Name
       ex, edit - text editor

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

Description
       The  editor  is	the  root  of a family of editors: and The editor is a superset of with the most notable extension being a display-editing
       facility.  Display-based editing is the focus of

       The name argument indicates the files to be edited.

Options
       -    Suppresses all interactive-user feedback.  This option is useful in processing editor scripts in command files.

       -v   Equivalent to using rather than

       -t   Equivalent to an initial tag command, that is, editing the file containing the tag and positioning the editor at its definition.

       -r   Used to recover after an editor or system crash.  It recovers by retrieving the last saved version of the named file.  If no  file	is
	    specified, it displays a list of saved files.

       -R   Sets the read-only option at the start.

       +command
	    Indicates  that  the editor should begin by executing the specified command.  If the command is omitted, it defaults to $, positioning
	    the editor at the last line of the first file, initially.  Other useful commands here are scanning patterns of the form  +/pattern	or
	    line numbers.

       -l   Sets up for LISP.  That is, it sets the showmatch and lisp options.  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 them.

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

       The command does not clear the buffer modified condition.

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

       File input/output errors do not print a name if the command line minus sign (-) option is used.

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

       The editor does not warn you if you place text in named buffers and do not use it before exiting the editor.

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

Name
       diff3 - 3-way differential file comparison

Syntax
       diff3 [-ex3] file1 file2 file3

Description
       The command compares three versions of a file, and publishes the ranges of text that disagree, flagged with the following codes:

	  ====	      all three files differ

	  ====1       file1 is different

	  ====2       file2 is different

	  ====3       file3 is different

       The type of change needed to convert a given range of a given file to some other is indicated in one of these ways:

	  f : n1 a    Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.

	  f : n1 , n2 c
		      Text is to be changed in the range line n1 to line n2.  If n1 = n2, the range may be abbreviated to n1.

       The original contents of the range follows immediately after a c indication.  When the contents of two files are identical, the contents of
       the lower-numbered file is suppressed.

Options
       -3   Produces an editor script containing the changes between file1 and file2 that are to be incorporated into file3.

       -e	   Produces an editor script containing the changes between file2 and file3 that are to be incorporated into file1.

       -x	   Produces an editor script containing the changes among all three files.

Examples
       Under the -e option, publishes a script for the editor that incorporates into file1 all changes between file2 and  file3  -  that  is,  the
       changes	that would normally be flagged ==== and ====3.	Option -x (-3) produces a script to incorporate only changes flagged ==== (====3).
       The following command applies the resulting script to `file1':
       (cat script; echo '1,$p') | ed - file1

Restrictions
       Text lines that consist of a single `.'	defeat -e.
