09 Apr 2007 md5sum av filer/bilder
For å sikre seg mot at filer er korrupt kan man benytte kommandoen md5sum
Windows
md5sum -b *.JPG > checksum.md5
Linux
Deretter kopierer man denne md5-fila til rett katalog i Linux og tester at disse filene er identisk vha MD5Sums, et grafisk Windows program.

13 Mar 2007 Script to download pictures from camera and rename them etc
1. download photos from camera and sort them by date of day in folders
2. remove possible duplicates if I did not erase camera images since last download
3. convert RAW/NEF images to a usable format
All this in one single click!
#!/bin/bash
# Change this to where to store Photos
target=/home/multimedia/Images
camera=”USB PTP Class Camera”
date=$(date –iso-8601)
mkdir -p $target/$date/tmp
cd $target/$date/tmp
# Get all photos from camera
gphoto2 –quiet –camera $camera –port usb: -P
# Do not replace photos that were already uploaded this same day
cp -u $target/$date/tmp/* $target/$date
rm -rf $target/$date/tmp
cd $target/$date
# auto-rotate using exif info
exifautotran *.JPG
# If photos were not erased from camera since last upload, remove duplicates
for i in *.{JPG,NEF}; do
for f in $(find $target -name $i ! -samefile $target/$date/$i); do
if md5sum $f | sed -e “s, .*/, ,” | md5sum –check; then
rm -f $i;
fi
done
done
# decode RAW images if not already done ?
# for i in *.NEF; do if [ ! -e $(basename $i .NEF).ppm ]; then dcraw -w $i; fi; done
# Show them!
gimv -d $target/$date
