uuencode是否可以使用and发送多个附件sendmail？
在一个脚本中，我有一个变量，其中包含需要附加到单个电子邮件的文件，例如：
$attachments=attachment_1.pdf attachment_2.pdf attachment_3.pdf attachment_4.pdf
还有一个$template变量，例如：
$template="Subject: This is the subject
From: no-reply@domain.com
To: %s
Content-Type: text/plain
This is the body.
"
我想出了：
printf "$template" "$recipient" |
sendmail -oi -t
在此的某个地方，我必须将所有内容附加到$attachments变量中？
uuencode附件并通过发送sendmail发送 MIME 附件更好。
uuencode在脚本中实现更简单，但通过电子邮件发送某些客户端不支持它。
attachments="attachment_1.pdf attachment_2.pdf attachment_3.pdf attachment_4.pdf"
recipient='john.doe@example.net'
# () sub sub-shell should generate email headers and body for sendmail to send
(
# generate email headers and begin of the body asspecified by HERE document
cat - <<END
Subject: This is the subject
From: no-reply@domain.com
To: $recipient
Content-Type: text/plain
This is the body.
END
# generate/append uuencoded attachments
for attachment in $attachments ; do
uuencode $attachment $attachment
done
) | /usr/sbin/sendmail -i -- $recipient
对于它的价值，mailx也很好用。
mailx -s "Subject" -a attachment1 -a attachement2 -a attachment3 email.address@domain.com < /dev/null
