Try out like this: for x in `seq 1 5`; do v.extract --o in=bclust where="cluster="${x}"" out=bclust_"${x}" v.hull --o in=bclust_"${x}" out=bclust_hull_"${x}" d.vect bclust_hull_"${x}" type=boundary fcol=none width=2 col=white d.vect bclust icon=basic/box fcol=black col=black size=6 done By the way, I remember reading expert comment in the list that using "${x}" is rather a good idea.
