Using Wikipedia from the Linux command line
If you are sitting in front of a Linux system, you can always pop open a browser and query topics of interest on Wikipedia. On the other hand, if you’re logged on through a terminal emulator like PuTTY or you just prefer using the command line, there is another option: wikit.
Wikit is a tool that queries Wikipedia from the command line and provides summaries of its content on a huge collection of topics. It's easy to use and allows you to quickly query and, if you want, save the rendered information in a file.
How to use wikit
One of the things Wikipedia will not, at least currently, tell you about is wikit itself. So, this post will provide information on the command and show you how you can use it.
