|||
-i |

-m, --merge

-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

-v, --version

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.
