gimp help

any body familiar with using gimp in batch mode?
if so, please help.
i want to utilize the Script-Fu. instead of user interaction, i want to run it in batch mode.

gimp -n -b (command goes here)

does anybody know how to get the command for some of the options in Script-Fu? say i want to apply the FUZZY BORDER in Decor menu of Script-Fu. what is the command for Fuzzy Border in batch mode?
thanks
