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.
Running the right command on the wrong SSH session/machine.
This is the scariest comment I’ve read in this thread.
Imagine that you’re using fqdns instead of ips…
I refuse to elaborate.
I set a different background color on all my machines because of exactly this while using VNC/RDP
this. after i set different zsh themes on my servers + my main machine i now know exactly what machine i’m running commands to
Neat idea, I hope I’ll remember this when I’m setting up my next server.
You are not alone.
Me every single day
