No, those parameters don't exist for db.select. db.select uses table= instead of map=. There also isn't a column parameter, so you'd have to use some SQL commands to get the column you need. Note you can omit the column heading name in the output in both db.select and v.db.select by using the -c flag: db.select -c table=Matthew_2005013_Navigation | head -10 1|1860029|636162.13|5156960.89 2|186002910|636194.64|5157012.42 3|186002920|636229.43|5157064.57 4|186002930|636263.7|5157116.26 5|186002940|636297.62|5157169.61 ... ~ Eric. db.select table=TABLE > > ~ Eric.
