NAME
GNU 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.
