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.

Files
       /tmp/d3?????
       /usr/lib/diff3

NAME
diff3 - 3-way differential file comparison SYNOPSIS
diff3 [-exEX3] filename1 filename2 filename3 DESCRIPTION
diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes: ==== all three files differ ====1 filename1 is different ====2 filename2 is different ====3 filename3 is different The type of change suffered in converting 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. The following command will apply the resulting script to filename1. (cat script; echo '1,$p') | ed - filename1 OPTIONS
-e Produce a script for the ed(1) editor that will incorporate into filename1 all changes between filename2 and filename3 (that is, the changes that normally would be flagged ==== and ====3). -x Produce a script to incorporate only changes flagged ====. -3 Produce a script to incorporate only changes flagged ====3. -E Produce a script that will incorporate all changes between filename2 and filename3, but treat overlapping changes (that is, changes that would be flagged with ==== in the normal listing) differently. The overlapping lines from both files will be inserted by the edit script, bracketed by <<<<<< and >>>>>> lines. -X Produce a script that will incorporate only changes flagged ====, but treat these changes in the manner of the -E option. USAGE
See largefile(5) for the description of the behavior of diff3 when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes). FILES

Text lines that consist of a single `.' will defeat -e. Files longer than 64 Kbytes will not work. SunOS 5.10 14 Sep 1992 diff3(1)
