如何将文本块添加到所有子目录中的所有 PHP 文件？

Question

我有一个 PHP 脚本，我需要在顶部添加我的版权。我只是希望它出现在之后

以下是需要添加的内容：

/**

 * This file is part of MySoftware.
 *
 * MySoftware is free software: you can redistribute it and/or modify

*/

如果可以在上述消息之前和之后添加一个空行，如果可能的话，它会在每个文件中更加突出。

将它添加到我所有的 php 文件顶部的最快方法是什么？有数百个，我已将它们全部移动到一个主文件夹/子文件夹中，因此我认为可以使用命令行递归运行某些内容以将其添加到每个文件夹的顶部。

如果有人可以通过命令行或任何其他方法发布如何执行此操作的示例脚本/代码，将不胜感激！

Answer 1

将您的文本保存到文件中，例如/tmp/header，然后运行以下脚本。

DIR=/your/php/files/dir
for f in $(find ${DIR} -iname "*.php" -type f 2>/dev/null) ; do
    cat /tmp/header "${f}" > /tmp/tmp_file || continue
    /bin/mv /tmp/tmp_file "${f}"
done

Answer 2

#!/bin/bash
text="Hello world
What's up?"

exec 3<> $1 && awk -v TEXT="$text" 'BEGIN {print TEXT}{print}' $1 >&3

试试看。
