I was working on a site for a friend who's a photographer and provided me with a set of JPG files that were names like

-rw-r--r--@ 1 devraj  staff  4367696 28 Sep 14:54 _DSC0156.JPG
-rw-r--r--@ 1 devraj  staff  4261008 28 Sep 14:54 _DSC0163.JPG
-rw-r--r--@ 1 devraj  staff  3881646 28 Sep 14:54 _DSC0170.JPG
-rw-r--r--@ 1 devraj  staff  5858034 28 Sep 14:54 _DSC0178.JPG

I wanted to rename them into a sequence like 001.jpg, 002,jpg

This script provides the basis of the counter renaming the files with `padding applied to the numbers, resulting in:

_DSC0110.JPG -> 229.jpg
_DSC0114.JPG -> 230.jpg
_DSC0117.JPG -> 231.jpg
_DSC0120.JPG -> 232.jpg
_DSC0153.JPG -> 233.jpg
_DSC0154.JPG -> 234.jpg
_DSC0156.JPG -> 235.jpg
_DSC0163.JPG -> 236.jpg
_DSC0170.JPG -> 237.jpg
_DSC0178.JPG -> 238.jpg
