I just discovered this, thus don’t know a lot about it, but
notifyutil is a pretty cool command line utility in OS X. I know it exists in both Lion and Mountain Lion, not sure how long it’s been around before that.
What it does is tap into the system-wide
notifyd daemon, allowing you to post and receive notifications between multiple applications/scripts. From the man page:
notifyutil is a command-line utility for interacting with the notifyd(8) notification server. It may be used to post notifications, detect and report notifications, and to examine and set the state value associated with a notification key.
For a quick idea what it can do, pop open a terminal and run this:
notifyutil -1 neato && osascript -e 'say "wow, thats pretty cool"'
Then, open another window or tab (or even a different Terminal app) and run:
notifyutil -p neato
Wow, that is pretty cool.
-1 in the first command tells it to wait for a single notification. You can set that to any integer, or use
-w to wait indefinitely. I have some grand scripting ideas for this, but they’ll have to wait a bit. Nose to the grindstone, shoulder to the wheel and all of that.
