<BODY>
<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>Repeatedly there have been requests to make it possible to quit GRASS when quitting the GIS Manager (and to automatically quit the GIS Manager when quitting GRASS). <BR>
<BR>
I had an idea that I thought I run by everyone and see if I could get some suggestions about getting it to work.<BR>
<BR>
1. When the GIS Manager shell script is first run (gis.m& to run in background), have it set an environmental variable. For example...<BR>
export GRASS_GUI_RUN=”TRUE”<BR>
<BR>
2. The script would idle away, waiting for any change to the environmental variable (this is a part I’m not sure how to do)...<BR>
while GRASS_GUI_RUN==”TRUE”<BR>
... let the GIS Manager run<BR>
<BR>
3. When the GIS Manager quits (or quits with an option to exit GRASS), it could set this variable to false<BR>
set env(GRASS_GUI_RUN) “FALSE”<BR>
<BR>
4. The script would exit its while loop and echo “exit” to the GRASS command prompt, “shutting down” GRASS (i.e., resetting the GRASS environment and closing the GRASS shell).<BR>
<BR>
Would something like this work???<BR>
<BR>
If so, we also might be able to use this for automatically quitting the GIS Manager. <BR>
-Write into the GRASS exit routine a check for the GRASS_GUI_RUN environmental variable<BR>
-If it is set to TRUE, kill WISH.<BR>
<BR>
What do you think?<BR>
