/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"
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.
First I ever heard of
bashandshoptions effecting any command that isn't a builtin tobashandsh(apart from command parsing that is). I'm pretty good with shell (35+ years experience)... Please enlighten!
