About the mail program

The mail program described here is known as mail (or ucb/mail) and is available on many systems. Some systems provide a similar mail program called mailx which is an improved version of mail. If necessary, use the command mailx instead of mail.

Most mail programs work in a similar manner, so you will find the information on using mail useful when you come to use some other mailer.
