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.
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
This is the scariest comment I’ve read in this thread.
Imagine that you’re using fqdns instead of ips…
I refuse to elaborate.
