Where do I start?
GeekTool is an app for the Mac that allows you to display different kinds of information on your desktop. These bits of information are called Geeklets, and they can be text, images, files, and the output of shell commands.
1. Download GeekTool
The first thing to do is to download GeekTool from tynsoe.org, the website of Yann Bizeul who develops GeekTool.
2. Download Geeklets
This is where this site comes in. Ordinarily you tell GeekTool what to display using a complicated GeekTool command. To make things easier, collected here are Geeklets that have been contributed by users of the site. They are organised into categories according to their function. The collections category contains groups of Geeklets that go well together.
Once you have found a Geeklet that you like, just click the link below the description to download it. Once downloaded, simply double-clicking on it will open it up in GeekTool.There's no need to type in a complicated GeekTool command!
3. Make your own Geeklets
Once you are familiar with how GeekTool works, you might want to start creating your own Geeklets. The best way to start is by editing other peoples. Start by changing the fonts and colours, then try new commands and scripts. Before you know it, you'll be an expert!
Click the above screenshot to see a bigger version. GeekTool has been used to display the current date, the day's calendar events from iCal, a to do list, current unread mail messages and a list of running applications' CPU and memory usage. Each of these bits of information is a single Geeklet.
