Sheryl,

This isn't a "dot problem".  This is a grep usage problem.

Frankly, I don't see why you are so opposed to 'find'...  'find . -name
\*.vb\* -exec grep -ni path32 {} \; -print' can be a very powerful tool.
If you want the filenames printed before the matches (ala 'grep -R'),
consider using 'find . -name \*.vb\* -print | xargs grep -i path32'.  If
you have files with spaces and weird characters, try 'find . -name \*.vb\*
-print0 | xargs -0 grep -i path32'.

Of course, if you really want to stick with "pure grep", you could always
do 'grep -i -R path32 --include=\*.vb\*' (now that I've pitched in an
argument in favor of "find" :-D)...  'info grep' should also be quite
helpful.
