[GRASS-user] Merge polygone with same attribut of a shapefile

Dear all,

I'm trying to merge all polygones with the same attribut of a shapefile. I saw it is possible to merge adjacent polygone with r.dissolve but I didn't found how to do this with polygones that are not adjacent. Is there a way to do this?

My goal is to minimise the number of feature into my table in order to have only one feature by category, but containing several polygones.
