如何使用sed替换以下文本? [英] How to replace the following text using sed?

问题描述

我想替换 document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/脚本%3E"));

与

(function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;ga.src = ('https:' ==document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);})();

在所有情况下...

所以我使用了下面的代码.

So i used this below code.

find /cygdrive/c/xampp/htdocs/news -type f -exec sed -i s#document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));#(function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);})();#g {} \;

但它并没有取代.逃跑有问题吗?

But it is not replacing. Is there any problem in escaping ?

谢谢

推荐答案

您需要引用 sed 的参数，并转义任何嵌套的引号.否则这个:

You need to quote the argument to sed, and escape any nested quotes. Otherwise this:

s#document.write(unescape("%3Cscript src='" + gaJsHost +  ...

将被 shell 分解成单独的单词，而不是作为单个参数传递给 sed.

will be broken into separate words by the shell, instead of being passed as a single argument to sed.

您需要用引号将整个 sed 脚本(s#from#to# 部分)括起来，我会选择单引号，然后替换每个 ' 中的带有 \' 的脚本.

You need to surround the entire sed script (the s#from#to# part) in quotes, I would choose single quotes, then replace every ' in the script with \'.

(另外，你为什么使用 find -exec 而不是我建议的?)

(Also, why are you using find -exec instead of what I suggested?)
