IMHO it would be helpful to add a flag to v.edit to also delete the
database entries when tool=delete.<br>
In general use, when I delete a feature, I don't expect to leave
orphaned entries in the attribute table.<br>

<div>
<p class="MsoNormal">what would be
the most GRASS-like way to
delete several points from a
points vector map. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I know the
specific cats of the points I
would like to delete (10 of
200000) and I want to delete the
points from the map and, of
course, also from the
corresponding attribute table. I
already tried v.edit but here
the points are not deleted from
the attribute table. I could
also use v.extract with the
reverse flag, however this
requires to define a new output
map (which I would like to avoid
if possible). Any straight
forward way in GRASS?</p>
