Normally in PowerShell if you want to report progress on a long running task, you’d use a progress bar using the Write-Progress cmdlet. That’s definitely the right way to do this, but what if you wanted a different way… for some reason? In the PowerShell Slack (invite yourself: slack.poshcode.org), I recently answered this question: “I want to write out ‘There are 3 seconds remaining. There are 2 seconds remaining.’ etc. until there are no seconds remaining and then keep going, but I don’t want them all to appear on the different lines. I basically just want the number to update.”
This gif shows what the question asker was after (except instead of counting up, they wanted a countdown).
