Like you said I try the following:

$v.in.ascii -z input=/home/tiago/teste output=teste_out format=point
fs=tab skip=1 columns='x double precision, y double precision, z double
precision, cat int' \ x=1 y=2 z=3 cat=0

with teste file like this:

x	y	z
1	1	1
2	2	2
3	3	3
4	4	2
5	5	1

GRASS just didn't made anything. Do you have some idea about what is wrong?
Thanks again!
