diff3(1) General Commands Manual diff3(1)
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.
