A script to switch kubectl context easily. For example by creating this file in "/usr/local/bin/context" you can switch context easily by executing "context" in console on any place.

kubectl-context-switch.sh

#!/usr/bin/env bash

CONTEXTS=`kubectl config get-contexts -o name | sort`

# Save current IFS
SAVEIFS=$IFS
# Change IFS to new line.
IFS=$'\n'
CONTEXTS=($CONTEXTS)
# Restore IFS
IFS=$SAVEIFS

echo -e "\nselect context: (current context: `kubectl config current-context`)\n"
select CONTEXT in "${CONTEXTS[@]}"
do
    echo ""
    kubectl config use-context $CONTEXT
    break;
done;
