Explanation

To execute another Powershell script file within a Powershell script,

• Method #1 - run the hard coded script file

  .\test1.ps1

• Method #2 - run the script file name stored in a variable where the script location can be decided at runtime.

  $ps_file = "$PSScriptRoot\test1.ps1" & $ps_file

Use case

• If you are managing multiple servers and each has a slightly different setup, you may want to have different script files for different servers.
• If you are managing multiple applications that require sophisticated maintenance scripts.
• Some scripts were developed by third parties and you don't want to merge their codes into yours.
