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.
Mounted root to a game folder on home and
sudo rm -rf ~/games/*because I accidentally copied the home folder into the games subvol which turned out to be the root subvol. Thanks btrfs!BTRFS: yo dawg, we heard you like partitions, so we put partitions in your partitions, so you can mount it inside your mounts.
I really like the idea of partitions without fixed sizes. I know it’s not the same but just as useful when you reinstall your system.
