At the UNIX shell prompt, type mm in lower case.
$ mm
If you type capital MM, you will get an error message. No harm is done, but nothing happens:
$ MM ksh: MM: not found $
When MM starts up, the screen clears and it displays a message like this:

The very first time you use MM, there is one extra step. MM will ask whether to create the file named mbox, where your mail will be kept. Respond to the question by typing y for yes, as shown here:
