Merging Multiple kubeconfig Files into One

I obtained a new kubeconfig - kubeconfig_new from az aks get-crednetials, and I want to merge it into the existing ~/.kube/config. How should I do?

Backup existing kubeconfig

#!/bin/bash
cp ~/.kube/config ~/.kube/config-backup.$(date +"%Y%m%d-%H%M")

A one-line command merge

#!/bin/bash
# KUBECONFIG=~/Downloads/kubeconfig_a:~/Downloads/kubeconfig_b:~/.kube/config kubectl config view --flatten > merged.config


export KUBECONFIG=/Users/pichuang/ms-workspace/sunshine/air/kubeconfig_aks-ice-jpe:~/.kube/config
echo $KUBECONFIG
kubectl config view --flatten > ~/.kube/merged.config
mv ~/.kube/merged.config ~/.kube/config

Switch Difference Context

#!/bin/bash
kubectl config get-contexts
kubectl config use-context
kubectl config current-context
