Answer 2

You can also use sendmail:

/usr/sbin/sendmail user@domain.com < /file/to/send

Answer 3

mail can represent quite a couple of programs on a linux system. What you want behind it is either sendmail or postfix. I recommend the latter.

You can install it via your favorite package manager. Then you have to configure it, and once you have done that, you can send email like this:

 echo "My message" | mail -s subject user@gmail.com

See the manual for more information.

As far as configuring postfix goes, there's plenty of articles on the internet on how to do it. Unless you're on a public server with a registered domain, you generally want to forward the email to a SMTP server that you can send email from.

For gmail, for example, follow http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/ or any other similar tutorial.

Answer 4

echo "Subject: test" | /usr/sbin/sendmail user@domain.com

This enables you to do it within one command line without having to echo a text file. This answer builds on top of @mti2935's answer. So credit goes there.

Answer 5

You can install the mail package in Ubuntu with below command.

Answer 6

Setup an email server, if you are using gmail or smtp. follow this link. then use this command to send email.

In case you are using gmail and still you are getting some authentication error then you need to change setting of gmail:
