How to get the current user of the Ubuntu system in Asp .Net core 2.1?

Question

I'm having a requirement to identify the current logged in user in Ubuntu system. In windows I can use

System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();

to get the username. I'm confused how to do that for Linux. Any suggestions?

I want the current logged in user in the controller.

public ControllerName(IHostingEnvironment hostingEnvironment)
        {
            _hostingEnvironment = hostingEnvironment;
            webRootPath = _hostingEnvironment.WebRootPath; 
            var user = User.FindFirst(ClaimTypes.Name).Value;/* System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString(); */
        }

But User is returning null always.

Can you share more details code of where do you want to get the current logged in user? — TanvirArjel

@TanvirArjel No. I'm not using it. In that case is there any other way to get the user name? — Sruthi Varghese

Oh! then how do you storing logged-in user information in session? What is your logged in mechanism? — TanvirArjel

If you just want the user name:

Environment.UserName

I solved the problem by executing terminal command whoami from the .Net core application.

You can refer the below links for some idea.

1)run bash command from .NetCore with arguments
