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.

Not too long ago, on a Slackware box I needed to manually change glibc to another version. No problem, I thought, just remove the version that's there and install the package for the version I needed. So removepkg glibc and then immediately dawned on me.... oh wait I really didn't want to do that... Of course, after that installpkg and pretty much everything else was broken since pretty much everything either depends on glibc, or has a dependency that depends on glibc, so I couldn't install the new package or do pretty much anything other than smack my forehead.

Wasn't actually too big of a deal to fix. Used another computer to create a bootable USB stick with the Slackware installer, booted the computer with the USB stick, and did some chroot trickery to reinstall the old glibc package again. Then booted it back up normally and used upgradepkg to change glibc like I should have in the first place.
