Shell 脚本发送电子邮件

我在 linux 机器上，我监视进程的使用情况。大多数时候，我将远离我的系统，我可以访问我的设备上的互联网。因此，我计划编写一个 shell 脚本，它可以将进程的输出邮件给我。

有可能吗？

如果是这样，如何让一个 shell 脚本发送我的邮件？

请提供一个片段来开始。

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:

echo "This will go into the body of the mail." | mail -s "Hello world" you@youremail.com

or get it from other files too:

mail -s "Hello world" you@youremailid.com < /home/calvin/application.log

mail doesn't support the sending of attachments, but Mutt does:

echo "Sending an attachment." | mutt -a file.zip -s "attachment" target@email.com

Note that Mutt's much more complete than mail. You can find better explanation here

PS: thanks to @slhck who pointed out that my previous answer was awful. ;)

Yes it works fine and is commonly used:

$ echo "hello world" | mail -s "a subject" someone@somewhere.com

mail -s "Your Subject" your@email.com < /file/with/mail/content

(/file/with/mail/content should be a plaintext file, not a file attachment or an image, etc)

Well, the easiest solution would of course be to pipe the output into mail:

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.

top -b -n 1 | mail -s "any subject" your_email@domain.com

sendmail works for me on the mac (10.6.8)

echo "Hello" | sendmail -f my@email.com my@email.com
