In PowerShell (PS) you can use Aliases wich are short name of cmdlets, command, function, script, file or executable.
You can get all PS aliases with this cmdlet:
You can create/change your own aliases, for example:
Set-Alias -Name ping -Value Test-NetConnection
Now you can use ping instead Test-NetConnection
When the session is end you lost all your aliases, so is a good practice to save your aliases in a script or file and import them when you start a new session in PS.
