diff3 -- 3-way differential file comparison

Synopsis

diff3 [-exEX3] file1 file2 file3

Description

diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:

====
all three files differ

====1
file1 is different

====2
file2 is different

====3
file3 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.


-e
Produce a script for the editor ed(1) that will incorporate into file1 all changes between file2 and file3, 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 file2 and file3, 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.

The following command will apply the resulting script to file1.

cat script; echo '1,$p') | ed - file1
