## rcsdiff

    rcsdiff [options] [diff_options] files

Compare revisions via diff. Specify revisions using -r as follows:

Number of Revisions specified: | Comparison made:
--- | ---
None | Working file against latest revision
One | Working file against specified revision
Two | One revision against the other

rcsdiff accepts the standard options -q, -V, and -x, as well as `diff_options`, which can be any valid diff option. rcsdiff exits with a status of 0 (no differences), 1 (some differences), or 2 (unknown problem).

### Options

-k`c`

  When comparing revisions, expand keywords using style `c`. (See co for values of `c`.)

-r`R1`

  Use revision `R1` in the comparison.

-r`R2`

  Use revision `R2` in the comparison. (-r `R1` must also be specified.)
