ed - line-oriented text editor
ed [
options] [
file]
GNU ed is a line-oriented text editor. It is used to create, display, 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most purposes, however, it is superseded by full-screen editors such as GNU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.

invalid input file, 3 for an internal consistency error (e.g., bug) which
caused ed to panic.
