I know most .NET programs use Console.IsOutputRedirected to check if they are in a terminal. When running a process with CliWrap, the output of that property will be true. You can fake a terminal by wrapping it instead -- i.e. instead of Cli.Wrap("foo") do Cli.Wrap("/bin/sh").WithArguments(...). In this case, the output of the underlying process (launched by sh) will not be considered redirected.
