Searching WinXP using win-bash and Gnu grep

Hi,

I'm trying to do a recusive search of all files containing either "ipso" or "lorem", starting in directory

K:/_Projects/JavaScript

.

I'm running GnuWin32 grep in win-bash within a WinXP/SP2 Command Window.

Here's the code from three tries

bash$ pwd
K:/_Projects/JavaScript
bash$ grep -l -i lorem *.*
grep: *.*: Invalid argument
bash$ grep -r 'ipso|lorem' .
grep: ./.metadata/.lock: Permission denied
bash$ grep -r 'ipso|lorem' K:/_Projects/JavaScript
grep: K:/_Projects/JavaScript/.metadata/.lock: Permission denied

Any ideas on how to get this working?

TIA,
Richard
