Hmm I thought you only spin once so thereβs 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.
Cowards version:
[ $[ $RANDOM % 6 ] == 0 ] && echo 'rm -fr /... you crazy dude? NO' || echo 'Keep your french language pack, you will need it'
Does "rm /" include external drives under /media/$USER/* or /run/media/ ?
Yes
Btrfs snapshots?
You're using btrfs on prod?!
Man, you're crazier than I thought... /s
Oh shit that was too controversial, wasnβt it? s/btrfs/ LVM/g
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.
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.
$ [ $[ $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).
yeah i meant fish
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?
the backup was connected via /media/backups so that's gone too!
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
that's like starting fires on random properties to make sure your firefighters stay on their toes
I vaguely remember reading a news story about a firefighter that did that a while ago.
Ferb, I know what we're gonna do today
Sure do! They're on the prod servers and were one of the first things deleted!
Not sure, do I?
Same.
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
Ultimate ergonomics at the cost of entry speed.
