Powershell Function for getting number of minutes since file last written to

I'm looking to convert the following powershell code into a function.

Id like to be able to specify a path ($filePath) and receive the number of minutes since it was last written to. The below works perfectly well, but id like it as a function as it needs to be repeated multiple times.

  $file = get-item $filePath
  $date = Get-Date
  $fileDate = $file.LastWriteTime
  $duration = ($date - $fileDate)
  $mins = $duration.TotalMinutes
  $RoundedMinsSinceLastWritten = [math]::Round($mins,2)

When i call $RoundedMinsSinceLastWritten, I get the value that I need (the number of minutes to 2 decimal places). I don't know what to call when this is in a function.

The goal is to have the value inside a variable.

Turning a group of statements into a function is as easy as enclosing them in {} and prefix it with the function keyword and a function name:

function Get-FileAge {
  # code goes here...
}

Id like to be able to specify a path ($filePath)

So we'll need to declare a $FilePath parameter:

function Get-FileAge {
  param(
    [Parameter(Mandatory = $true)]
    [string]$FilePath
  )

  $file = Get-Item $filePath
  $date = Get-Date
  $fileDate = $file.LastWriteTime
  $duration = ($date - $fileDate)
  $mins = $duration.TotalMinutes
  return [math]::Round($mins,2)
}

See the about_Functions_Advanced_Parameters help file for more details on parameter declarations in PowerShell functions.
