A banglist for falling back to DuckDuckGo without needing to hit their servers.
Courtesy of ddg-bangs and the following command:
curl -s 'https://raw.githubusercontent.com/zmwangx/ddg-bangs/master/data/bangs.json' | jq -r '[. | .bang + " " + .url] | join("\n")' > duckduckgo.bangs
Note that at present the bangs are a few years out of date (using the data in the linked repo), but most of them are still valid.
