pass multiple commands in the processStartInfo argument

[NIlton_07]

Hello everyone !

I'm running a proof of concept - POC on a Linux machine and I need to pass multiple commands in the processStartInfo argument,

unfortunately all the attempts I made were not successful.

Below is the code and I implemented it (I'm using Aspnet.core 5 - using System.Diagnostics):

command[0] = "ping" - IT IS BEING PASSED DYNAMICS

System.Diagnostics.ProcessStartInfo StartInfo = new System.Diagnostics.ProcessStartInfo($"{comando[0]}");

StartInfo.Arguments = "\"8.8.8.8;ls -ls\"";

System.Diagnostics.Process.Start(StartInfo);

one of the errors that occurs:

1) ping: 8.8.8.8;ls -ls: Unknown name or service

2) fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]

An unhandled exception has occurred while executing the request.

Could someone please tell me what I'm doing wrong?

Note: I need to pass the command as the arguments dynamically, I use two variables for this. in the example above the

Argument is set and I'm just passing the command dynamically, but I'll also need to pass the arguments

dynamically, passing both dynamically also occurs error.

One more detail I also used the filename and UseShellExecute the same problem occurred.

StartInfo.UseShellExecute = true;

StartInfo.FileName = "../bin/bash";
