A.10.1 diff options

These standard options are supported by diff (see section A.5 Common command options, for a complete description of them):

-D date
Use the most recent revision no later than date. See ‘-r’ for how this affects the comparison.
-k kflag
Process keywords according to kflag. See section 12 Keyword substitution.
Local; run only in current working directory.
Examine directories recursively. This option is on by default.
-r tag
Compare with revision tag. Zero, one or two ‘-r’ options can be present. With no ‘-r’ option, the working file will be compared with the revision it was based on. With one ‘-r’, that revision will be compared to your current working file. With two ‘-r’ options those two revisions will be compared (and your working file will not affect the outcome in any way). One or both ‘-r’ options can be replaced by a ‘-D date option, described above.

Additional options can be used to specify the format of the output, with the same meaning as in GNU diff. For a complete list of these options see section H Diff format options.
