[GRASS-user] Detect failure during batch job execution

[Andre Hauptfleisch]

Hey guys,

I've been using the batch processing feature in grass and it works amazingly
well.

Unfortunately the v.generalize's hermite method dies on me every once and a
while.

Is there a way to detect whether an operation has succeeded or failed? Or
whether a vector layer exists or not?

Regards,
Andre


Here is the error msg:
