A text editor is one of the most important tools you will use on a UNIX-based machine. For example, the settings for most programs and servers are held in text files. If you want to write your own programs, you will use a text editor to do this and writing web pages is also done in a text editor.

There are a number of text editors installed on the SUCS machines, some more powerful than others. It's probably best to try a few and find the one you like most.
