[GRASS-user] automatically add verticies to lines

is there a command to add vertexes to a line (even if not necessary to define a straight line) ? meaning if i have a line defined as nodes 0,0 and 0,50, i would like the nodes and vertexes to be: 0,0 0,10 0,20 0,30 0,40 0,50

Basically i would like to add verticies at a specified interval, to all lines.

v.segment seems like it might work, but i dont understand how to input that into it.

In addition to v.segment, try:
  v.split, v.to.points, v.lrs.*

its too bad v.clean doesnt snap to a line when no vertex present.
but this will work good i think to split the line up with verticies so
that v.clean can work its magic.

if lines cross then tool=break,rmdangle will work. If lines only come
close, I guess you could do "v.split vertices=1; v.clean tool=snap thresh=;
v.build.polylines".

I am surprised "v.distance output=connecting_lines" +
"v.clean tool=break,snap" didn't work -- distance-lines [should] end
directly on the polyline so in theory ok for v.clean...?
