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 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.
