# Command-line Notifier for OS X

# Add to your $PATH, chmod +x it, and then call it like so:
# notify.sh [-t "Title"] [-st "Subtitle"] [-s "Sound Name"] Text to display in notification

# I've tested it using BASH 4.3 (installed through MacPorts) and 3.2.57 (preinstalled with El Capitan), 
# and it worked fine with both
