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

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. 4th Berkeley Distribution October 21, 1996 EX(1)

	    [a-z]n yy	 Yanks n lines to the [a-z] buffer.  Default is current line.

	    [a-z]n p	 Puts n yanked text lines from the a-z buffer, after the cursor.

       Exiting vi

	    ZZ		 Exits and saves changes

	    :wq 	 Writes changes to current file and quits edit session.

	    :q		 Quits edit session (no changes made).

       The command uses all of the same edit or commands as However, does not allow you to write the file. See

Options
       -t tag	 Specifies a list of tag files.  The tag files are preceded by a backslash () and are separated by spaces.  The tag option should
		 always be the first entry.

       +command  Tells the editor to begin by executing the specified command.	A useful example would be +/pattern to search for a pattern.

       -l	 Sets the showmatch and lisp options for editing LISP code.

       -r name	 Retrieves the last saved version of the name'd file in the event of an editor or system crash.  If no file is specified,  a  list
		 of saved files is produced.

       -wn	 Sets  the default window size to n.  This option is useful for starting in a small window on dialups.	The -x option is available
		 only if the Encryption layered product is installed.

       -x	 Causes to prompt for a key.  The key is used to encrypt and decrypt the contents of the file. If  the	file  contents	have  been
		 encrypted with one key, you must use the same key to decrypt the file.

Restrictions
       Software tabs using ^T work only immediately after the autoindent.

       Left and right shifts on intelligent terminals do not make use of insert and delete character operations in the terminal.

       The  wrapmargin option sometimes works incorrectly because it looks at output columns when blanks are typed.  If a long word passes through
       the margin and onto the next line without a break, then the line is not broken.

       Insert/delete within a line can be slow if tabs are present on intelligent terminals, since the terminals need  help  in  doing	this  cor-
       rectly.

       Saving text on deletes in the named buffers is somewhat inefficient.

       The  source  command does not work when executed as :source; there is no way to use the :append, :change, and :insert commands, since it is
       not possible to give on a :global you must Q to command mode, execute them, and then reenter the screen editor with or
