        $password =  ConvertTo-SecureString $AzuresecretValue -AsPlainText -Force; 
        $VMResourceGroup = "npd-test-rg01";
        #Connecting to the Azure VM using the Service Principle
        $pscredential = New-Object -TypeName System.Management.Automation.PSCredential($AzureApplicationID, $password);
        Connect-AzAccount -ServicePrincipal -Tenant $AzureDirectoryID -Credential $pscredential | Out-null;
        
        $VMList = Get-AzVm -ResourceGroupName $VMResourceGroup -Status;

        ForEach($VM in $VMList) {

              if ($VM.Name -eq "npd-test-app01"){
                    Write-Host "Test Machine traced!!!"
                }
              else {
                continue;
              }

        }

}

function triggerShellScript () {
        $AzuresecretValue    = "<AzureSecret>";
        $AzureApplicationID  = "<AzureApplicationID>";
        $AzureObjectID       = "<AzureObjectID>";
        $AzureDirectoryID    = "<AzureDirectoryID>";
        $AzureUserName       = "SVCUSER";
        $AzureSubscriptionID = "<AzureSubscriptionID>";

Answer 1

You can run the Shell Script in OS Linux using the Azure Cloud Shell.

Step 1: Created a file script.sh using command code script.sh and pasted the command and save and close editor.

Step 2: use the below command to run the above Script in your VM.

Invoke-AzVMRunCommand -ResourceGroupName '<myResourceGroup>' -Name '<myVMName>' -CommandId 'RunShellScript' -ScriptPath '<pathToScript>'
