On Unix, yes.  But DJGPP has a hidden treasure in its filename-globbing 
code: the special wilcard "..." recursively expands to all of the 
subdirectories.  So, e.g., "grep go32 c:/djgpp/include/.../*.h" will find 
all the instances of "go32" in all the DJGPP header files.

On Unix, the usual way is to say something like "find . -exec grep ...".

If you need to search files written is some programming language, a
better tool is `lid' from GNU ID-utils (v2gnu/idu32b.zip).
