Uninstall all SharePoint 2010 solutions from PowerShell

Uninstall all SharePoint 2010 solutions through PowerShell in order to demonstrate.        I often need to demolish and rebuild the SharePoint 2010 environment.        What I often need to do is remove all of the SharePoint solutions installed in the demo development environment. Here is the PowerShell script. It saves me a lot of time. I hope I can help you, too.

Script:

function uninstall-allspsolutions {    param (        [switch] $Local,        [switch] $Confirm    )   Start-spassignment-global;  foreach ($solution in (get-spsolution | Where-object {$_. Deployed}) {    write-host "uninstalling solution" $solution. Name;    if ($solution. Deployedwebapplications.count-gt 0) {      uninstall-spsolution $solution –allwebapplications-local: $Local-Confirm: $Confirm;    } else {      uninstall-spsolution $solution-local: $Local-confirm: $Confirm;    }    Do {      Start-sleep 5;      $solution = Get-spsolution $solution;    } while ($solution. Jobexists-and $solution. Deployed)   }   Stop-spassignment-global;} function remove-allspsolutions {    param (        [switch] $Confirm    )     get-spsolution | Where-object {!$_. Deployed} | Remove-spsolution-confirm: $Confirm}

Usage: Suppose you save the script to a file, say Remove-allspsolutions.ps1, and then call it in PowerShell, remember to write it in front:

. \remove-allspsolutions.ps1

You can use the following command to uninstall the solution for all deployments:

Uninstall-allspsolutions-confirm

and remove them:

Remove-allspsolutions-confirm
