modify and otherwise manipulate text files, both interactively and
via shell scripts. A restricted version of ed, red, can only edit
files in the current directory and cannot execute shell commands.
Ed is the "standard" text editor in the sense that it is the original
editor for Unix, and thus widely available. For most purposes,
however, it is superseded by full-screen editors such as GNU Emacs
or GNU Moe.
