How to "mass" renaming files

[MCR]

Here is a script that I have been using a lot lately,
it is a simple shell scripts:

#!/bin/bash
number=12
for img in  *.jpg
do
        mv $img $number.jpg
        $((number = number + 1))
done

this will take all file in a directory that ends in
jpg and will rename it to the name of $name.  You can
set $name to start at what number you want and it will
increment by one.  I have gone as high as 253
pictures, I do not know what number it will stop at.

Hope it Helps.

One is led to truth through the interpretation of a myth.
