In a script I have a variable containing the files that need to be attached to a single e-mail like:

$attachments=attachment_1.pdf attachment_2.pdf attachment_3.pdf attachment_4.pdf
Also a $templatevariable like:
还有一个$template变量，如：
$template="Subject: This is the subject
From: [email protected]
To: %s
Content-Type: text/plain
This is the body.
"
I have come up with:
我想出了：
printf "$template" "$recipient" |
sendmail -oi -t
Somewhere within this I must attach everything in the $attachmentsvariable?
在此范围内的某个地方，我必须附加$attachments变量中的所有内容？
