      On modern Linux system yes but old Unix servers (or even recent?) would run it no problem

      Edit: It was initally introduced by sun microsystems in 2005 and was later adopted by GNU

      Sun Microsystem didn’t introduce it in 2005, rather it simply disallowed rm -rf / altogether

      Later GNU introduced --preserve-root and after that made --preserve-root the default and added --no-preserve-root https://en.wikipedia.org/wiki/Rm_(Unix)

      And also a short delay before printing ‘lucky boy’ so you can’t tell if it’s deleting everything or if it’s the built in delay.

        Oh I do remember that sickening feeling when an rm doesn’t come back immediately –_—

          I still remember when I managed to rm -rf / foo (I accidentally typed a space between / and foo) on my very early linux box on the 90s. 80486, 16 mb

          I pressed enter. Saw what I did. Remembered that sync ran at every 30s* Pressed the power button.

          *= those were simple times, but not better times

          So I rm -rf ed my root fs and my box survived it due to the quick power off.

      In my limited knowledge it randomly generates a number and if this number can be cleanly divided by 6 it deletes everything on the system (and the system itself). If not it prints ‘lucky boy’.

      So basically the nerd version of russian Roulette. But with higher stakes

        But with higher stakes

        I see you haven’t been converted to believe in the afterlife. Restoring from backup.

          If the backup is on the same device, it’s not a backup, and if you’ve not tested it on a clean machine, it’s not a backup.

            Also, if you’re not willing to actually use it to restore from backup, it’s not a backup. I remember once I fucked up surgery on the prod db (we didn’t have a testing db…) and was like, ok well at least we can just try again.

            Boss man was like “no! We can’t restore from backup, people will lose 1 hour of their work!!!” I spent 7 days writing a script to surgically fix my surgery instead. I had to fudge and guess some of the data but wcyd

      It’s a bash command that generates a random number. If that number divides by six with no remainder then it deletes everything on the server, if not it prints “lucky boy”. “Prod” servers are production servers, the ones the actual business runs on, as opposed to test or dev servers which are often deleted and rebuilt as developers to see if things work or not.

      This is Russian roulette for IT people to see if they destroy the running server or not

        generates a random number. If that number divides by six with no remainder

        Meaning a 1 in 6 chance, just like playing traditional Russian roulette with a revolver

        EDIT: For fun, here is a Russian roulette bash script that doesn’t actually do anything other than simply print pass or fail with a 1 in 6 chance:

        [ $[ $RANDOM % 6 ] == 0 ] && echo fail || echo pass;

      They’re basically playing Russian Roulette with their servers. They condition a remove all command on a random numbers generator and pray. If it does not wipe the server, it spits out “Lucky Boy”

    1. I’d hope that one’s production server is backed up.

    2. $ alias rm="echo Lucky boy"; clear

      “Okay, ready to play.”
