Get node latest version for a major release

dotnet.sh

#!/bin/bash

MAJOR_VERSION=${1:-7}

# $1 => major release version (e.g. 6, 7)
dotnet_get_latest_version() {
    if [[ -n "$1" ]] ; then
        # Get latest by major version using jq
        curl -s https://api.github.com/repos/dotnet/core/releases | jq -r '.[].tag_name | select(. | startswith("v'"${1:-7}"'."))' | head -n 1 | sed 's/v//g'
    else
        # Get default latest
        curl -s https://api.github.com/repos/dotnet/core/releases/latest | jq -r .tag_name | sed 's/v//g'
