send mail from linux terminal in one line
提问by cHam
I know there is the command mailin linux to send emails via command line. How can I send an simple email with one line from the terminal though?
我知道maillinux 中有通过命令行发送电子邮件的命令。但是，如何从终端用一行发送简单的电子邮件？
For example:
例如：
mail [email protected] [subject] [body]
And have the email sent without any confirmation or prompts to the user?
是否在没有任何确认或提示的情况下向用户发送了电子邮件？
The reason is, I want to send a brief message via email to myself when a specific event happens in a javaprogram. The idea is that I will use Runtime.getRuntime()… etc. to send the mail commandfrom my javaprogram.
原因是，当java程序中发生特定事件时，我想通过电子邮件向自己发送一条简短的消息。这个想法是我将使用Runtime.getRuntime()...等mail command从我的java程序中发送。
I used cronto do something similar in the past, but the current implementation doesn't use cron, so I need to try this out instead.
我过去曾经cron做过类似的事情，但当前的实现不使用cron，所以我需要尝试一下。

mailcan represent quite a couple of programs on a linux system. What you want behind it is either sendmailor postfix. I recommend the latter.
mail在 Linux 系统上可以代表相当多的程序。您想要的是sendmail或postfix。我推荐后者。
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:
你可以通过你最喜欢的包管理器安装它。然后你必须配置它，一旦你完成了，你可以像这样发送电子邮件：
echo "My message" | mail -s subject [email protected]
See the manual for more information.
有关更多信息，请参阅手册。
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.
就配置 postfix 而言，互联网上有很多关于如何进行配置的文章。除非您在具有注册域的公共服务器上，否则您通常希望将电子邮件转发到可以从中发送电子邮件的 SMTP 服务器。
For gmail, for example, follow http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/or any other similar tutorial.
例如，对于 gmail，请遵循 http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/或任何其他类似教程。

You can use an echo with a pipe to avoid prompts or confirmation.
您可以使用带有管道的 echo 来避免提示或确认。
echo "This is the body" | mail -s "This is the subject" [email protected]

echo "Subject: test" | /usr/sbin/sendmail [email protected]
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.
这使您可以在一个命令行中完成此操作，而无需回显文本文件。这个答案建立在@mti2935 的答案之上。所以信用就在那里。
