Bash script to fetch all mangas in Mangadex

md.sh

#!/bin/bash
set -ehv
mkdir -p md
time curl --retry 64 --doh-url https://cloudflare-dns.com/dns-query --compressed --http2 "https://api.mangadex.org/v2/title/[000001-090000]?include=chapters" -o "md/md_titles_#1.json"
time for ((j = 0; j < 9;)); do jq -Mc ".data?|objects" $(seq 0$((j))0001 0$((++j))0000|xargs printf "md/md_titles_%06i.json\n"); done | tee md_titles_data.json
time jq -Mc ".manga | {id, titles: [.title, .altTitles[]], blurbs: .description}" ../md_titles_data.json | ../md_titles.json

How can i make this work? How/where?

@Poederkindje Hi this is old code. The API changed a lot ever since the major update. You can find more information here. I will update my program when I have time.
