Type man mail to see the basic documentation for the mail command. Here's a brief excerpt: When recipients are named, mail assumes a message is being sent. It reads from the standard input up to an end-of-file In a Unix shell, standard input normally comes from whatever you type at the terminal right after giving the command. But you can redirect a file to the standard input using the < symbol: mail address <filename. Now you just need to figure out how to set the ``Subject'' line to ``CS 221 Assignment #1''. Mike O'D.
