Script to remove trailing tilde (~) from temporary files opened with kate

Using kate as text editor, temporary files that have been saved present an annoying trailing tilde that personally I consider useless. I'm used to be careful when I use something like text editor (good vim school!). So I realized this mini script in bash to remove temporary files when I've just saved the final document.

#!/bin/bash
rm `find $1 | grep '~$'`

The file above I've called rmm (I don't say why) and I'm put it in /usr/bin/

After written and saved something, I only open a shell, go to source directory and run this command:

$ rmm .

Or run directly this command without moving to source directory:

$rmm /home/matteo/src

This script is trivial and can be obviously improved. If you want to contribute I will be happy to add your le improvement.
