−3, −−easy−only
like −e, but incorporate only nonoverlapping changes
−x, −−overlap−only
like −e, but incorporate only overlapping changes
−X |

|||
−i |

−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.
