Hi:<br>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.<br>So today I change to Ubuntu, and I install grass use sudo apt-get install grass.<br>
<br>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.<br>First I run grass in text model in the ternimal by " grass -text",<br>
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):<br>
