ex

EX(1)							      General Commands Manual							     EX(1)

NAME

       ex, edit - text editor

SYNOPSIS

       ex [ - ] [ -v ] [ -t tag ] [ -r ] [ +command ] [ -l ] name ...
       edit [ ex options ]

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  complexi-
       ties 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(1), which is a command which focuses on the
       display editing portion of ex.

DOCUMENTATION

       The document Edit: A tutorial (USD:14) provides a comprehensive introduction to edit assuming no previous knowledge  of	computers  or  the
       UNIX system.

       The  Ex	Reference Manual - Version 3.7 (USD:16) 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 (USD:15) introduces the display editor vi and provides reference material on vi.  In addition,
       the Vi Quick Reference card summarizes the commands of vi in a useful, functional way, and is useful with the Introduction.

FILES

       /usr/share/misc/exstrings	  error messages
       /usr/libexec/exrecover	     recover command
       /usr/sbin/expreserve	     preserve command
       /etc/termcap		describes capabilities of terminals
       ~/.exrc			editor startup file
       /tmp/Exnnnnn		editor temporary
       /tmp/Rxnnnnn		named buffer temporary
       /usr/preserve		preservation directory

SEE ALSO

       awk(1), ed(1), grep(1), sed(1), grep(1), vi(1), termcap(5), environ(7)

AUTHOR

       Originally written by William Joy
       Mark Horton has maintained the editor since version 2.7, adding macros, support for many unusual terminals, and other features such as word
       abbreviation mode.

BUGS

       The undo command causes all marks to be lost on lines changed and then restored if the marked lines were changed.

       Undo never clears the buffer modified condition.

       The  z  command	prints	a  number  of  logical rather than physical lines.  More than a screen full of output may result if long lines are
       present.

       File input/output errors don't print a name if the command line `-' option is used.

       There is no easy way to do a single scan ignoring case.

       The editor does not warn if text is placed in named buffers and not used before exiting the editor.

       Null characters are discarded in input files, and cannot appear in resultant files.
