Similar to connecting to remote computer using WSManagement, how to do it through powershell terminal?

I have the following code to connect to the remote powershell and execute script on remote machine :
WSManConnectionInfo connectionInfo =newWSManConnectionInfo(false,"MachineName",5985,"/wsman", shellUri, credential);
using (Runspace runspace =RunspaceFactory.CreateRunspace(connectionInfo)){
                runspace.Open();
                using (PowerShell powershell =PowerShell.Create()){
                    powershell.Runspace= runspace;String file =@"C:\scripts\createUser.ps1";
                    powershell.Commands.AddScript(System.IO.File.ReadAllText(file));Collection<PSObject> results = powershell.Invoke();}}
How to execute the script in same way from powershell command prompt?
