[GRASSLIST:9289] number of rows in a table?

[Kirk Wythers]

I need to find the number of rows in a table. I have some vector  
files that crash qgis, yet grass opens them fine. Looking at the dbf  
files, I suspect the the issue is the file size (20 - 30 MB). I  
wanted to check the number of rows and I've been looking through the  
db commands, unfortunately, so far all I have come across is using  
using db.describe to get the number of columns. Any suggestions?

Thanks,

Kirk
