Git: copy all files in a directory from another branch
提问by alexenko
How do I copy all files in a directory from another branch? I can list all of the files in that directory by doing
如何从另一个分支复制目录中的所有文件？我可以通过执行列出该目录中的所有文件
git ls-tree master:dirname
I can then copy all of the files individually by doing
然后我可以通过执行单独复制所有文件
git checkout master -- dirname/filename
However, using wildcards has so far been a total fail. This does nothing:
但是，到目前为止，使用通配符完全失败。这没有任何作用：
git checkout master -- dirname/*.png
Though I guess I can use a bash script to do that, there has to be an easier way, right?
虽然我想我可以使用 bash 脚本来做到这一点，但必须有一种更简单的方法，对吧？

As you are not trying to move the files around in the tree, you should be able to just checkout the directory:
由于您不想在树中移动文件，因此您应该能够检出目录：
git checkout master -- dirname

If there are no spaces in paths, and you are interested, like I was, in files of specific extension only, you can use
如果路径中没有空格，并且您像我一样感兴趣，仅在特定扩展名的文件中，您可以使用
git checkout otherBranch -- $(git ls-tree --name-only -r otherBranch | egrep '*.java')
