactively, in which case it just exits the shell without giving any warning at all. Oh, the joys of shells written to be compatible with scripts created 20 years ago…

        It was interactive, but thanks, killing the shell is still better than reinstalling the machine.

    Shouldn’t it be /*.* for proper nuking or is that unnecessary ?
