NOTE: The four 'arrow' keys almost always work in 'command' or 'insert' mode.

The 'ed' editor.

The 'ed' editor is a line editor. Other than the fact that it is virtually guaranteed to be on any *nix computer, it

has no socially redeeming features, although some applications may need it. A _lot_ of things have been

offered to replace this 'thing' from 1975.

==> Emergency exit from 'ed'

1. type a period on a line by itself, and press <Enter> This gets you to the command mode or prints a line of

text if you were in command mode. 2. type q and press <Enter>. If there were no changes to the file, this

action quits ed. If you then see a '?' this means that the file had changed, and 'ed' is asking if you want to save

the changes. Press q and <Enter> a second time to confirm that you want out.

The 'pico' editor.

'pico' is a part of the Pine mail/news package from the University of Washington (state, USA). It is a very

friendly editor, with one minor failing. It silently inserts a line feed character and wraps the line when it

exceeds (generally) 74 characters. While this is fine while creating mail, news articles, and text notes, it is

often fatal when editing system files. The solution to this problem is simple. Call the program with the −w

option, like this:
