[GRASS-user] creating a new mapset in an existing location

Dear List,

Is there a way to create a new mapset from the command line?

My use case is that I'd like to run parallel jobs (with GNU parallel).

But,

...it's recommended to launch each job in its own mapset within the
location.

according to ttps://grasswiki.osgeo.org/wiki/Parallel_GRASS_jobs

I'd like to have the parallel calls create the new mapset, each named JOB_SLOT_NUM (up to n CPU cores). I don't know in advance if I'll be spawning 4, 8, 16, etc. parallel jobs.

Thanks,

  -k.

grass -c /PATH/TO/LOCATION/newMapsetName

does the trick.

If you only want to create the mapset, but not enter it, you can use:

grass -ce /PATH/TO/LOCATION/newMapsetName

Right. Sorry for the silly question. I thought that "-c" was only for
creating locations, but it clearly says it creates mapsets too. Thank
you!
