diff3
DIFF3(1) User Commands DIFF3(1)NAME
diff3 - compare three files line by line
SYNOPSIS
diff3 [OPTION]... MYFILE OLDFILE YOURFILE
DESCRIPTION
Compare three files line by line.
Mandatory arguments to long options are mandatory for short options too.
-A, --show-all
output all changes, bracketing conflicts
-e, --ed
output ed script incorporating changes from OLDFILE to YOURFILE into MYFILE
-E, --show-overlap
like -e, but bracket conflicts
-3, --easy-only
like -e, but incorporate only nonoverlapping changes
-x, --overlap-only
like -e, but incorporate only overlapping changes
-X like -x, but bracket conflicts
-i append 'w' and 'q' commands to ed scripts
-m, --merge
output actual merged file, according to -A if no other options are given
-a, --text
treat all files as text
--strip-trailing-cr
strip trailing carriage return on input
-T, --initial-tab
make tabs line up by prepending a tab
--diff-program=PROGRAM
use PROGRAM to compare files
-L, --label=LABEL
use LABEL instead of file name (can be repeated up to three times)
--help display this help and exit
-v, --version
output version information and exit
The default output format is a somewhat human-readable representation of the changes.
The -e, -E, -x, -X (and corresponding long) options cause an ed script to be output instead of the default.
Finally, the -m (--merge) option causes diff3 to do the merge internally and output the actual merged file. For unusual input, this is
more robust than using ed.
If a FILE is '-', read standard input. Exit status is 0 if successful, 1 if conflicts, 2 if trouble.
