You need to modify the script according to your requirements. The below script does a check-in of all the documents forcefully in a document library. Similarly you could customize the script to check-out all the documents.

$listname = "testdoc"

$url = "http://spsite"

function approveContent ($w, $listName) {

  $list = $w.Lists |? {$_.Title -eq $listName}

  foreach ($item in $list.Items)

  {

       

        if(($item -ne $null) -and ($item.LockId -ne $null)) {

      $item.ReleaseLock($item.LockId)

    }

    if( $item.File -ne $null) { $itemFile = $list.GetItemById($item.ID).File }

    else { $itemFile = $list.GetItemById($item.ID) }

   

    if( $itemFile.CheckOutStatus -ne "None" ) {

      $itemFile.CheckIn("Automatic CheckIn. (Administrator)")

      if( $item.File -ne $null) { $itemFile = $list.GetItemById($item.ID).File }

      else { $itemFile = $list.GetItemById($item.ID) }

    }

   

  }

}

$site = Get-SPSite $url

foreach ( $web in $site.AllWebs )

{

approveContent $web $listname

}
