diff3
diff3(1) General Commands Manual diff3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
file1 file2 file3
DESCRIPTION
compares three versions of a file, and prints disagreeing ranges of text flagged with these codes:
all three files differ
file1 is different
file2 is different
file3 is different
The type of change required to convert a given range of a given file to some other is indicated in one of these ways:
Text is to be appended after line number
n1 in file f, where f = or
Text is to be changed in the range line
n1 through line n2. If n1 = n2, the range can be abbreviated to n1.
The original contents of the range follows immediately after a indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Produces a script for the
editor that can be used to incorporate into file1 all changes between file2 and file3 (see ed(1)); i.e., the changes that
normally would be flagged and
Produces a script to incorporate only changes flagged
Produces a script to incorporate only changes flagged
Produces a script that will incorporate all
changes between file2 and file3, but treat overlapping changes (that is, changes that would be flagged with in normal
listing) differently. The overlapping lines in both files will be inserted by the edit script bracketed by and lines.
Produces a script that will incorporate only changes flagged
, but treat these changes in the manner of option.
The following command applies the resulting script to file1.
