[GRASSLIST:600] Re: How to Run GRASS modules at bash prompt

[Nagesh Bhatkar]

Hello Benjamin,

Thanks for writing back and dropping in your Suggestion.
I have installed the Entire GRASS 6.0.1 package on my system since i 
have being using GRASS extensively since
a long time to interpolate data  and  carry out digitization . I agree 
with you that  GRASS 6.1 is a tiny total of 72 MB in modern day era.
I wanted  to use the GRASS commands at the bash prompt. Was looking if 
anyone could give me suggestions as to how i could make that possible.
Am aware thats its an ardous task but might as well give it a try. 
Earlier i read in the GRASSLIST archives, one of the GRASS users asking 
for the same.




Regards

Nagesh
