how to forbid a command without a permission I intended to delete all the backup files in a directory, so I was going to type `rm *~` in the terminal. Unfortunately, I hit the _Enter_ before hitting the _tilde_ and unhappy things happened. Although, I've recovered all deleted files I really don't want it to happen again. Could I forbid the execution of such a command unless being granted a permission, like that of a superuser?

I am not a fan of overriding built-in commands, but in my .bashrc (part of Tilde, my "dot files") I explicitly do this:


alias rm='rm -i';


This makes `rm` ask for permission before deleting. It has saved me a few times. You can always override with `rm -f`.
