sudo - command line battle

This is not a game for the faint of heart, your command line skills will be put to the test in the ultimate shell game. There will be some cats involved, and you might get chown'd. You may need to grep the signal from the noise, cd into uncomfortable situations, and sometimes sed your way through consequences you can’t undo. Expect puzzles that don’t hold your hand, and a difficulty curve that chmods itself the longer you play. If you’re the type who treats the terminal as a playground or a proving ground, you’ll feel right at home. If you’re still looking for a tutorial that apologizes for being technical, this could be your exit. This game doesn’t nice itself for beginners. Bring your instincts and patience. Only the stubbornly clever need apply.
