Shell script to call python program with changing arguments

I have images in a sub-folder. Let's the folder images

I have a python program which will take image arguments from the folder one by one, the images are named in sequential order (1.jpg , 2.jpg, 3.jpg and so on).

The call to the program is : python prog.py 1.jpg

What will be a shell script to automate this ?

Please ask for any additional information.

cd IMG_DIR
for item in [0-9]*.jpg
do
 python prog.py $item
 echo "Item processed : $item"
done

You can also pass image dir as a shellscript argument

You could do them all in parallel very simply with GNU Parallel like this:

parallel python prog.py ::: images/*.jpg

Or, if your Python writes to the current directory:

cd images
parallel python prog.py ::: *.jpg

Try this from the folder that contains images/:

for i in images/*.jpg; do python prog.py $i done
