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.
This happened just this morning. Probably not the dumbest thing ever, and I blame Snap for putting things where they don’t belong: I deleted stuff from the /run/user/1000/doc directory. Turns out the files there are in fact hard links to files which actually reside somewhere else. Well, they were, until I deleted them forever.
Background: Firefox (as an Ubuntu snap package) downloads files in some kind of sandbox mode and references stuff there for some obscure reason. That was my weekly reminder to get rid of snap packages because snap sucks in a myriad of ways.
snap has made df and mount frustrating as hell to use!!
