[GRASS-user] v.split: Strange behaviour

[Jachym Cepicky]

hi,

what about v.edit ?

# new file with vertexes
v.to.points in=roads out=tmp -v 

# copy original file
g.copy vect=roads,myroads

# run v.edit
for line in `v.out.ascii tmp`; do 
     eval `echo $line|sed -e "s/^/x=/" -e "s/|/; y=/" -e "s/|.*//"`;  
     echo $line; 
     v.edit -t map=myroads tool=break coords=$x,$y >/dev/null 2>&1; 
done

well, it is not the best solution, but seems to work, but it failed for
me after 39 vertexes :-/
