OK, you either want to use v.patch or v.overlay, and you want to do it 
via a script so you don't have to handle things manually. Well, ok, six 
files isn't too many ...

Although it can show some bad habits, v.patch is probably the better 
tool here ... eg (in Australia not the US):

v.patch input=NSW,QLD,VIC,SA,WA,TAS,NT,ACT output=Australia -e

This will fail, however, if the tables aren't identical.
