send mail from linux terminal in one line [closed]
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.comSee 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, followhttp://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/or any other similar tutorial.
