diff3 - compare three files line by line
diff3 [OPTION]... MYFILE OLDFILE YOURFILE

Mandatory arguments to long options are mandatory for short options

like -e, but incorporate only overlapping changes
-X like -x, but bracket conflicts
-i append 'w' and 'q' commands to ed scripts
output actual merged file, according to -A if no other options
treat all files as text
strip trailing carriage return on input
make tabs line up by prepending a tab
use PROGRAM to compare files
use LABEL instead of file name (can be repeated up to three
--help display this help and exit
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 inter-
nally 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.
