I'm writing a bash script to get some podcasts. The problem is that some of the podcast numbers are one digits while others are two/three digits, therefore I need to pad them to make them all 3 digits.

I tried the following:

n=1

n = printf %03d $n

wget http://aolradio.podcast.aol.com/sn/SN-$n.mp3

but the variable 'n' doesn't stay padded permanently. How can I make it permanent?
