[GRLUG] Set .jpg modified date/time from EXIF info?

[Raymond McLaughlin]

If you don't have a copy of jhead laying around the following bash
script might work for you. You need to substitute the correct year for
'2003' in this example. (In case word wrap mangling the do loop is 2 lines.)

  for i in $(ls *.jpg)
  do
    mdate=$(strings $i| grep 2003:| cut -d ':' -f 1,2,3,4| uniq| sed
s/://g|sed s/' '//)
    touch -t $mdate $i
  done

I hope this helps
