• Use curl to get the JSON response for the latest release
• Use grep to find the line containing file URL
• Use cut and tr to extract the URL
• Use wget to download it

curl -s https://api.github.com/repos/jgm/pandoc/releases/latest \
| grep "browser_download_url.*deb" \
| cut -d : -f 2,3 \
| tr -d \" \

statico.link short URLs

Why? I wanted an easy way to paste URLs that I use and share a lot.

How? It's just a domain plus a big list of urls (see links.conf) which I edit with a script (see links.sh)

Also: People kept asking for an index page, so I made one (https://github.com/statico/statico-link-list). I'll add social media previews when I can get it to work.
