XKCD 1168: - Rob, you use Unix! Come quick! * To disarm the bomb simply enter a valid "tar" command on your first try. No googling. You have ten seconds. * -

  That's just silly, though. "tar" is pretty easy to use in its basic form, and I have dozens of commands ingrained in my memory. tar tf filename.tar tar xf filename.tar tar xfz filename.tar.gz # Newer tars don't even require the z tar cfz filename.tar.gz directoryname Heck, surely even tar --help would suffice. More interesting questions would be like: "which lower-case letters are NOT valid options to GNU ls". :)

    I had untarred hundreds of files before I actually needed to start creating tar files on a regular enough basis to remember the syntax.
