Lmao: Command Line Russian Roulette For Linux and Unix Users

Posted: 09 May 2017 11:21 AM PDT

Russian Roulette is a fatal game of chance in which a player places a single round in a revolver, spins the cylinder, places the muzzle against their head, and pulls the trigger.

Command line Russian Roulette for Linux and Unix system

Of course, you can play such game on your Linux or Unix server too (don’t run the following commands on your PC/MacOS/Unix/Linux system as it will delete everything):

[ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo *Click*
OR
[ $[ $RANDOM % 6 ] == 0 ] && rm -rf --no-preserve-root / || echo *Click*

Above shell kung-fu deletes all your files one out of six times. Hence, you must not run it in production. Here is a safe version:
[ $[ $RANDOM % 6 ] == 0 ] && echo '*Oh nooo*' || echo '*Click*'
