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.

Using sudo when it isn't necessary, and the real cannon: sudo su.. Adding sudo to your command lines indiscriminately causes files you create to be owned by root even though they are in your home directory, and then you end up using sudo to make changes to the files... and then the filesystem permissions cannot prevent you from successfully running an accidental "sudo rm -rf /" command.
Seriously... sudo is not a "habit" to develop in order to avoid dealing with filesystem permissions problems.
this one used to fuck me up sooooo much.
I regularly find myself trying to tweak some system config and opening the file read-only because I forgot to
sudo vimit.Doesn't help that my everyday user account doesn't have sudo privileges, so I need to
suto my admin account first.
