This is admittedly a pretty naive fix, but should get someone who's more familiar with the code base going in the right direction anyway.

hey many thanks for this. I've made some changes to comply with *nix behavior (only create dest dir if it's one level deep), and simplified the logic and tests a bit in cba4f22 (sorry, my editor also removed a bunch of trailing spaces making the diff hard to read)

PS: but your two commits are in the tree of course! :)

Very cool, thanks! :)

Sorry to bring this up again, but when I run npm test locally with the current head of master, I get the following:

shell.js: internal error

*** TEST FAILED! (missing exit code "123")

If I comment out the last test block in test/cp.js it passes fine. Not sure what causes it, and am sort of pressed for time at the moment (focusing on trying to implement pushd/popd as per #24 at the moment,) but if I figure it out I'll make sure to get back to you. Just figured I'd drop a note about it.

Here's some machine info, in case it's useful:

Also, node version:

$ node -v

Silly me had screwed up the merge of your master into my fork, it's all good. My bad, please ignore!

pheew! :)
