humm.. sounds stupidly simple but whats the command for listing the CVs.. or getting the number of CVs?!?!

But theres an undocumented mel-command selectCurveCV that does the job. You can see it If you do the Ctrl-RMB-thingy on a curve.

A look into the selectCurveCV.mel should clarify I guess 😜

Aaahhh its not a command it an attribute:

getAttr -size ($curve + ".controlPoints")

string $cvs[] = `ls -sl -fl`;  
select -cl;  
string $c;  
for( $c in $cvs ){  
 &nbsp; select -r $c;

}

don't bother messing about with select though, just do:

ls -fl "curve1.cv[\*]";
