send mail from linux terminal in one line
email, linux
Solution
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.
Problem
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 user@gmail.com [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.
