[A.N.NDUMU]

Hello,

I am new to GIS and I am trying to install Kang's binaries (v4.1.3) 
on my GNU Linux workstation. Installation is OK, but when I type 
grass4.1 at the command line, nothing happens. On further 
investigation, I discovered that the program exits when running the 
GIS.sh file. Here is the segment of the file where I think the 
problem is:

#user selects LOCATION and MAPSET

$ETC/gis_set
case $? in
0) ;;
*)exit
esac

I have no idea of shell programming, but from my rudimentary C 
programming knowledge, some parameter is not set up properly when 
$ETC/gis_set is executed, prompting the exit option in the following line 
of code.

Can anybody tell my why this is the case  or what I am doing wrong.
Thanks for your help.
