Grep并用特殊字符替换文本

Question

我有10K + XML，其中大约一半具有我要替换的以下代码行：

<protocol_name_from_source><![CDATA[This section will be completed when reviewed by an Expert Review Panel.]]></protocol_name_from_source>

与此：

<protocol_name_from_source><![CDATA[Not applicable.]]></protocol_name_from_source>

我已经成功grep处理了受影响的文件： grep -rl '<process\_review><\!\[CDATA\[<p>The Expert Review Panel has not reviewed this measure yet\.<\/p>\]\]><\/process\_review>' ./

但是我似乎无法用sed替换文本：

grep -rl '<process\_review><\!\[CDATA\[<p>The Expert Review Panel has not reviewed this measure yet\.<\/p>\]\]><\/process\_review>' ./ | xargs sed -i 's/<process\_review><\!\[CDATA\[<p>The Expert Review Panel has not reviewed this measure yet\.<\/p>\]\]><\/process\_review>/<process\_review><\!\[CDATA\[<p>Not applicable\.<\/p>\]\]><\/process\_review>/g'

提前感谢您的帮助。

edit：这些XML在git repo中。有损坏回购协议的风险吗？

Answer 1

嗯，根据我的手册页，sed -i选项后面应加上一个（最终为0长度）扩展名。如果命令选项不是唯一的命令参数，则应在命令选项中加上-e。

所以我在这里用：

grep -rl '<process\_review><\!\[CDATA\[<p>The Expert Review Panel has not reviewed this measure yet\.<\/p>\]\]><\/process\_review>' ./ | xargs sed -i '' -e 's/<process\_review><\!\[CDATA\[<p>The Expert Review Panel has not reviewed this measure yet\.<\/p>\]\]><\/process\_review>/<process\_review><\!\[CDATA\[<p>Not applicable\.<\/p>\]\]><\/process\_review>/g'

当心，我还没有审查（long ...）sed s/.../.../命令...
