NAME
ex, edit - text editor
SYNOPSIS
ex [ - I [ - v I [ -t tag I [ -r I [ +command I [ -1 I name
edit [ ex options I
DESCRIPTION
Ex is the root of a family of editors: edit, ex and vi. Ex is a superset
of ed, with the most notable extension being a display editing
facility. Display based editing is the focus of vi.
If you have not used ed, or are a casual user, you will find that
the editor edit is convenient for you. It avoids some of the complexities
of ex used mostly by systems programmers and persons
very familiar with ed.
If you have a CRT terminal, you may wish to use a display based
editor; in this case see vi(l), which is a command which focuses on
the display editing portion of ex. Note that the ability to edit
encrypted files is present only in the domestic (U.S.) version of the
UNIX PC software.
DOCUMENTATION
The document Edit: A tutorial provides a comprehensive introduction
to edit assuming no previous knowledge of computers or the
UNIX system.
The Ex Reference Manual - Version 9.5 is a comprehensive and
complete manual for the command mode features of ex, but you
cannot learn to use the editor by reading it. For an introduction
to more advanced forms of editing using the command mode of ex
see the editing documents written by Brian Kernighan for the editor
ed; the material in the introductory and advanced documents
works also with ex.
An Introduction to Display Editing with Vi introduces the display
editor vi and provides reference material on vi. All of these documents
can be found in volume 2c of the Programmer's Manual. In
addition, the Vi Quick Reference card summarizes the commands
of vi in a useful, functional way, and is useful with the Introduction.
