Chris, this works, (well I haven`t tried actually running the resulting
output) but, It only outputs a command line once the limit has been reached.

Meaning that if the source files are less that Limit it does not output
anything, If over the last few folders are not output.

My guess is that I need to add an extra print line, which executes once stin
is closed at the end of the directory listing. How do I do that?

Thanks
