diff3

DIFF3(1)						      General Commands Manual							  DIFF3(1)

NAME

       diff3 - 3-way differential file comparison

SYNOPSIS

       diff3 [ -ex3 ] 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.

       Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3,  i.e.
       the  changes  that  normally  would  be	flagged ==== and ====3.  Option -x (-3) produces a script to incorporate only changes flagged ====
       (====3).  The following command will apply the resulting script to `file1'.

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

FILES

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

SEE ALSO

       diff(1)

BUGS

       Text lines that consist of a single `.' will defeat -e.
       Files longer than 64K bytes won't work.
