Hi Epictete,

I was using the _ character as part of the selection pattern, because that was in your example. If your actual files do not contain a _ character before the number then it does not work.

You can also use another criterion, e.g. the part of the filename before the number contains no numbers:

e.g:

Code:
ls | while read name
do
  ext=${name##*.}
  first=${name%.*}
  pre=${first%%[0-9]*}
  nr=${first##*[^0-9]}
  newnr=$(printf "%03d" $((nr-214)))
  mv "$name" "${pre}${newnr}.${ext}"
done
