ASP.NET Core API to execute bash comands on linux server

I am absolutely new to ASP.NET Core.

I want to send a GET-Request to my Linux server which is hosting my ASP.NET Core API to execute some bash commands and return the given output in my GET-Response.

I found a similar question: ASP.NET Core execute Linux shell command but I am not sure if the answer is really the solution for my problem neither how to use this package.

Is there a solution for this like:

[HttpGet]
public async Task<ActionResult<IEnumerable<TodoItem>>> GetTodoItems()
{
    bashOutput = BASHCOMMAND(whoami);
    return await bashOutput;
}

Or is there may a better way to execute commands on my linux server and return the value via API? It doesn't have to be ASP.NET Core.

Try this

 public static string Run(string cmd, bool sudo = false)
    {
        try
        {
            var psi = new ProcessStartInfo
            {
                FileName = "/bin/bash",
                Arguments = (sudo ? "sudo " : "") + "-c '" + cmd + "'",
                RedirectStandardOutput = true,
                UseShellExecute = false,
                CreateNoWindow = true,
                RedirectStandardError = true,
                RedirectStandardInput = true,
            };

            Process proc = new Process() { StartInfo = psi, };
            proc.Start();
            string result = proc.StandardOutput.ReadToEnd();
            proc.WaitForExit();

            if (string.IsNullOrWhiteSpace(result))
            {
                Console.WriteLine("The Command '" + psi.Arguments + "' endet with exitcode: " + proc.ExitCode);
                return proc.ExitCode.ToString();
            }
            return result;
        }
        catch (Exception exc) 
        {
            Debug.WriteLine("Native Linux comand failed: " + cmd);
            Debug.WriteLine(exc.ToString()); 
        }

        return "-1";
    }
