growlnotify is a command-line tool to post Growl notifications. You can control all aspects of the notification within any boundaries set up in the Growl pane of System Preferences. It can be very useful in shell scripts.
- Step 1: Download the standard Growl package for your system
- Step 2: Open the disk image, go into the “extras” folder, and then into the growl notify folder, and run the .pkg file.
The Installer package for growlnotify is in the growlnotify folder in the Extras folder on the Growl disk image. Simply open the Installer package and follow the on-screen instructions.
You can read more on the Growl Notify Tool on the growl extras page.
It does note that you should not use growlnotify in your applications, because you should use their SDK instead.
