[Scott Cason]

i am running grep:

grep (GNU grep) 2.5.1

on a windows xp/sp2 platform.

i am trying to run the following:

grep -r --include='*.c*' 'dat' c:\tc\cdev



and i get nothing returned.  basically, i want to initiate a recursive
directory search targeting only check the *.c and *.cpp files for the
specified string.  is there NOT a straight-forward way to do this with this
tool?

if i run "grep -r 'dat' c:\tc\cdev"  i get output along with output from
files i do not want.  i have also tried other variations of the flags.


thanks,  scott
