Grsync is a GUI front end to rsync for your Gnome desktop. You can install Grsync by issuing the following command in Terminal:
sudo apt-get install grsync
Once installed, you will find Grsync listed under Applications > System tools.
If you are like me, this makes setting up rsync commands a lot easier. Now if I can just get a visual tool to show me wildcarding on-the-fly, I will have it made with my date commands.
