I’ll give this (periodically md5sum files in a dir) a try, thanks! Does fam do anything different?
fam is a set of C functions. Apparently, you have to write C to use them, but you can call FAMMonitorDirectory() on a particular dir, then if anything changes in that dir or dirs below it, you get an event on a file descriptor. The details are all available in "man fam" if you have fam installed.
This is not a very friendly way to do things. I'm surprised no one's written a wrapper around it that makes it easier to use, but then, you usually don't actually need this and it can get very expensive.
