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.
