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