[GRASSLIST:8375] Re: Remote execution of grass53 commands

[Suprit Kumar]

Thanks Glynn and Tom!

I appreciate your timely help and suggestions and hope will be able to write 
better scripts following them .
Also  I was able to run commands(script) in Grass5.3 non-interactively on a 
remote machine using the following as suggested by Glynn.
ssh <remote-machine> sh -c '"SHELL=/path/to/script 
grass53  /home/suprit/grass53/GISDBASE/LOCATION/MAPSET"'

 
With regards,
Suprit
