Wag

This is half a bleg and half an idea.

Trying to get useful information of log files that are being continually written is kind of frustrating. The usual Linux method is to tail -f the file and then apply a bunch of grep, cut, sed or awk filters to the pipeline. This is clumsy if you don't know what you're dealing with or looking for yet, and there are a bunch of other limitations with this approach. So my idea is to create an application with these features:

I'm thinking it should be named 'wag', because it's the wag tailing the dog and because of a similarity to watch.

If such a thing even vaguely exists, please email me. Otherwise I'll have to think about learning how to write inotify-based ncurses-driven applications in my copious free time.
