18 May 2007 Fikse rett dato på bildefil ut i fra EXIF info
Av og til kopierer man bilder og da kan det hende bildefila får feil dato og tid for når bildet ble tatt. Kjør dette scriptet er for å rette dette igjen

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 # # $BASEDIR/YYYY/YYYY-MM/YYYY-MM-DD/ # # ...where 'carefully' means that it does not overwrite # differing files if they already exist and will not delete # the original file if copying fails for some reason. # # It DOES overwrite identical files in the destination directory # with the ones in current, however. # # This script was originally written and put into # Public Domain by Jarno Elonenin June 2003. # Feel free to do whatever you like with it. BASEDIR=/home/jarno/gfx find -maxdepth 1 -name "*.JPG" | while read x; do DATE=`metacam "$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 $TMPDIR, moves them with move-digiphotos and finally offers to delete them from the camera:
#!/bin/bash # Downloads pictures from a digital camera using gphoto2, # moves them with move-digiphotos.sh and optionally deletes # them from the camera's memory. # # This script was originally written and put into # Public Domain by Jarno Elonenin June 2003. # Feel free to do whatever you like with it. TMPDIR=/home/jarno/gfx/tmp if [ ! -d "$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

15 May 2007 Shell script for removing duplicate files
The following shell script finds duplicate (2 or more identical) files and outputs a new shell script containing commented-out rm statements for deleting them.
You then have to edit the file to select which files to keep – the script can’t safely do it automatically!
OUTF=rem-duplicates.sh;
echo "#! /bin/sh" > $OUTF;
find "$@" -type f -print0 |
xargs -0 -n1 md5sum |
sort --key=1,32 | uniq -w 32 -d --all-repeated=separate |
sed -r 's/^[0-9a-f]*( )*//;s/([^a-zA-Z0-9./_-])/\\\1/g;s/(.+)/#rm \1/' >> $OUTF;
chmod a+x $OUTF; ls -l $OUTF
Example output (rem-duplicates.sh)
#! /bin/sh #rm ./gdc2001/113-1303_IMG.JPG #rm ./reppulilta/gdc2001/113-1303_IMG.JPG #rm ./lissabon/01-01-2001/108-0883_IMG.JPG #rm ./kuvat\ reppulilta/lissabon/01-01-2001/108-0883_IMG.JPG #rm ./gdc2001/113-1328_IMG.JPG #rm ./kuvat\ reppulilta/gdc2001/113-1328_IMG.JPG
Explanation
- write output script header
- list all files recursively under current directory
- escape all the potentially dangerous characters with xargs
- calculate MD5 sums
- find duplicate sums
- strip off MD5 sums and leave only file names
- escape strange characters from the filenames
- write out commented-out delete commands
- make the output script writable and ls -l it

15 Apr 2007 Extract pictures from a VOB file using transcode
Sometimes it is useful to collect some pictures from some different DVD’s to a new one. But what to do if the original pictures are deleted now. You can use the following command to extract the pictures first.
transcode -x mpeg2 -i VTS_01_1.VOB -y im -F jpg -w 100
-F jpg, png, gif ==> picture format (default jpg)
-w number ==> quality for jpeg and compression-level/quality for png (for example 95, see “man transcode”)
Now you can choose and delete some and collect new with the described procedure at dir2slideshow.
