The first time I run it, I get the menu, make a "1" selection (get-mailbox), it pauses, but I get no results. I have a problem with my script, which matches closely to what is above. When ran with the title parameter set to 'My Menu', it will look like this: Show-Menu –Title 'My Menu' This is a simple function that first clears the console and then writes a few lines to it. Write-Host "3: Press '3' for this option." Write-Host "2: Press '2' for this option." Write-Host "1: Press '1' for this option." #Powershell display menu to user codeThis menu consists of two main components: a function that displays the menu, and a switch statement that takes the input and directs the code which way to go, depending on the selection. #Powershell display menu to user how toLet’s go over how to build a rudimentary interactive menu in the PowerShell console. We will explain it using the “ -NoEnumerate” and without using “ -NoEnumerate“.Constructing an interactive menu that allows the user to select between different options is a great way to build scripts for less PowerShell-savvy people, or it can simply be used as a kind of input gateway to a lot of the functionality that you’ve already built in PowerShell. If we use “ -NoEnumerate“, then it will display 1 in the count field. This PowerShell cmdlet will count the total number of expressions used in an echo command, and it will return 3 as a count. We have taken three integers and printed them using “ echo” in a PowerShell script: we are piping a PowerShell cmdlet “ Measure-Object“. Let’s explain this parameter with the help of an example: The -NoEnumerate parameter helps you to get a single count of the terms used in the echo command: A dropdown menu will be activated, which contains the supported parameter:įor instance, the echo/Write-Output command prints the output as an individual expression. Type “ Write-Output” in the scripting pane of the “ PowerShell ISE“, and then write hyphen (-). However, there are other multiple operations that we can perform using the echo command in PowerShell, such as using parameters to manipulate the output as per your requirements.Įcho supports various parameters, as shown below. It means that the string has passed through the pipeline. The command will display the members of the System.String class of PowerShell. Open the script, and write the following code: First, create a PowerShell script, and we have named it “ hello.ps1“. The echo command is used to display the output on the output console of PowerShell ISE.įor instance, you want to print “ Hello World” using the echo command in PowerShell. The difference explained in the above examples depicts that “ echo” and “ Write-Host” can be used alternatively, but “ Write-Host” can be used only when you want to get the output on the console. Write-HostĮxample 1 shows that only the “ Write-Host” does not pipe the function, and in Example 2, the Write-Host cmdlet provides the result but is not in order. The “ Get-Command” command is used to print all the Alias, Functions, and PowerShell cmdlets on the system. In these scripts, we have created a variable in which the “ Get-Command” cmdlet is saved. We have created three scripts and named PO_Host, PO_Out and PO_echo, for “ Write-Host”, “ Write-Output”, and “ echo”, respectively. We will explain another example that will enlighten the difference between “ echo”, “ Write-Host”, and “ Write-Output”: You have to change the characteristics of “ Write-Host” as we did in the 8th line of the script. Note: the “ echo” and “ Write-Output” have fetched the function. Find your script, and once it is loaded, press “ F5” to run: \“, this symbol will open a dropdown menu that shows all the files inside the directory. To run the script, jump to the directory where you have saved the script. The script view of the code is given below: Write-Host "this is a test" -ForegroundColor black -BackgroundColor White
