Hi: I have post this problem before, I want to run grass in command line model so I can call them in java at that time,however it often cause some unexpeced errors. So today I change to Ubuntu, and I install grass use sudo apt-get install grass.
Now I also want to call grass in my java code but in the Ubuntu platform, I want to know which environment variables are needed, so I did some tests. First I run grass in text model in the ternimal by " grass -text", and I chose the location and mapset,it works, then I use command "set > /home/kk/var" to get all the environment variablse using by grass ,then I open a new ternimal to get the normal env vars by " set > /home/kk/varn" . Then I compare the two files and tried to find the differences. I found that there are more variables in the varn rather than var (shown below): ----------- GISBASE=/usr/lib/grass64 GISRC=/tmp/grass6-kk-9581/gisrc GIS_LOCK=9581 GRASS_GNUPLOT='gnuplot -persist' GRASS_HTML_BROWSER=x-www-browser GRASS_LD_LIBRARY_PATH=/usr/lib/grass64/lib GRASS_PAGER=pager GRASS_PERL=/usr/bin/perl GRASS_PROJSHARE=/usr/share/proj GRASS_PYTHON=python GRASS_SH=/bin/sh GRASS_TCLSH=tclsh GRASS_VERSION=6.4.0RC5 GRASS_WISH=wish ----------- So I want to know if these vars are enough?
