Rename photo files

I needed to re-arrange my collection of photo files. To standardise the file naming, I used the Linux rename utility, part of util-linux.

find | grep AUT | xargs rename AUT aut
find | grep DSC | xargs rename DSC dsc 
find | grep IMG | xargs rename IMG img
find | grep JPG | xargs rename JPG jpg
find | grep Mov | xargs rename Mov mov
find | grep MOV | xargs rename MOV mov
find | grep THM | xargs rename THM thm
find | grep TIM | xargs rename TIM tim

To split files up by date, I hacked up some Perl, pushdir.pl that looked at the EXIF data (if any) for the creation time or used the mtime of the file, and moved the file to a directory yyyy-mm-dd, creating it if nexessary.

Rotating the image in a file changes the mtime of a file, but not its EXIF timestamp. Copying a file from a camera or memory card may or may not preserve the file creation time, or create funny capitalisation.
