[GRASS-user] Stopping/killing a "puased" command

[Blumentrath, Stefan]

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)?

Cheers
Stefan

Hi Stefan,

can you pipe the MarZone output into a tmp file, check that file in
regular intervals for the desired string and stop the process if the
string is found. Not the most beautiful way I can think of but maybe
an option ..

Cheers,

Stefan
