You have (at least) quoting problem on your html.您的 html 有（至少）引用问题。 All " will be remove by the shell. To keep a '"' escape it like this \" or suround it by '所有 " 将被 shell 删除。要保留 '"' 像这样逃脱它 \" 或用 ' 包围它

If you just print your html on a terminal you will not see any " I think (not tested).如果您只是在终端上打印 html，您将看不到任何“我认为（未经测试）。

Use a here doc to get a string without processing substitutions.使用 here doc 获取字符串而不处理替换。

htmlsite=$(cat - <<EOF
<html lang="en">
...
</html>
EOF
)

I see from your comment that your sendmail is not working.我从您的评论中看到您的 sendmail 无法正常工作。 The command seems to be fine per se and it works on my machine.该命令本身似乎很好，并且可以在我的机器上运行。 Make sure that you can manually send messages out with that command: if not you need to troubleshoot your sendmail setup.确保您可以使用该命令手动发送消息：如果不能，您需要对 sendmail 设置进行故障排除。 Also your resultatping variable gets the output of your ping command but the result is sent to the file mail.txt without HTML: the variable htmlsite is never used.此外，您的resultatping变量获得 ping 命令的 output，但结果被发送到文件mail.txt而没有 HTML：变量htmlsite从未使用过。 Finally IMHO it's probably not a great idea to call a variable ping and use it as an argument for the ping command...最后恕我直言，调用变量ping并将其用作 ping 命令的参数可能不是一个好主意......
