Basic Idea and Challenge

PowerShell is all about automation, and creating a loop in PowerShell that creates an array of numbers is easy, add a prefix to that and hey you have an array

   
1..10 | ForEach-Object {"LC-SRV-" + $_}    

The output.

The Magical -F

But, there is a small issue, the names of the server names that i need to be generated is kind of correct, but wrong, or “almost” great, I need the length to be the same. That can be fixed by using the magical –f.

   
1..10 | ForEach-Object {"LC-SRV-{0:D3}" -f $_}    

The Output.

The Function

So, now it looks the way I need it to be, and if you need to use it often, let’s create a function for it.

   
Function Create-VIAComputerName{    
Param(    
$ComputerPrefix,    
$LowNumber,    
$HigNumber    
)
  
$Servers = $($LowNumber..$HigNumber| ForEach-Object {"$ComputerPrefix{0:D3}" -f $_})   
Return $Servers    
}
  
Create-VIAComputerName -ComputerPrefix LC-SRV- -LowNumber 1 -HigNumber 64   

The Output.
