Start by testing whether g2ctl works on your grib2 file; use the g2ctl.exe
version.

I am a bit confused. Which shell are you using? Are you using the Perl
version (g2gdf.pl) or the executable "g2gdf.exe"? If using the script
version you must use a Cygwin compiled perl, or else you may need to use
"dos2unix" to convert the resulting text files .gdf/.inv. Also, use POSIX
file names with forward slashes: c:/grib/input_new/multi_1.wc_4m.t12z.grib2
My recommendation would be for you to start with g2gdf.exe and g2ctl.exe
which should already be in your win32 directory. Next, try these with POSIX
file names. And if using g2ctl.pl with perl/cygwin, you need the win32
patched version.

  Let me know how it goes. Are your particular grib-2 files available
on-line?
