Need help is manipulating a file with some arithmetic operations using bash script
Friends,
I have a file with contents like:

interface Serial0/4/0/0/1/1/1/1:0
encapsulation mfr
multilink
group 101

Now I need to manipulate the file in such a way that to all the numbers less than 163, 63 gets added and to all numbers greater than 163, 63 gets deducted.(The numbers means the numericals after "group") How do I do this using a bash/shell script?

Thanks
Shrijit
