If I'm remembering correctly - the historical way to
do this is to alias the "rm" command to something that
else that checks the arguments and complains appropriately
(and then executes /bin/rm.) Typically with just a shell
alias. That keeps you from accidently doing something.
Just thinking that putting extra "smarts" into a utility
isn't the typical "UNIXy" way to do this. Let each tool
do the one thing it does really well.. 'rm' removes; let
I think, in the old "UNIX Review" magazine (what - almost
15+ years ago now?) There was a couple of examples of this.
