Pre-Type in Powershell - powershell

Question

I am doing some kubernetes hands-on and i am using kubectl in Powershell on a minikube cluster.
I found myself many times tired of having to type
kubectl do this
and then
kubectl do that
Is there any way to set Powershell to pretype kubectl after each press of Enter?

You can hijack the CommandNotFoundAction handler to "default" to kubectl commands when you enter a term that otherwise fails to resolve:
$ExecutionContext.InvokeCommand.CommandNotFoundAction = {
param([string]$CommandName, [System.Management.Automation.CommandLookupEventArgs]$evtArgs)
$kubectlCommands = -split 'annotate api-resources api-versions apply attach auth autoscale certificate cluster-info completion config cordon cp create debug delete describe diff drain edit exec explain expose get kustomize label logs patch plugin port-forward proxy replace rollout run scale set taint top uncordon version wait'
if($CommandName -in $kubectlCommands){
$evtArgs.CommandScriptBlock = {
& kubectl $CommandName #args
}.GetNewClosure()
$evtArgs.StopSearch = $true
}
}
This will cause PowerShell to execute kubectl whenever the command name entered matches a kubectl command.
Beware this only works as a last resort - cp something somewhere will never execute kubectl cp something somewhere because cp can be resolved as a command name natively in PowerShell.
