From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What're some of the dumbest things you've done to yourself in Linux? (lemmy.ca)

I'm working on a some materials for a class wherein I'll be teaching some young, wide-eyed Windows nerds about Linux and we're including a section we're calling "foot guns". Basically it's ways you might shoot yourself in the foot while meddling with your newfound Linux powers.

I've got the usual forgetting the . in lines like this:

$ rm -rf ./bin

As well as a bunch of other fun stories like that one time I mounted my Linux home folder into my Windows machine, forgot I did that, then deleted a parent folder.

You know, the war stories.

Tell me yours. I wanna share your mistakes so that they can learn from them.

Fun (?) side note: somehow, my entire ${HOME}/projects folder has been deleted like... just now, and I have no idea how it happened. I may have a terrible new story to add if I figure it out.

I tried upgrading instead of a fresh install.

Needless to say, I ended up doing a fresh install eventually...

I footgunned myself with iptables once and couldn't even google how to fix it. (Well, I could with my phone, just not the convenient google - copy - paste - run workflow)

I don't remember the details, but I was trying to control internet access of a VM guest and ended up controlling my own too.

Mine was wiping my vps while backing it up. Luckily for me I only lost some files that I could easily replace.

I once had grub and rEFInd installed on the same system and an Arch update hosed both. I was able to fix it with an Ubuntu LiveCD and went back to Ubuntu. I still use Arch in a VM as a treat.

One time on Manjaro i had a dependency issue regarding python3. So i just removed it. The I watched in horror as i saw what packages depend on python3, including pacman and manjaro-system, but did not dare to interrupt the process and end up with a half-broken system, and my curiosity wanted to see it play out. Then I rebooted, and thus legally turned my Manjaro system into a half-working Arch install. It even displayed the OS as Arch Linux. Still managed to fix it without reinstalling by downloading the package files from http mirrors, but if i was smart the entire thing should have taken 5 minutes instead of a full afternoon. Was a valuable learning experience tho
