of course, there should be a space. Copied directly from a *working*
GIS.sh:

The same kind of if/fi wrapper should probably be put
around the pesky "GRASS SESSION WRAPUP."

I suppose that it might also be nice to to have a "-e"
flag (or "e=xxx") to execute only one command and
then exit grass immediately, but I'm not sure if
I could make this work with all shells.
