I accidentally untarred archive intended to be extracted in root directory, which among others included some files for /etc directory.
I went on to rm -rv ~/etc, but I quickly typed rm -rv /etc instead, and hit enter, while using a root account.


Just get a cli trash tool and alias it to rm.
That’s certainly something you can do! I would personally follow the recommendation against aliasing rm though, either just using the trash tool’s auto complete or a different alias altogether.
Reason being as someone mentioned below: You don’t want to give yourself a false sense of security or complacency with such a dangerous command, especially if you use multiple systems.
I liken it to someone starting to handle weapons more carelessly because the one they have at home is “never loaded.” Better safe than sorry.
I think this is the best approach. I’ve created a short alias for my trash tool and also aliased
rmto do nothing except print a warning. This way you train yourself to avoid using it. And if I really need it for some reason I can just type\rm.If you want to train yourself even more effectively you can also alias
rmto runslinstead :)
