Isn't the trash a feature of the Gnome GUI, not the shell? Using "rm" has always scared me, so I've recently configured my system thus:
Install trash-cli. See http://code.google.com/p/trash-cli/ Alias "del" to trash-put. <http://code.google.com/p/trash-cli/>Set a cron job to clean trash after xxx days. You probably could alias rm to trash-put, but trash-put doesn't support all the flags of rm and this would be uncharted waters...
