One Liner to Download the Latest Release from Github Repo

One Liner to Download the Latest Release from Github Repo.md

• 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 \" \
| wget -qi -

/latest did not contain a browser_download_url for me, so I had to go a different route:

curl -s https://api.github.com/repos/Koenkk/zigbee2mqtt/releases/latest \
| grep  -m 1 '"url":' | cut -d : -f 2,3 | tr -d \" | sed 's/,*$//g' \
| xargs -n1 curl -s | grep tarball_url | cut -d : -f 2,3 | tr -d \" | sed 's/,*$//g' \
| xargs -n1 curl -L -o "latest_z2m.tar.gz"

1. download the latest json, and from that get the url of the actual latest release json
2. download the release json which does have a download url, called 'tarball_url'
3. download the tarball_url

In the first two steps the url is extracted from the json line by cleaning it up with grep, cut, and sed.
xargs strips the space and feeds the extracted clean URL to curl again.
The final curl also sets the desired filename for the latest release.
