Nope, the 'grep -v' means that entire row of data is excluded from the datastream and never sent to v.in.ascii in the first place. I just used NULL=99999.99 as an example, NULL= could be set to anything. If you need the x,y row there, but with empty values instead of 9999s in some column, then db.execute might be a faster way than v.db.update to clear them (only open and close the DB once), but v.extract with where="value < 9998" might be fastest of all.
