I was tired of managing multiple versions of modules installed in my powershell
When multiple version of a module are installed, powershell sometimes call the wrong version of the module and end up with a command not found in the old version.
Here is a function to Verify, uninstall, install and upgrade powershell modules:

# module verify, update or get

param($modulearr01, $versionminimumarr01, $versionupgradetolatestarr01, $verbosesub01)

$found01 = 0
$foundsameversion01 = 0
foreach($module02 in $modules02)
{
### find module in installed modules
if($module02.name -eq $module01)
{

$msg01 = "Module found...: " + $module02.name + " " + $module02.version.tostring()
if($verbosesub01 -eq 1){write-host $msg01 -ForegroundColor Yellow}
