print output

The \033[0m on line 96 displays nothing when running from the command line (just the newline), but when running from within GeekTool I see a black "[0m" on a new line:

Deleting \033[0m gets rid of it in GeekTool - the newline is still output when running from the command line. I'm no expert on ANSI escape sequences - what does that one do?

Thanks
