One of my colleagues managed to accidentally run something like rm -rf /var/tmp/ * on a Solaris machine that was the mail server for the entire organisation.

After the command finished they realised that the inadvertent space in front of the asterisk meant that the command did slightly more damage than intended.

They were told to leave the machine running to be able to fix it from a backup, but they rebooted instead.

An open file is still usable even after it's been deleted, so the kernel and shell were still up and running .. before the reboot ..

If I recall, it took weeks to fix, involving floppy disks, Sun engineers and much egg on face.

The rm command REALLY needs to have the -f flag changed edit: to mean "ignore write protection" not "go turbo fuckery mode"

[-] vk6flab@lemmy.radio 24 points 6 months ago

Yeah, except for root that is exactly how it works.

As root you are permitted to shoot your own foot and are expected to know how to aim.

[-] LodeMike@lemmy.today 3 points 6 months ago

Actually its the same as it overrides confirmation settings...

Remember kids, you gotta use rm -rf --no-preserve-root /* now a days!

[-] Barbarian@sh.itjust.works 47 points 6 months ago* (last edited 6 months ago)

rm -rf /* will work just fine (assuming sudo permissions ofc)

You need the additional flag for rm -rf --no-preserve-root /

[-] Kowowow@lemmy.ca 10 points 6 months ago

What is that for?

[-] ImplyingImplications@lemmy.ca 44 points 6 months ago

Too many people got trolled into "removing the French language pack" on Linux systems that there's now a check to see if someone is deleting every file off their computer (including the os system files). --no-preserve-root is the option you need to include to actually delete all the files off your system.

weird how it doesn't warn you for rm -rf /* though

[-] lseif@sopuli.xyz 8 points 6 months ago

depending on your shell, i believe the glob is expanded before it gets to the rm program

[-] wander1236@sh.itjust.works 30 points 6 months ago

Contrary to the memes, Linux does actually sometimes try to stop you from shooting yourself in the foot

[-] rtxn@lemmy.world 25 points 6 months ago

Yes, do as I say!

[-] LainTrain@lemmy.dbzer0.com 6 points 6 months ago

Every time I get one of these even if I 100% feel like I know what I'm doing it strikes a deep fear in me

Overrides the protection in place that prevents you from deleting the root of your filesystem.
