Thanks! I find how to send mails from terminal!
This is copy paste from that what I find!
Code:
mail
The simplest way to send mail to someone with the username "someone" is to type:
> mail someone
You can mail to several different people at the same time by specifying several usernames, separated by spaces.
When the `mail' utility starts up, you will be prompted for a subject line. Once you provide one (and press the return key), you can enter your message. When you have finished the message, you can exit mail in one of two ways: by issuing the end-of-file character (Control-D); or by typing a period ('.') as the first character of the last line. When you exit, you will be prompted for 'Cc:', at which point you can enter any usernames you forgot to include in the original command line, or your own username (for your very own personal "carbon copy").
You can also use `mail' to read mail you have received. If you have received mail, you will be notified when you log in. You may then call up mail by entering
> mail
to read new incoming messages.
Reading old messages, stored in the file "mbox" in your home directory, is also easy:
> mail -f mbox
