Mini Notifier is a commandline tool to send notification to OS X notification center.
Build the program by running
make in the same directory as the
Makefile is at. The binary will be moved to the current directory,
and a script
notify.sh will be created. Copy this script to
somewhere in your
$PATH, and run it like you usually would with a
NSUserNotification and its friends require an application bundle.
So it is probably impossible to just write a “unix programm”.
