DIFF3(C) XENIX System V DIFF3(C)
Name
diff3 - Compares three files.
Syntax
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 range 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. The -x option produces a script to
incorporate changes flagged with ``====''. Similarly, the
-3 option produces a script to incorporate changes flagged
with ``====3''. The following command applies a resulting
editing script to file1:
(cat script; echo '1,$p') | ed - file1
