[GRASSLIST:4179] redirecting v.what results to file using batch-grass

[Andrew]

Hi all

I've managed to get the v.what command to redirect it's results to file
(using >) but I'm having some problems doing this when using
batch-grass.sh.  I always get the same error message:

Sorry <>> is not a valid option
Sorry <v.whatoutput> is not a valid option

and I get the same if using | instead of > (1st error message obviously
changes the invalid sign)

My full batch-grass line is (in Pascal)

Exec('batch-grass.sh stellenbosch andrew v.what map=stbstreets_wgs84
east_north=18.830,-33.935 > v.whatoutput','');

Any ideas?
Thanks
Andrew
