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.
Attempting to resize the system partition without backing the system up first (right after I spent the whole day setting everything up). Gparted failed, the system did not boot any more so I had to stay up the night to redo the whole setup. No personal data loss since the system was fresh, though.
Since I got into Linux via virtual machines and Raspberry Pi before using it as my daily driver, I made most of my stupid beginner mistakes (like changing permissions on systen files) where it did not really matter.
