Installing watch on mac

Download the “watch” command from Terminal.app
We are using “curl” a command line “broswer”
curl -O http://ktwit.net/code/watch-0.2-macosx/watch

Make “watch” executable
By doing this we tell Mac OS that this is a program that can run
chmod +x watch

Test the program
Let’s make sure everything is in working order.
./watch

Install “watch”
Optional: By following this next step we are placing watch into a system location that will allow you to run it from any location in the Terminal (You will be prompted for your password)
sudo mv watch /usr/bin/
