I have read many solutions in google but nothing is working for me. I am using Bash on my Ubuntu machine. here is sendmail part of my script.
我创建了一个磁盘清理脚本，清理后会发送一封状态电子邮件。现在，当我通过命令行运行它时，它可以完美执行，但是通过 cronjob 它无法发送状态邮件，但脚本运行良好。我已经在谷歌阅读了很多解决方案，但没有什么对我有用。我在我的 Ubuntu 机器上使用 Bash。这是我的脚本的 sendmail 部分。
export CONTENT="/root/cleanup/cleanup.htm"
export SUBJECT="Disk Space Clean Up Process : Completed @ $date_time"
(echo "Subject: $SUBJECT"
echo "`cat sendmail_list.txt`"
echo "MIME-Version: 1.0"
echo "Content-Type: text/html"
echo "Content-Disposition: inline"
cat $CONTENT
)|/usr/sbin/sendmail -t

Please add /usr/sbinbefore sendmail in sh file:
请/usr/sbin在sh文件sendmail前添加：
/usr/sbin/sendmail "[email protected]" < file.txt

You need a blank line between the message header and the body.
消息标题和正文之间需要一个空行。
{
echo "Subject: $SUBJECT"
echo "$(< sendmail_list.txt)"
echo "MIME-Version: 1.0"
echo "Content-Type: text/html"
echo "Content-Disposition: inline"
echo ""
cat $CONTENT
} | /usr/sbin/sendmail -t
A couple of other things:
其他几件事：
- you don't need a subshell here, so I changed the surrounding parentheses to braces
- since this is bash, there's a shorthand for
$(cat file)--$(< file)
- 这里不需要子shell，所以我将周围的括号更改为大括号
- 因为这是 bash，所以有一个简写
$(cat file)——$(< file)
