Git: copy all files in a directory from another branch

Question

How do I copy all files in a directory from another branch? I can list all of the files in that directory by doing

git ls-tree master:dirname

I can then copy all of the files individually by doing

git checkout master -- dirname/filename

However, using wildcards has so far been a total fail. git checkout master -- dirname/*.png does nothing. Though I guess I can use a bash script to do that, there has to be an easier way, right?

As you are not trying to move the files around in the tree, you should be able to just checkout the directory:

git checkout master -- dirname
