递归多行替换:更改版权标题 [英] Recursive multi-line replace: changing copyright headers

问题描述

我正尝试用新版本替换项目中的所有版权标头(超过100个文件).目前，每个文件的开头都有这样的内容:

I'm retrying to replace all of the copyright headers in my project (100+ files) with a new version. Currently I have something like this at the start of each file:

<?php
/**
 * Project name
 *
 * @copyright Apache 2.0
 * @author    FooBar
 */

我希望我的所有文件都这样开始:

And I want all my files to start like this:

<?php
/**
 * Copyright 2014 FooBar
 *
 * Licensed under the Apache License, Version 2.0 (the "License");
 * you may not use this file except in compliance with the License.

我已经看过了:

• this thread, which I can't get working. It does a partial replacement, keeping certain lines of the original text in the new text. I want a complete replacement.

此脚本，同样不适用于我的用例.它将每个文件的开头替换为新的标头，这将导致现有内容(<?php/** */)附加到新注释中，从而导致解析错误./p>

this script, which similarly doesn't work for my use case. It replaces the very start of each file with a new header, which causes the existing content (<?php /** */) to be appended to the new comment, thereby causing parse errors.

有人知道我可以如何替换递归多行文件吗?我需要使用sed/awk吗?

Does anybody know how I can do a recursive multi-line file replace? Do I need to use sed/awk?

解决方案:

我只需要执行以下bash脚本即可:

I just need to execute this bash script:

INPUT=../path

find $INPUT -name "*.php" -exec sed -i -e '2,/\*\//d; 1r copyright.txt' {} \;

推荐答案

假定所有文件均以

<?php
/**

如果是这样，您可以使用

If so, you can use

sed '2,/\*\//d; 1r newSig.txt' input.txt

第一个 sed 的问题命令从以下位置删除签名第2行直到签名结束.您可以使用动态范围，但也会删除文件中的其他多行签名.第二条命令读取具有新签名的文件 newSig.txt ，并将其附加在第1行之后.

The first sed command deletes the signature from line 2 til the end of the signature. You could use a dynamic range but it would also delete other multi-line signatures in the file. The second command reads the file newSig.txt, which has your new signature, and appends it after line 1.
