使用sed替换多个文件中的多行

Question

我有成千上万个html文件，其中有两个不同的旧Google adsense代码，需要用新代码替换。 这些文件位于Linux服务器上。

旧代码如下：

  <script type="text/javascript"><!--
google_ad_client = "pub-xxx";
google_ad_width = 336;
google_ad_height = 280;
google_ad_format = "336x280_as";
google_ad_type = "text";
//2007-06-09: Forum archive rectangle
google_ad_channel = "1013717472xx";
google_color_border = "FFFFFF";
google_color_bg = "FFFFFF";
google_color_link = "0000FF";
google_color_text = "000000";
google_color_url = "000000";
//-->
</script>
<script type="text/javascript"
  src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

我需要在代码中匹配此文本“ google_ad_channel =“ 1013717472xx”“，并用新代码替换整个代码。

新代码如下：

<script src="https://pagead2.googlesyndication.com/pub-config/r20160913/ca-pub-xxx.js"></script><script src="http://pagead2.googlesyndication.com/pub-config/r20160913/ca-pub-xxx.js"></script><script type="text/javascript"><!--
google_ad_client = "pub-xxx";
/* frm arch linkunit 200x90, created 5/30/08 */
google_ad_slot = "0112084554";
google_ad_width = 200;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

如何使用sed替换服务器上所有html文件？

先感谢您！
