[digiKam-users] execute shell command on batch of images

[Marc Palaus]

Hi, It's definitely possible because I did that in the past, in order to 
correct some xmp metadata in some pictures.

That was a few years ago, but I remember it worked.

Basically, I created a bash script with the commands. Since we are 
working with several files, I created a loop like this one and put the 
desired command inside:

#!/bin/bash
echo "This is a sample script to be launched from Digikam"
# it just outputs the filenames
for var in "$@"
do
     echo "Processing file $var"
     #exiftool -XMP:All -TagsFromFile @ -XMP:all "$var" # Your command 
goes here. The picture filename is the $var variable.
done

Then, in Digikam, select the pictures to which you want to apply this 
command, right click, Open With..., Other, and in the prompt type:

xterm -hold -e /path/to/script/digikam_test_script.sh %U

You can use other terminal programs instead of xterm, of course, but 
then you have to figure out how to pass a command to it (for instance, 
in gnome-terminal it was something like: /usr/bin/gnome-terminal -- 
/path/to/script/digikam_test_script.sh.sh %U )

I hope it helps,

Marc
