问题描述

我的脚本有问题，由于启动脚本时指定的 IP 列表，我无法生成所有被 ping 的 IP 的 HTML 报告。 有人可以帮我吗，非常感谢您的帮助，这对于学校项目的顺利进行至关重要。

您的 html 有（至少）引用问题。 所有 " 将被 shell 删除。要保留 '"' 像这样逃脱它 \" 或用 ' 包围它

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）。

如需更多调试，请给我们更多信息。

使用 here doc 获取字符串而不处理替换。

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

我从您的评论中看到您的 sendmail 无法正常工作。 该命令本身似乎很好，并且可以在我的机器上运行。 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。 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。 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......
