diff3(1)							   User Commands							  diff3(1)

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

       /tmp/d3*

       /usr/lib/diff3prog

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+

       +-----------------------------+-----------------------------+

SEE ALSO

NOTES

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

       Files longer than 64 Kbytes will not work.
