ed n.
"ed is the standard text editor." Line taken from original the
Unix manual page on ed, an ancient
line-oriented editor that is by now used only by a few Real Programmers, and even then
only for batch operations. The original line is sometimes uttered
near the beginning of an emacs vs. vi holy war on Usenet, with the (vain) hope to quench the
discussion before it really takes off. Often followed by a
standard text describing the many virtues of ed (such as the
small memory footprint on a Timex
Sinclair, and the consistent (because nearly non-existent) user
interface).
