root shell? Already playing it fast and loose, I see.
- The only legitimate commands for a non-root shell are sudo -i, exit, and echo "yee haw"
  
  yee haw

Fun fact there was a guy a little over a decade ago who got drunk and traded 7m barrels of oil futures. Not dollars, barrels. He made the price of oil jump up for a short while.
https://www.theguardian.com/business/2010/jun/29/drunk-oil-trader-banned-fsa
- Funnier Fact: they had to stack all those barrels behind the corporation's building until they could sell them all.
  ::I made this up::
  
  the best source
  
  Does that butt have any other fun facts up there?
  
  Actually a oil future is basically a promise to make oil for a certain price. There are also are vegetable futures
  That means the oil wasn't produced yet
- Well he was 69% of all traded volume..... nice!!
  
  Isn't that wild?

This really isn't dangerous unless you already screwed up badly. If it wipes, you just restore from backup/DR.
You do have backups and a DR plan for your prod servers, right?
- Same.
- Didn't some company have a script running that would randomly kill stuff to always test redundancies?
  I vaguely recall someone telling me that about netflix
  Edit: https://github.com/Netflix/chaosmonkey
  
  that's like starting fires on random properties to make sure your firefighters stay on their toes
- Sure do! They're on the prod servers and were one of the first things deleted!
- the backup was connected via /media/backups so that's gone too!
- Not sure, do I?

I did this once on my laptop with no backups. I was lucky. I also used the correct version with --no-preserve-root.

Obligatory --no-preserve-root
- Modern distros today. SMH. Back in my day everyone had root at the office.
  
  On ye olde hpux this would work, especially when you did rm-fr /$var and $var was unset and nobody unit tested their shell back then. That db server ran for 2 days though with open file handles before it finally died.

Given that their hand is over the mouse and not the keyboard/enter key, I assume they're gonna click close on the terminal :p
- Right click for paste, they have \n in the clipboard
  
  Afaik \n may not run a command. I have pasted multiline commands but they only seem to run after hitting enter
- Well they did have the type the command, and to do that they would first have to navigate to the terminal (assuming the machine isn't running just a plain tty) first.

change it to != cowards!

There is a $[]?
- Huh, it's the same as $(( )) - arithmetic expansion.
  I think it's deprecated and not in the bash manual, but it still seems to work.
  
  It is? Weird. I know about deprecated backticks, but this... I guess it's so deprecated that very few people know about this. Now a bit more.
  
  Its deprecated kinda like `` should be $() https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xcu_chap02.html seach for arithmetic expansion or $[].

Cowards version:
bash

[ $[ $RANDOM % 6 ] == 0 ] && echo 'rm -fr /... you crazy dude? NO' || echo 'Keep your french language pack, you will need it'

undefined

HISTCONTROL=ignorespace unset RANDOM RANDOM=4 clear ...
If RANDOM is unset, it loses its special properties, even if it is subsequently reset.
HISTCONTROL If the list of values includes ignorespace, lines which begin with a space character are not saved in the history list.
RTFM can save your server AND your bet ;-)
it is cheating of course if the predefined rules tell us about such requirements and if these are not met any more when unsetting RANDOM ahead of it.

This is why you use virtual machines, anyone can be root!
- We are root!
- Or just to have a modular, secure and private system.

What is right clicking on terminal going to do?
- maybe they have it mapped to enter, you never know with laptop linux users.
  
  Right click increase the temp of the touchpad, which the user has macroed as an "Enter"input, letting him press enter with all fingers on home row and just resting the palm on the touch pad

Btrfs snapshots?
- You're using btrfs on prod?!
  Man, you're crazier than I thought... /s
  
  Oh shit that was too controversial, wasn’t it? s/btrfs/ LVM/g

in 2024 this should rewrite history in all your githib repos to destroy wverything next fetch

Jokes on you, I use zsh, your silly bashisms have no power here.
- Are you sure it doesn't work on zsh? It's valid POSIX shell code, and like bash, zsh is a superset of POSIX, at least if I remember correctly.
  This is not to goad you into destroying your filesystem. Replace the rm with something relatively harmless like echo "BANG! You're dead!" if you decide to test it.
  
  Key here is the outer [] and interaction of $[], test doesn't have == by default in standard posix, so no this isn't posix shell or bourne compatible. Tis but another bashism. I could probably force zsh into a more bourne mode to try it but its definitely not portable bourne shell its bash.
  undefined
  
  $ [ $[ $RANDOM % 6 ] == 0 ] && echo rm || echo ok zsh: = not found $ zsh --version zsh 5.9 (x86_64-pc-linux-gnu)
  == should be -eq for this to be posix/bourne portable, you could use = but -eq is for numeric comparisons so not quite right.
- fish and nu are the superior shells
  
  Is fash like that fish shell only more fetch? zsh is obviously the best, its the omega end to shell names with the z (in latin alphabets so there).

Does "rm /" include external drives under /media/$USER/* or /run/media/ ?
- Yes

Hmm I thought you only spin once so there’s eventually a guaranteed shot. The 6 should decrement after each execution.
- That's not how randomness works. You would want to randomize once, saving the number of steps remaining until the bullet is the next shot, decrementing the number of steps for each try.

Truly the "Linux Roulette".
