I once tested Mac OS X and something that called my atention was Automator, a software to visually create scripts to automatize tasks on the desktop. Is there any Linux alternative for this software?
There is Gnu Xnee, which enables you to record and replay actions on the desktop. You can install it from the software center.
"GNU Xnee is a suite of programs that can record, replay and distribute user actions under the X11 environment. Think of it as a robot that can imitate the job you just did."
If you're feeling adventurous, you could try out Sikuli. It's a computer-vision-based, cross-platform GUI automator with a slick IDE. It wasn't developed on Linux, so the Linux documentation is a little thin; however, it's pretty intuitive, and most of the non-Linux documentation applies.
xnee and its version with a GUI
You can find it in the software center or install it via
sudo apt-get install gnee
Screenshots and documentation are available on the GNU xnee page.
As a third solution, you can take the trip to the Java world by taking a look at Actions, which closely mimics Automator look and feel.
