grep resistance

[Tony Laszlo <laszlo@example.com>]

It is apparently not possible to grep 
through a directory which has a large 
number of files (perhaps the limit 
is someone near 1,000 or so). 
I happen to have a directory which has 
more than 10,000 files and found 
that grep gives the error 
"Argument list too long." 
Here is a workaround which works 
pretty well: 

find . -type f -exec grep -n -C STRING '{}' ';' | less 

problem is, it doesn't display the name of the 
file. Can this be adjusted to do so? 

Thanks!
