If you run your PowerShell scripts on Windows, you can use the taskbar button as a progress indicator. All you need is install this module:
Install-Module -Name PsoProgressButton -Scope CurrentUser
Next, you can run the command below to set the progress bar inside your taskbar button to a value between 0 and 100. This sets the indicator to 50%:
PS> Set-PsoButtonProgressValue -CurrentValue 50
To turn the indicator off again, run this:
PS> Set-PsoButtonProgressState -ProgressState NoProgress
