Shell script to send email
提问by
I am on linux machine and I monitor a process usage. Most of the time I will be away from my system and I have access to internet on my device. So I planned to write a shell-script that can mail me the output of the process.
我在 linux 机器上，我监视进程使用情况。大部分时间我都会离开我的系统，我可以在我的设备上访问互联网。所以我计划编写一个 shell 脚本，可以将过程的输出邮寄给我。
Is it possible?

Yes it works fine and is commonly used:
是的，它工作正常并且常用：
$ echo "hello world" | mail -s "a subject" [email protected]

Basically there's a program to accomplish that, called "mail". The subject of the email can be specified with a -s and a list of address with -t. You can write the text on your own with the echo command:
基本上有一个程序可以实现这一点，称为“邮件”。电子邮件的主题可以用 -s 指定，地址列表用 -t 指定。您可以使用 echo 命令自行编写文本：
echo "This will go into the body of the mail." | mail -s "Hello world" [email protected]
or get it from other files too:
或者也从其他文件中获取：
mail -s "Hello world" [email protected] < /home/calvin/application.log
mail doesn't support the sending of attachments, but Mutt does:
mail 不支持发送附件，但 Mutt 支持：
echo "Sending an attachment." | mutt -a file.zip -s "attachment" [email protected]
Note that Mutt's much more complete than mail. You can find better explanation here
请注意，Mutt 比邮件更完整。你可以在这里找到更好的解释

mail -s "Your Subject" [email protected] < /file/with/mail/content
(/file/with/mail/contentshould be a plaintext file, not a file attachment or an image, etc)
（/file/with/mail/content应该是纯文本文件，而不是文件附件或图像等）

Well, the easiest solution would of course be to pipe the output into mail:
好吧，最简单的解决方案当然是将输出通过管道传输到邮件中：
vs@lambda:~$ cat test.sh
sleep 3 && echo test | mail -s test your@address
vs@lambda:~$ nohup sh test.sh
nohup: ignoring input and appending output to `nohup.out'
I guess sh test.sh &will do just as fine normally.
我想sh test.sh &正常情况下会做得一样好。
