I'm aware that it's beyond the scope of cel, but I'd use incron anyday for jobs like this.

Inotify is specific to Linux, while CEL isn't OS dependent.

Except if you account for the fact that some other UNIX-like OS do not use bash as /bin/sh.

You could even say that using bash as /bin/sh "is specific to Linux."

How to fix: /#!\/bin\/bash/s/bash/sh/

A better approach surely would be to wrap inotify/osx fsevents

That's what incron does...

I'm sure I've seen a nicely crossplatform command-line tool for this, but I can't seem to find it. The closest (by support for non-poll APIs) seems to be 'simplefilewatcher'[1], but that's just a C++ library.

incron, inotify, filewatcher[2], puncher[3], guard[4] are a bunch of existing ones, but they're all either not entirely functional cross-platform, or require some faffing with dependencies to get working.
