[GRASS-dev] v.edit doesn't work as described

[Huidae Cho]

Michael,

Attempt #1.

You need new lines between type, coordinates, and category lines.
echo "P 1 1
583290 4785860
1 1" | v.edit -n tool=add map=sites2 input=-

should work. The manual looks correct. I tried to put all three lines in a
single line and got the same error.

Attempt #2.

You need to export to the standard format. v.out.ascii map format=standard.
The manual also mentions format=standard.

Hope this helps.
