I do not endorse or support the use of this software to access illegal material. This project is for educational purpouses only.
Simply feed a JSON file to the run.sh script. It will parse the JSON file using gen_sh.py which generates a list of bash commands to download files and then uses xargs to run downloads in parallel.
./run.sh ./im0004.json
