What're some of the dumbest things you've done to yourself in Linux?
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 already posted this before but a friend did
chmod -R user /usr/binand broke every suid and guid bin including sudo lol.Personally have accidentally shadow deleted /home via an incorrect bind mount so I couldn't log into my own user.
I did something similar (that my professor still talks about in class as a cautionary tale)
I ran
chown -R user .*(intending to target all hidden files in the folder) and for people that don't know.*also matches..(..was/in this case) which changed the permissions on all files on the system to that user, including sudo.We fixed it by mounting the root of the file system in a docker container which effectively gave us root.
I've also been hit by
.*matching... First of all, I find this really really jarring. It makes sense and doesn't at the same time. I also wonder how to properly only glob the hidden files but I'm too afraid to experiment.
