ls -R works identically as grep -R ...

the ls command merely 'defaults' to . if no file is given - where as grep 
defaults to 'stdin' .

try ls -R *.vb* - you will see it gives you nothing as well.

-R means 'recurse any directories in the input set.'
when the input set is *.vb* - theres no directories - so no recursion 
occurs.

Gareth - idly ponders why the grep he installed himself on this dec machine 
doesnt have --include.
