I did read your tutorial. I'm not looking to execute a shell, I'm looking to execute a single command, however sudo requires a PTY. So while I do see that I can request a PTY when requesting a shell, I'd like to request a PTY while exec'ing a single command. Like I said in my original post, it's the same behavior as ssh -t <host> <program name>
