Example

lets say you want to update your kubernetes objects, every time you changed your deployment or service config, you'd use awaitchange like this:

    while [ true ]
    do
        clear       # Clear terminal window
        kubectl apply -f deployment.yaml
        kubectl apply -f service.yaml

        awaitchange deployment.yaml service.yaml
    done

There is a shorthand for this, just use the --do flag an pass a script, that should be executed (in sh)

awaitchange deployment.yaml --do "kubectl apply -f deployment.yaml"
