我想最简单的方法是使用SED做了查找和替换在此版权头的所有地方。 我有点Unix的新手，所以我在得到命令工作的问题，我需要它的方式 - 尤其是对付多行字符串。 基本上，像下面，除了代替的相应报头foo和bar ：
find . -name "*.java" -print | xargs sed -i 's/foo/bar/g'
我明白了一个行sed的作品在同一时间，也许有更好的解决方案完全？
find . -name "*.java" -print0 | xargs -0 \
sed -i -e '/Project Foo is free software/,/along with Project Foo/c\

的c命令改变行指定的文本的范围内。 范围由含有“FOO项目是免费软件”到包含“与FOO项目沿”行了行标识。 该-i选项sed表示GNU sed ; 因此，我假设你已经GNU find和xargs过了，使用-print0和-0避免与文件名等空白问题
对于这一点，我可能会尝试把sed脚本到一个文件中（ sed.script ），其然后可以与使用：
find . -name "*.java" -exec sed -i -f sed.script {} +
这是整洁的，但是我认为，美在旁观者的眼睛。
只有一个问题：对齐是一个小关的星号，是有某种形式的空白字符我需要使用缩进他们？ 我尝试添加空格替换字符串，但似乎没有任何效果。
哎呀......这就是那种刺激我可以没有（和你太）。 看来，在“变”的数据线前导空格都下降了sed 。 这似乎是sed ，而不是bash ; 我得到了同样的结果ksh ，也可以通过脚本文件，而不是-e命令行选项。 因为它是输出不能编辑的“变化”的数据。
一招，将工作 - 但你可能并不热衷于它：
$ cat sed.script
/Project Foo is free software/,/along with Project Foo/c\

$ s2p -f sed.script > perl.script
$ find . -name "*.java" -exec perl -f perl.script -i.bak {} +
$
该s2p程序是转换的Perl分布的一个标准部分sed脚本转换为Perl脚本，但它保留在替代数据的前导空格。 我并不热衷于这一点，但我能想到的唯一的办法是通过每个文件进行两遍。 替换数据可能是：
$ cat sed.script
/Project Foo is free software/,/along with Project Foo/c\

$
这样做的主要文本替换后，你会然后做：
$ find . -name "*.java" -exec sed -i 's/^@\*@/ */' {} +
$
这追寻的线条开始@*@和替换文本“ * ”（空白星级）。 还不如整洁，但你不会被经常做这一切，我相信。
部分许可证更换使用GNU桑达
您可以使用GNU sed的一些正则表达式匹配的线和读表达解决这个问题。 下面是步骤。
使用文件来保存替换文本
首先，创建一个文件来保存您的许可证的更换部分：
cat << EOF > /tmp/license
*

* you may not use this file except in compliance with the License.

EOF
运行实际桑达调用
接下来，运行发现收集您的文件列表，并调用下面的sed脚本来进行更改：
find . -name '*.java' |
xargs sed -i'' '/Copyright.*Tyler Treat/,/\*\// {
/Copyright/n
/\*\//r /tmp/license
d
}'
兼容性注意
该解决方案可能会或可能不会与sed的其他版本，但在本地测试，并与著名的GNU sed的4.2.1版本的工作。 如果它不与sed的随附OS X版的版本中运行，可以安装GNU sed中通过的MacPorts或相似。
假设文件1包含您的原文和file2包含您的版权置换的评论：
awk 'f; /\*\//{system("cat file2");f=1}' file1
以上只是查找第一个结束注释行的原始文件，当它找到猫的替换文件和为原文件的剩余部分进行打印圈。
