Update hash if file last modification date has changed

[rdiez]

I have a large amount of data, where just a few files change every now and then.

It would be nice for rhash to store the "last modified" timestamp of all files, in order to update the hashes only of all those files that have been modified since the last time around.

It would also be nice if rhash deleted the hashes for those files which no longer exist.

Or is there a way to achieve that, maybe with an external script?

You should write your own script, for example in python. JSON and 'tab delimited' formats look convenient for storing timestamp along with path and file hash.

Use example from #109 and the test_rhash.py script as a starting point.

I forgot this GitHub issue. I have already written such a script, look here:

RDChecksum

I guess we could close this issue. There does not seem to be much interest in this kind of feature for RHash anyway.
