Posted by

The script below will take a filename eg: DSCN0001.JPG, extract the “Image Created” metadata and rename the original file to something like 2006-03-23_DSCN00001.JPG and it will do it automatically for you.

#! /bin/shfunction usage() {if [ $# -ne 1 ]; then    echo "ExifDater - version 0.1 - March 23 2006"    echo "El-Lotso ”    echo “This  is  free  software;  see the source for copying conditions.”    echo “There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR”    echo “A PARTICULAR PURPOSE.”    echo    echo “ExifDater utilises the exiftags( http://johnst.org/sw/exiftags/)”    echo “program to sequentially extract the image creation date from”    echo “JPEG EXIF headers.”    echo    echo “Usage:”    echo “$0 /path/to/jpg/directory”    exit 0fi}function exiftimexist(){which exiftime > /dev/null 2>&1if [ $? -ne 0 ]; then    echo    echo “Unable to locate exiftime binary”    echo “Please make sure it is installed and is in your path.”    echo    exit 0fi}function gotodir(){cd $1 > /dev/null 2>&1if [ $? -ne 0 ]; then    echo    echo “Directory does not exists”    echo “Please try again.”    echo    exit 0fi}function jpgexist(){find . -iname “*.jpg” -type f >/dev/null 2>&1if [ $? -ne 0 ]; then    echo    echo “There are no JPEG pictures in this directory”    echo “Please try again.”    echo    exit 0fi}function myexifdater(){for i in *.jpgdo    create_date=`exiftime “$i” 2>&1 | grep -i image created | cut -d” ” -f3 | sed -e ’s/:/-/g’`    if [ “$create_date” == “” ]; then        echo -e “SKIPPING IMAGE $i \t\t\t [NO EXIF DATA FOUND]”        continue    fi    echo -n Processing Image $i Created on $create_date    do_rename=$( echo $i | sed -e ’s/(.*)/mv “&” “‘$create_date’_1″/g’|sh)    echo -e \t[DONE]done}usage $1exiftimexistgotodir $1jpgexistmyexifdater
