[GRASSLIST:5550] Fwd: Re: Command-line invocation

[Michael Ash]

Thank you very much for the information.  

I had originally asked if it was possible to start GRASS from the command line with a script because I have to process multiple mapsets.  I would prefer to avoid manually starting and restarting GRASS between runs of a GRASS script because the number of mapsets is fairly large (the countries of Africa).

As it turns out, it is possible to change mapsets within a GRASS session.  See the other reply to my message for details, but the GRASS bash shell script I will run is:

for j in <list of countries> do;
  g.gisenv set=MAPSET=$j;
  for i in <list of vectors> do;
    v.support $i;
  done;
done;

I will probably generate the <list of countries> and <list of vectors> with file listings, wildcards, and extraction.  (See the bash documentation for details.)

Thank you to GRASSLIST for the information on g.gisenv and the very helpful basis for the script.
