Hi Andrew,

This works:

#!/bin/bash
typeset PATH_TO_FILE_DIR=/tmp/somedir
typeset oldPattern='6H9A([0-9]+)\.CR2'
typeset newPattern='6J9A\1\.CR2'
for f in ${PATH_TO_FILE_DIR}/*; do
    typeset oldName=$f
    typeset newName=`echo "$f"|sed -r "s#$oldPattern#$newPattern#g"`
    if [ "$oldName" != "$newName" ]; then
        echo mv $oldName $newName
        mv $oldName $newName
    fi
done

You just need to change /tmp/somedir to the directory where the files are, then save the text above as a script, say renamefiles
and then do a:
chmod u+x renamefiles
then run it via:
./renamefiles

It will print out all the files it finds and changes.

Hope that helps

Subject: Renaming files
 
Hi all,
My camera has just ticked over 10,000 images in around 8 months, and so
another folder has opened up on the SD card, prior to today the file
folder was 100EOS5D, the new folder is 101EOS5D, but the counter has
reset from 6H9A9999 to 6H9A0001. At this rate I cannot afford to have
the same file numbers repeating in the same calendar year. I can go into
the Camera and change the file numbering to 6J9Axxxx, but how can I run
a bulk renaming of my Raw Files - not being a scripter I am at a (self
imposed) disadvantage,

I have tried to understand the several ways to achieve this,but I have
not grasped it.

Rename 6H9A0001.CR2 6J9A0001.CR2
Rename 6H9A0002.CR2 6J9A0002.CR2
Rename 6H9A0003.CR2 6J9A0003.CR2
Rename 6H9A0004.CR2 6J9A0004.CR2
to
Rename 6H9A0085.CR2 6J9A0085.CR2

Any help would be gratefully received.

Andrew Greig
