Substract a certain number to the names of several files
We have a list of files (raw and jpeg types) with 2 different extensions (rw2 and jpg).
When there is both the raw and jpeg files, their file numbers must be the same (215 and 215, 218 and 218).
Sometimes there is only the jpeg file (216,217).
bla_215.rw2
bla_215.jpg
bla_216.jpg
bla_217.jpg
bla_218.rw2
bla_218.jpg etc
Is it possible to have a new numerotation starting from 001 AND respecting the rules above?
Maybe substract 214 so that 215 becomes 001, 216 becomes 002, etc
BUT 215.cr2 and 215.jpg must stay linked together by their new numbers: 001.cr2 and 001.jpg?
Thank's.

PUZZLE-DIFF(1) PUZZLE-DIFF(1)
NAME
puzzle-diff - Compare pictures with libpuzzle
SYNOPSIS
[-b <contrast barrier for cropping>] [-c] [-C <max cropping ratio>] [-e] [-E <similarity threshold>] [-h] [-H <max height>] [-l <lambdas>]
[-n <noise cutoff>] [-p <p ratio>] [-t] [-W <max width>] <file 1> <file 2>
DESCRIPTION
puzzle-diff compares two pictures and outputs the normalized distance.
Try puzzle-diff -h for more info.
EXAMPLES
Output distance between two images:
$ puzzle-diff pic-a-0.jpg pics-a-1.jpg
0.102286
Compare two images, exit with 10 if they look the same, exit with 20 if they don't (may be useful for scripts):
$ puzzle-diff -e pic-a-0.jpg pics-a-1.jpg
$ echo $?
10
Compute distance, without cropping and with computing the average intensity of the whole blocks:
$ puzzle-diff -p 1.0 -c pic-a-0.jpg pic-a-1.jpg
