|
|
You have got a digital camera and take a lot of pictures or you collect otherwise a lot of pictures? This may help you.
This are examples how to sort, rename oder do other thinks with your pictures based on width, height or other exif-data. First we need media-gfx/jhead. The small binary jhead printout a lot of informations about an (jpeg) picture.
Examples:
Code: | # jhead 1.jpg
File name : 1.jpg
File size : 53555 bytes
File date : 2004:10:19 11:46:11
Resolution : 1200 x 798 |
Code: | # jhead 100_0640.jpg
File name : 100_0640.jpg
File size : 1004144 bytes
File date : 2005:07:03 15:12:50
Camera make : EASTMAN KODAK COMPANY
Camera model : KODAK CX7330 ZOOM DIGITAL CAMERA
Date/Time : 2005:07:03 15:12:45
Resolution : 1524 x 2032
Flash used : No (auto)
Focal length : 5.6mm (35mm equivalent: 37mm)
Exposure time: 0.0040 s (1/250)
Aperture : f/5.6
ISO equiv. : 120
Whitebalance : Auto
Metering Mode: matrix
Exposure : Action program (based towards fast shutter speed) |
Now we can use this output in scripts.
I use find because I want process pictures in subdirectorys too.
Code: | find ./ -type f -iname '*.jpg' | while read file ; do
resolution=`jhead "${file}" | grep ^Resolution | cut -d ":" -f 2`
if [ "$resolution" != "" ] ; then # check if really resolution found
height=`echo $resolution | cut -d "x" -f 2 | sed -e "s/ //g"`
width=`echo $resolution | cut -d "x" -f 1 | sed -e "s/ //g"`
# here comes your lines to process the picture
fi
done |
For example you can use the following to ascertain the format of the picture
Code: | if [ $width -gt $height ] ; then
# landscape format
else
# portrait format
fi |
or you want to rename the picture? (width and height at first in the filename)
Code: | mv "${file}" "`dirname ${file}`/${width}x${height}_`basename ${file}`" |
or you want to rename the picture? (width and height at last in the filename)
(work only at case-sensitive suffix, here *.jpg, not at *.JPG)
Code: | mv "${file}" "`dirname ${file}`/`basename ${file} .jpg`_${width}x${height}.jpg" |
remove all pictures they are landscape format and width is smaller than 640 pixel
Code: | if [ $width -gt $height ] && [ $width -lt 640 ] ; then
rm "${file}"
fi |
move all pictures from one day in several directorys based on (exif-) date:
Code: | find ./ -type f -iname '*.jpg' | while read file ; do
date=`jhead "$file" | grep ^Date | cut -d ":" -f 2- | cut -d " " -f 2`
if [ "$date" != "" ] ; then # check if really date found
YY=`echo $date | cut -d ":" -f 1`
MM=`echo $date | cut -d ":" -f 2`
DD=`echo $date | cut -d ":" -f 3`
test -d "/destination/${YY}-${MM}-${DD}" || mkdir "/destination/${YY}-${MM}-${DD}"
mv "${file}" "/destination/${YY}-${MM}-${DD}"
fi
done |
Sorry for my bad english, you can read this post in german too
If you think it is usefull please post an comment (or your script).

some people on the ubuntu chan where discussing to find a error on this script and finnaly they find that in the end you type a [ for a {
Code: |
test -d "/destination/${YY}-${MM}-$[DD}" || mkdir "/destination/${YY}-${MM}-$[DD}"
mv "${file}" "/destination/${YY}-${MM}-$[DD}"
|
instead of
Code: |
test -d "/destination/${YY}-${MM}-$[DD}" || mkdir "/destination/${YY}-${MM}-$[b]{[/b]DD}"
mv "${file}" "/destination/${YY}-${MM}-$[b]{[/b]DD}"
|
if it can help.... (i'm begining in scripting )
this is a nice script |
