Thanks Hamish and Markus for the reference. Is there a way to have the file
loader dialog box open in a certain directory like $GISDBASE, for instance?

add to the option definition:

#% gisprompt: old_file,file,input

e.g. m.proj.

While we're on the topic, can anyone explain why there are usually
several gisprompt parameters allowed for in most Grass shell scripts?
What do all these mean?
   
somewhere deep in the programmers' manual or lib/gis/parser.c ...

from memory:

old/new - whether to open map/file browser; checks that it won't

overwrite

element - the directory in $MAPSET, if applicable
prompt - mostly unused nowadays?

Here is the list:

It is just the pwd, cd to there in the script first. I don't know
how the parser will treat that though- it might cause problems.

#!/bin/sh
eval `g.gisenv | grep GISDBASE`
cd "$GISDBASE"

#% option
