[colug-432] Bash script two digit names

[Tom Hanlon]

Colug,

I have a bash script that loops and create files.

THink dates..

I go through and create a file

01_1 for jan first
01_2 for Jan second.


Problem is I would much rather have

01_01 rather than 01_1

The loop goes from 1-31 and sets the variable for the loop counter.

Is there a built in utility to make a "one space" integer a "two  
space" integer, or do I have to do that manually ?

Just curious, I am not stumped, but not looking to reinvent the wheel,  
and would like to use a built in if one is available.
