Quick Script To Sort and Rename from EXIF Date

I wrote a quick bourne shell script to sort and rename the image files I recovered from my formatted memory stick. It requires the perl exifdump script that comes with the Image::Info module (not the python script by the same name). Since the last pre-format image I had was 8160, I started the recovered files at number 8161. The filenames will not be exactly right due to images that were deleted and retaken, but close enough.

The script was coded up quickly so there is no documentation or error checking.

#!/bin/sh
#

NUM=8161
PRE=DSC0
EXT=.JPG
TEMPLIST=`/usr/local/bin/mktemp /tmp/ds-rename.XXXXXX`
TEMPSORT=`/usr/local/bin/mktemp /tmp/ds-rename.XXXXXX`

for file in V*.[jJ][pP][gG]
do
echo "Processing ${file}..."
DATE=`/home/jlick/bin/exifdump ${file} 2> /dev/null | /bin/grep DateTimeOriginal | /bin/sed -e "s/.*DateTimeOriginal -> //"`
echo ${DATE} ${file} >> ${TEMPLIST}
done

echo "Sorting..."
/bin/sort ${TEMPLIST} > ${TEMPSORT}

for file in `/bin/sed -e "s/.* //" < ${TEMPSORT}`
do
echo "Renaming ${file} to ${PRE}${NUM}${EXT}..."
/bin/mv ${file} ${PRE}${NUM}${EXT}
NUM=`/bin/expr ${NUM} + 1`
done

/bin/rm -f ${TEMPLIST} ${TEMPSORT}
