send mail from linux terminal in one line
I know there is the command mail in linux to send emails via command line. How can I send an simple email with one line from the terminal though?
For example:
mail [email protected] [subject] [body]
And have the email sent without any confirmation or prompts to the user?
The reason is, I want to send a brief message via email to myself when a specific event happens in a java program. The idea is that I will use Runtime.getRuntime()… etc. to send the mail command from my java program.
I used cron to do something similar in the past, but the current implementation doesn't use cron, so I need to try this out instead.

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 [email protected]
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.
