[GRASS-user] problem with v.edit tool=merge

[Martin Landa]

Hi,

you can use v.out.ascii, e.g.

v.out.ascii lines for=standard | grep -v ':'
L  2 1
 593032.40082212 4921689.97052779
 595110.2466359 4921611.5612518

 599357.41575212 4921206.44665917
 1     3

g.copy vect=lines,lines1

v.edit lines1 tool=merge cats=1,2
[2] of [3] features selected
Editing: [2] lines merged
