[GRASS-user] Running Scripts in GRASS

[Andrew Lewin]

Thanks for the help, but I am not quite clear on the part you say the  
script has to be an executable.  I copied and pasted the script from  
the wiki page and stored it in ~/Library/GRASS/6.4/Modules/bin; called  
the script by typing it (called chlatransl) to the Terminal shell.  It  
said "chlatranl not found".  How do I compile the script to make it an  
executable.  Right now it is stored in a text file.

I apologize for being naive.

Andrew
