ed is a powerful text editor based on non-visual (line-oriented) behavior, originally written by the [research papers | http://www.superiorpapers.com/] of KenThompson for the early UnixOperatingSystem. Think of it as an ultimate form of non-WYSIWYG: instead of seeing some part of the text you're editing on the screen and making modifications into the seen version, you have separate commands for showing text, adding it, moving in it, changing it, and so on. The standard argument about vi, that you have to learn it anyway if you're going to rescue a Unix system sometime, applies double to ed: I remember some rescue disk with only ed, no vi. (Much in line with echo * as an ls replacement). As with vi, after some usage you might become quite fluent with ed.
