Selection of Lines by number of verticies

Hi All,

I have an interesting problem, we have a pipeline layer which is made up of thousands of individual lines, most of which are straight (2 Vertices - beginning and end).

the data was created many moons ago and when it was generated some of the lines ended up with extra vertices, unsure why..

What I would like to do is to perform a selection on the lines identifying any of these lines that have more than 2 vertices.

The reason for looking for these is that some of the pipes that are represented by these lines with the extra vertices have bends in them when they are supposed to be straight.

Any help would be appreciated.

Cheers

Scott
