[alpine-aports] [PATCH] testing/inotify-tools-inc: new aport (with --include regex)

From: Stuart Cardall <developer_at_it-offshore.co.uk>
Date: Sun, 10 May 2015 21:46:06 +0000

This is inotify-tools patched to add --include & --includei regexes

I've been testing it watching for a specific file. The --exclude
regexes still work too.
