Bash 如何使用fgrep | sed递归删除目录中的字符串

我有一个shell脚本：

#! /bin/bash

clear

REPLACE=""

fgrep -rl $SEARCH . | xargs sed -i 's/$SEARCH/$REPLACE/g'

fgrep -rl $SEARCH .

echo "Finished replacements"

我要做的是搜索一个字符串，实际上是恶意代码，然后使用fgrep和sed将其删除。我知道fgrep-rl$SEARCH可以工作，并返回包含该字符串的所有文件。但它也返回shell脚本。下面是一个列表，其中包含一些符合搜索条件的文件

./wp-includes/js/heartbeat.min.js
./wp-includes/js/crop/cropper.js
./wp-includes/js/thickbox/thickbox.js
./wp-includes/js/admin-bar.min.js
./findandreplace.sh

另一件事是sed部分有问题，因为它返回了一些错误：

在此之后，将修改脚本：

fgrep -rl $REPLACE . | xargs sed -i 's/$REPLACE/$REPLACE/g'

fgrep -rl $REPLACE .

所以实际上有三个问题：

脚本与搜索条件匹配（如何排除它？）

如何正确使用grep和sed

我想剧本是自己修改的

---

希望我说得够清楚。谢谢=）

也许这样更改脚本会对您有所帮助

for i in $(fgrep -rl --exclude='*.sh' $REPLACE .); do sed -i "s|${SEARCH}|${REPLACE}|g" "$i"; done;

---

在这里，我使用了

--exclude

从目标搜索中排除shell脚本，然后在for循环中运行它，这样我们就可以捕获每个文件名并替换搜索到的材料。

因此，这将非常复杂，因为您的搜索文本除了位于多行之外，还包含正则表达式中的特殊字符（例如

*

）以及引号。如果您没有从哲学上致力于使用bash和sed，那么下面是一些有用的方法：

在@miken32的回答之后，由于我对php比较熟悉，我最终得出以下结论：

但我没试过，所以我不确定

从这种恶意软件中恢复的更好方法是使用备份，但在我的情况下，这是不可能的，所以我选择了搜索/替换策略

谢谢你的帮助
 你能从搜索中排除$0吗？我不明白@miken32从搜索中排除$0是什么意思？？？$0指的是脚本的名称，所以排除它而不是所有的*.sh文件。运气不好，我得到的是：grep:var:没有这样的文件或目录grep:0xf19b=[“\x6F\x6E\x6C\x6F\x61\x64”、“\x67\x65\x74\x61\x74\x65”，“\x73\x65\x74\x44\x61\X64\x65”、“\x63\x6F\x6F\x6B\x69\x65”、“\x3D”、“\x3B\x20\x65\x78\x70\x69\x72\x65\x73\x3D”、“\x74\x6F\x55\x54\x43\x53\x74\x72\x69\x6E\x67”、“、”、“\x3D\x28:没有此类文件或目录“其他内容”这是：grep://*236499a9e0b11c0dc3eecf5cf751a097*/：没有这样的文件或目录sed:-e expression#1，char 38:unterminated
