May I suggest you use this alias:

alias rm='echo "Do not use the rm command, use mv instead.";rm'

Please note: The rm command is still there. If you replace the rm command 
with a mv command, you get a feeling of safety because you think your 
alias will prevent desasters. Then on another machine the alias doesn't 
exist and you do remove the files (been there, done that).

No, that doesn't work. An alias accepts no arguments. You would need a 
function instead. It looks like this:

movetotrash () { mv -i $1 $HOME/trash; }
