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.
Yeah at this point I’ve aliased ‘rm’ to nothing and exclusively use ‘trash’.
In the past I’ve aliased rm to a wrapper that showed PWD and the files to be affected, slept a couple seconds in case I wanted to abort, then shredded smaller files, rm’ed big files, or placed in a Trash dir for certain kinds of files (.conf, .cfg, etc).
I might try to find or rewrite it.
That sounds great but I don’t want to keep the ‘rm’ muscle memory in case I’m on another computer and delete something important. Having to use ‘trash’ instead makes you more conscious when it errors out.
