On a similar note, if you just want to open a new Finder window to the current working directory (instead of using an existing Finder window), just use open . The 'open' command has tons of uses (open a file with a specific application, reveal a file in Finder, open a URL in the user's browser, etc.) and I recommend reading its man page.
