Debian you have new mail

A classic!

In Debian, you can check for new mail by running the following command:

mail

This will open the mail program, which is a simple text-based email client. You can then use the following commands to navigate and read your email:

You can also use the less command to view the contents of a message:

less <message_number>

Replace <message_number> with the number of the message you want to view.

Note: If you have multiple email accounts set up on your system, you may need to specify the account you want to check by running mail -f <account_name>.
