[GRASS-user] shell script problem

[Mario Giacomello]

Dear all,

Apologies for the total beginner's question, but despite my efforts
and searches through the GRASS mailing list archives I have not been
able to solve my problem. I am trying to write a simple grass script
in order to automated a process, but I have not very far yet. One
thing that I would like to do is to be able to change the region, but
GRASS seems to come up with the whenever I , for example, try to use
the following simple lines:

#!/bin/sh

g.region rast=map1
r.stats -ln map1 > file1

The message I get is: "command not found". What am I doing wrong? Is
this problem related to the setting of environment variables?

I am using GRASS 6.3.0  installed on Ubuntu 8.10

thanks in advance,

Mario Giacomello
