Hello, is there any way to execute a command every time a "folder changes status"?
Under windows there's an API which pro-actively tells you when something has changed within a directory, so I was trying to achieve something similar under Linux.
I can't think anything else other than check the list of files and parameters (e.g. date/size/owner) every few seconds, but that's not ideal of course... So what I'm asking here is: is there is a way to set linux to tell me rather than me go and check?

I hope my question makes sense :-p

Cheers

Have a look at inotify and FAM.

From your own code use inotify - from a script use inotify-tools; you can wait on file(s) or directory(s).
I believe tail has been recently rewritten to use inotify rather than polling.
