Open a folder in the Finder from the Terminal
November 1st, 2003 by Marcos
Here’s a simple but nifty trick. Say you’re navigating around in the Terminal and you would like to see the present working directory in the Finder? Just type
% open .
and the Finder will open up the folder you’re in. This works in both xterms and the Apple Terminal.

Nice one. Having searched for a while, only finding “how to open a terminal window from the finder”. I’d expect it to be “finder .”, but I guess I can not always have my way.
