Auto-Declaring Alias Names for Functions

You probably know that PowerShell supports alias names for commands. But did you know that you can define alias names for PowerShell functions inside a function definition (introduced in PowerShell 4)? Have a look:

function Get-AlcoholicBeverage
{
    [Alias('Beer','Drink')]
    [CmdletBinding()]
    param()

    "Here is your beer."
}

The “official” name for the function is Get-AlcoholicBeverage, but this function is also available via the aliases “Beer” and “Drink”. PowerShell automatically adds these aliases when the function is defined:

 
CommandType     Name                                              
-----------     ----                                                                                       
Alias           Beer -> Get-AlcoholicBeverage                                                                               
Alias           Drink -> Get-AlcoholicBeverage
