Execution some Functions in Powershell Script

Question

Hi there,

I need to write a script in which I need to define different functions. In addition, the script must have a menu in which to choose which function to perform. I wrote the following script:

# Main menu, allowing user selection  
    function Show-Menu  
    {  
         param (  
               [string]$Title = 'Choose Which  to Start'  
         )  
         cls  
         Write-Host "================ $Title ================"  
          
      Write-Host "1: Press '1' to Stop LAGOServvices"  
      Write-Host "2: Press '2' to Start LAGOServvices"  
      Write-Host "3: Press '3' to Clean Temp-, Logs-, LocalhostFolders"  
      Write-Host "4: Press '4' to Start to Test LAGOWebsSrvices"  
      Write-Host "5: Press '5' to Restart LAGOServices"  
      Write-Host "6: Press '6' to Update LAGOServices"  
        
      Write-Host "Q: Press 'Q' to quit."  
    }  
      
    #Functions go here  
      
    Function StopLAGOServvices {  
     }  
       
    Function StartLAGOServices {  
    }  
      
    Function CleanTempfolder {  
     }  
      
    Function TestWebservices {  
    }  
      
    Function RestartLAGOServices {  
    }  
    Function UpdateLAGOServices {  
     }  
      
    #Main menu loop  
    do  
    {  
         Show-Menu  
         $input = Read-Host "Please make a selection"  
         switch ($input)  
         {  
               '1' {  
                    cls  
                    StopLAGOServvices  
               } '2' {  
                    cls  
                    StartLAGOServices  
               } '3' {  
                    cls  
                    CleanTempfolder  
        } '4' {  
     cls  
     TestWebservices  
        } '5' {  
     cls  
     RestartLAGOServices  
        } '6' {  
     cls  
     UpdateLAGOServices  
               } 'q' {  
                    return  
               }  
         }  
         pause  
    }  
    until ($input -eq 'q')  

This work and can choose option 1, 2, 3 etc. When a choose 1 is executed first function. I want to defined for example, function 5 which brings all other function togheter and execute all other. Something like this:
Function RestartLAGOServices { Function Stop LAGOServvices + Funcction Start LAGOServvices + Fuction Clean Temp-, Logs-, LocalhostFolders + Function Test LAGOWebsSrvices"}.
Can i use parameter for this purpose? For example:
$parameter = @(stop, start, restart, update)
if ($parameter -like start) { start Function StartLAGOServvices }
elseif ($parameter -like stop ) {stop Function Function StopLAGOServvices }
One more thing:
How define in menu, if i choose nothing it will be automatic continue to execute some script?

Thanks to each of you who will help me!

Answer 1

See if this works:

# Main menu, allowing user selection
function Show-Menu {
    param (
        [string]$Title = 'Choose Which  to Start'
    )
    Clear-Host
    Write-Host "================ $Title ================"
    Write-Host "1: Press '1' to Stop LAGOServvices"
    Write-Host "2: Press '2' to Start LAGOServvices"
    Write-Host "3: Press '3' to Clean Temp-, Logs-, LocalhostFolders"
    Write-Host "4: Press '4' to Start to Test LAGOWebsSrvices"
    Write-Host "5: Press '5' to Restart LAGOServices"
    Write-Host "6: Press '6' to Update LAGOServices"

    Write-Host "Q: Press 'Q' to quit."
}

#Functions go here
Function StopLAGOServvices {
}
Function StartLAGOServices {
}
Function CleanTempfolder {
}
Function TestWebservices {
}
Function RestartLAGOServices {
    StopLAGOServvices
    StartLAGOServices
    CleanTempfolder
    TestWebservices
}
Function UpdateLAGOServices {
}

#Main menu loop
do {
    Show-Menu
    $input = Read-Host "Please make a selection"
    Clear-Host
    switch ($input) {
        '1' {StopLAGOServvices;break}
        '2' {StartLAGOServices; break}
        '3' {CleanTempfolder; break}
        '4' {TestWebservices; break}
        '5' {RestartLAGOServices; break}
        '6' {UpdateLAGOServices; break}
        'q' {break} # do nothing
        default{
            Write-Host "You entered '$input'" -ForegroundColor Red
            Write-Host "Please select one of the choices from the menu." -ForegroundColor Red}
    }
    Pause
} until ($input -eq 'q')

Answer 3

Hi RichMatheisen-8856,

thank you, it's works. Can you help me with something else.
I need to automate the process, but i have no idea how make this. May be when i use "switch with casesensitve parameter and array".

I can't just restart the services ... the script always does everything ...

I want to have a script that I can call with a parameter:
restart - restart services
stop - stop services
start - start services
clean - clean folders
test - test webservices
update - update

if I don't specify a parameter, restart is used automatically.

I need a big IF THEN ELSE ELSE around my script ...

If $ param1 = restart ...
Elseif $ param1 = stop ...
Elseif $ param1 = start ..

I can define function or define scripts 5-6 scripts for each value of process.

With powershel script with menu and function, user must log in and choose function start oder stop, oder restart etc.
I'm at a dead end and I don't know how to proceed. I would be really grateful if someone helped me.

Answer 4

I try to explain little more clearly.
I have a Script with diferent function:

 Function StopLAGOServvices {
     }
     Function StartLAGOServices {
     }
     Function CleanTempfolder {
     }
     Function TestWebservices {
     }
     Function RestartLAGOServices {
         StopLAGOServvices
         StartLAGOServices
         CleanTempfolder
         TestWebservices
     }
     Function UpdateLAGOServices {
     }

I want to can define parameter with switch, something this:

Param(
        [Parameter(Mandatory=$True)]
        [string]$StringParameter
    )

    Switch ( $Param )
    {
                  Start { Function StartLAGOServices }
                  Stop { … }
                  Restart { … }
                  Clean { … }
                  Update { … }
    }

I want to start script with task shedule for example 00:30 with option start "function startlago..." oder stop "function stoplago.."

Another option is to use 5 different scripts and when I select the appropriate parameter to run the corresponding script - restartlago.sp1

 Param(
            [Parameter(Mandatory=$True)]
            [string]$StringParameter
        )

        Switch ( $Param )
        {if ($Param -like Start) {
              start startlago.ps1
             }
          elseif ($Param -like Stop) {
               start stoplagp.ps1
             }
          elseif ($Param -like Clean) {
                start cleanfolder.ps1
             }
    }

When i set up the task in shedule task i need to specife the right command. For example: execute the script restartlgo.sp1 with option start at 23:00 and script execute "start startlago.ps1". When i want to setup execute the script restartlgo.sp1 with option stop at 23:00 and script execute "stop stoplago.ps1".

I hope this explanation is clearer.

Thank you advance all of yours!
