Introduction

GeekTool takes his name from the fact it is a software used mainly by people often qualified as "geeks". The time passing by, I finally realized that those geeks from the beginning of GeekTool made so cool things with it that "noobs" (the opposite of geeks) wanted to use it as well.

With that experience in mind, I tried to make GeekTool 3 easier to use for everyone, and I hope that people from all horizons will find it useful and fun.

What is GeekTool ?

The main idea behind GeekTool is that I felt an empty desktop was a waste of space and that there was room here for informations I'd like to have quick access to.

With GeekTool, you can display on your desktop blocks of informations, called Geeklets.

Actually, there are 3 kinds of geeklet :

• File
• Shell
• Image

Each one displays different kind of informations, sharing the same principles :
Geeklets are ...

• ... displayed on the desktop, between finder icons and desktop picture (though, it can be set as "Keep on top"),
• ... contained in square frame on any screen, and will stick to that screen,
• ... visible on all spaces, you can thank apple to allow developers to hook on Spaces change,
• ... organized in groups, you can then choose to display or not each group,
• ... part of minimum one group named "Default Group",
• ... easy to export and share with friends.

Quick Start Guide

To Install GeekTool, simply open GeekTool.prefPane icon, the system will open System Preferences, and ask if you would like to install GeekTool for all users on the system or just the current one.

After that, the GeekTool settings window is opened and you can start to have fun with it.

The main area of the window shows you three kind of modules you can use. To create your first Geeklet, just pick Shell icon for example, and drop it somewhere on your desktop.

An empty black translucid area will sit on the desktop, with the inspector palette ready for you to configure this geeklet.

Set "date" or "ls" in the Command field, and the result should be displayed in the selected window.

You can then change text color & font, alignment, etc...

The Three Standard Plug-InsFile Plugin

If you like to know what is going on on your computer, this one is for you. It displays on your desktop live content of an arbitrary file. Its primary use is to monitor system log files like /var/log/system.log

Content is scrolling live with latest lines at the bottom. It handles log file rotation as well.

Shell Plugin

Maybe the most powerful one, it lets you display on your desktop the output of any unix shell command. If you are a command line addict, this one is for you. Looks at what people are doing with it (More references on the Wiki ).

It handles ANSI escape color sequences so you can put some color in your script and some good shell knowledge.

Lot of usage examples can be found in the forums

Image plugin

This one has been created to display graph issued from monitoring systems like MRTG or Cacti.

Beyond that simple image display, you can slideshow images from a folder (even pick random ones), or images from public webcams on internet.
