问题
I want to automatically trigger a shell command when a file is modified. I think this can be accomplished in code by registering an inotify hook and call to system, however is there a higher level bash command that can accomplish this?
回答1:
Try inotify-tools. I'm having problems copying the link (sorry), but there is a wiki on GitHub which yu should be able to find with G-search-engine.

I don't have a solution to your problem, but I've found this nice program that you might use the feature you request: cwatch
