Indeed it does. I was aiming to show that for simple tasks like this,
a modern shell makes things easy enough that scripts become overkill.

You can just add in a printf to go, e.g., from a padded 001 to 360:
c=1 && for f in * ; do echo mv $f CD267A_3_pk_1_`printf "%03d" "$c"`.img ;
c=$(($c+1)) ; done
Or a more specific set of images:
c=1 && for f in CD267A_3_pk_1_*.img ; do echo mv $f CD267A_3_pk_1_`printf
"%03d" "$c"`.img ; c=$(($c+1)) ; done
Or an even more specific set of images:
c=1 && for f in CD267A_3_pk_1_{1081..1440}.img ; do echo mv $f
CD267A_3_pk_1_`printf "%03d" "$c"`.img ; c=$(($c+1)) ; done
I guess once it gets complex enough then you might as well go down James'
path and create a generalized script that can be used in many cases, but
it's definitely more work to write the generalized script than to toss off
one liners.
