Re: [GRASS-user] Stopping/killing a puased command
Hi Stefan, Many thanks, that sounds like a good idea. MarZone produces output files by default, and I could regularly check if the last output file has been produced. But how can I do it in parallell to executing MarZone (I mean in the same script?), could you point me to the relevant command(s)?
