Bulk processing using gpt

Someone please help me with GPT for bulk processing where do we get scripts for various operations in SNAP.?

Thanks in advance

You create the scripts yourself in the graph builder and save them as XML files.

thank you ABraun. Now I understood how to work with gpt. but can you share me, if you have some links/videos for doing batch processing? iterations in snap commandline for processing multiple scenes?

I have basic knowlege on python.

What about the second link?
