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.

      Sounds great in theory, but when you are trying to use awk to print out commands that might have something like printf and have to start escaping quotes, it gets really messy really quick. I have run into situations like this more than I care to as I like writing commands that will write out other commands. Spaces in filenames also mess with things like sed or sort where you want a specific column. Sorry, but in my opinion using the same character that was previously determined to be a delimiter is just a bad idea.
