Command Line Access in OS X

HI guys. Great program (Like you didn't already know that)

My issue is this: I running a scrape that downloads a lot of information for each page. After 30-40 of these pages the program hangs. My impression, from other entries in the forum, is that the overhead of the workbench contributes to this problem and that the solution is to run it from the command line. Unfortunately, because (1) I'm a newbie and (2) I'm using a Mac, this process is less than intuitively obvious. The only instance of the screen-saver.jar that appears to exist is in the Applications folder. Is this correct? Any other hints on how to run it from the Terminal.

Thanks.
