One Liner to download the latest release from your GitHub repo

One Liner to download the latest release from your GitHub repo.md

LOCATION=$(curl -s https://api.github.com/repos/<YOUR ORGANIZTION>/<YOUR REPO>/releases/latest \
| grep "tag_name" \
| awk '{print "https://github.com/<YOUR ORGANIZATION>/<YOUR REPO>/archive/" substr($2, 2, length($2)-3) ".zip"}') \
; curl -L -o <OUTPUT FILE NAME> $LOCATION

for example:

LOCATION=$(curl -s https://api.github.com/repos/gvenzl/csv2db/releases/latest \
| grep "tag_name" \
| awk '{print "https://github.com/gvenzl/csv2db/archive/" substr($2, 2, length($2)-3) ".zip"}') \
; curl -L -o csv2db.zip $LOCATION

Here is how it goes:

LOCATION=$(...)

stores the output of all the commands in the brackets in the variable $LOCATION

curl -s https://api.github.com/repos/gvenzl/csv2db/releases/latest

gets the latest release from your repository, in my case github.com/gvenzl/csv2db

grep "tag_name"

grabs the tag name of the latest release (e.g. v1.0.0)

awk '{print "https://github.com/gvenzl/csv2db/archive/" substr($2, 2, length($2)-3) ".zip"}'

prints "https://github.com/gvenzl/csv2db/archive/" v1.0.0 ".zip" --> "https://github.com/gvenzl/csv2db/archive/v1.0.0.zip"

Now the $LOCATION is set to that string.

curl -L -o csv2db.zip $LOCATION

invokes cURL and downloads $LOCATION into csv2db.zip. The -L parameter is important so that cURL follows the URL, i.e. redirect.
