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.


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 :)
