You should create a While loop with a condition of “not ‘q’” and then inside the While, type out your list of options 1-5 to pick from, add a read-host line to get the user’s choice, then create a Switch statement to tell the script where to go.

$answer = $null
While ($answer -ne 'q')
{
   Write-Host '1. do this'
   Write-Host '2. do that'
   Write-Host '3. do this and that'
   Write-Host '4. Other'
   Write-Host '5. Quit'
   $answer = Read-Host 'Please select an option'
   Switch ($answer)
   {
       '1' {'command or function call for option 1'}
       '2' {'command or function call for option 2'}
       '3' {'command or function call for option 3'}
       '4' {'command or function call for option 4'}
       '5' {exit}#or possibly return depending on what else you are doing
       Default {Write-Host 'Input not understood, exiting'; Exit;}
   }
}#end While

Thank you very much for your help on this one this is what I wanted.
But I will need to add two more things.
Currently when I select the option script will run and return to main menu.
What I would like to change is:
When I select the option it will run script and after that I will get the message:
“Press Any button to continue…”
After pressing any button this can return to main menu
Anothre thing I would like to add is sub-menu so I can select first cathegory and under that category I will have different options to run. When I enter wrong section possibility to return to main menu.

Thanks
Raf

To make it ask to press any key to continue, you can just add a ‘Pause’ at the end of the while statement.

The sub menu structure would be the same as the top level, just nested inside of the switch statement. You could also accomplish this with If statements and nesting those, however I prefer switch statements when dealing with more than a simple Y/N answer.

Here is an example of one of my scripts where I did something similar to what you are trying to achieve a while back. You might be able to get some ideas from it.
