15 May 2007 Shell scripts for archiving digital photos in directories by date

The fact that most digital cameras store the shooting dates inside JPEG files in the EXIF format makes it possible to automatically archive the photos by date right after they are downloaded, which is exactly what the scripts below do.

Here’s an example of a directory tree they create:

1999
  1999-07
     1999-07-14
       IMG_48324.JPG
       IMG_48325.JPG
       IMG_48326.JPG
     1999-07-17
       IMG_48331.JPG
       IMG_48333.JPG
       IMG_48334.JPG
       IMG_48337.JPG
  ...etc...

move-digiphotos
This bash script (move-digifotos) scans EXIF tags from .JPG files in current directory with metacam, creates necessary directories under $BASEDIR and moves the files in them:

#!/bin/bash

# Reads EXIF creation date from all .JPG files in the
# current direcotry and moves them carefully under
#
#   $BASEDIR/YYYY/YYYY-MM/YYYY-MM-DD/
#
# ...where 'carefully' means that it does not overwrite
# differing files if they already exist and will not delete
# the original file if copying fails for some reason.
#
# It DOES overwrite identical files in the destination directory
# with the ones in current, however.
#
# This script was originally written and put into
# Public Domain by Jarno Elonen  in June 2003.
# Feel free to do whatever you like with it.

  BASEDIR=/home/jarno/gfx

find -maxdepth 1 -name "*.JPG" | while read x; do
  DATE=`metacam "$x" | \
    egrep "^[ \t]*Image Capture Date:" | \
    sed -r "s/Image Capture Date: ([0-9:]*).*/\1/"`
  if [ ! -z "$DATE" ];
  then
    YEAR=`echo $DATE | sed -r "s/([0-9]*):([0-9]*):([0-9]*)/\\1/"`
    MONTH=`echo $DATE | sed -r "s/([0-9]*):([0-9]*):([0-9]*)/\\2/"`
    DAY=`echo $DATE | sed -r "s/([0-9]*):([0-9]*):([0-9]*)/\\3/"`
    if [ "$YEAR" -gt 0 ] & [ "$MONTH" -gt 0 ] & [ "$DAY" -gt 0 ]
    then
      INSTDIR=${BASEDIR}/${YEAR}/${YEAR}-${MONTH}/${YEAR}-${MONTH}-${DAY}
      install -d "$INSTDIR"
      INSTFILE="$INSTDIR/$x"
      if [ -e "$INSTFILE" ] && ! cmp -s "$x" "$INSTFILE"
      then
        echo "WARNING: '$INSTFILE' exists already and is different from '$x'."
      else
        echo "Moving '$x'"
        cp "$x" "$INSTFILE"
        if ! cmp -s "$x" "$INSTFILE"
        then
          echo "WARNING: copying failed somehow, will not delete original '$x'"
        else
          rm -f "$x"
        fi
      fi
    else
      echo "WARNING: '$x' doesn't contain date."
    fi
  else
    echo "WARNING: '$x' doesn't contain date."
  fi
done

fetch-digiphotos
The fetch-digiphotos script fetches pictures from a camera through gphoto2 into a temporary directory under $TMPDIR, moves them with move-digiphotos and finally offers to delete them from the camera:

#!/bin/bash

# Downloads pictures from a digital camera using gphoto2,
# moves them with move-digiphotos.sh and optionally deletes
# them from the camera's memory.
#
# This script was originally written and put into
# Public Domain by Jarno Elonen  in June 2003.
# Feel free to do whatever you like with it.

TMPDIR=/home/jarno/gfx/tmp

if [ ! -d "$TMPDIR" ]; then
echo "*** Error: download directory '$TMPDIR' does not exist, aborting."
exit 1
fi
pushd "$TMPDIR" > /dev/null

gphoto2 -P
if [ $? != 0 ]; then
echo "*** error executing gphoto2, aborting."
popd > /dev/null
exit 1
fi

move-digiphotos

echo
echo -n "Delete pictures from camera? [y/N] "
read x
if [ $x == "y" ]; then
gphoto2 -D
fi
if [ $? != 0 ]; then
echo "Warning: error executing gphoto2."
popd > /dev/null
exit 1
fi

echo "Done."
popd > /dev/null
