Extract all URLs from links

Goal: Collect every link target in a document, handy for a broken-link checker or a quick inventory of external references.

Prerequisites: None.

Query

.link.url

$ mq '.link.url' README.md

Input

Check out [mq](https://mqlang.org) and [GitHub](https://github.com).

Output

https://mqlang.org
https://github.com

Notes

• Want the link’s visible text instead? Use .link.value in place of .link.url. (.link.title is the separate, optional "title" attribute from [text](url "title") syntax, usually empty.)
• Default output is already one URL per line, so pipe it straight into xargs -I{} curl -sfI {} to check for broken links.
