[GRASS-user] v.out.ascii -- surpressing vector IDs?

not sure if I understand your question,

$ v.out.ascii x
1619923.0297213|4836235.79480289|0.01571819|1
1619927.57223432|4836235.09835698|8.05628783|2
1619910.45256599|4836241.22590928|6.82026114|3

To eliminate category number from output (4th column), you can use e.g. awk

$ v.out.ascii x | awk -F'|' '{OFS="|"; print $1,$2,$3}'
1619923.0297213|4836235.79480289|0.01571819
1619927.57223432|4836235.09835698|8.05628783
1619910.45256599|4836241.22590928|6.82026114
