pty

I have a program in Linux which refuses to run if its stdin/stdout is not a TTY (terminal device). Is there an easy-to-use tool which will create a PTY, start the program with the newly created TTY, and copy all data over stdin/stdout? The use case is not interactive, but scripting. I'm looking for the most lightweight solution, preferably not creating TCP connections, and not requiring too many other tools and libraries to be installed. Ignacio Vazquez-Abrams unbuffer , part of expect ( sudo apt-get install expect-dev on Ubuntu Lucid), can fool a program into thinking it's connected to a TTY.

I'm making a small ncurses application in Rust that needs to communicate with a child process. I already have a prototype written in Common Lisp. I'm trying to rewrite it because CL uses a huge amount of memory for such a small tool. I'm having some trouble figuring out how to interact with the sub-process. What I'm currently doing is roughly this: Create the process: let mut program = match Command::new(command) .args(arguments) .stdin(Stdio::piped()) .stdout(Stdio::piped()) .stderr(Stdio::piped()) .spawn() { Ok(child) => child, Err(_) => { println!("Cannot run program '{}'.", command);

I am trying to find a way in Python to run other programs in such a way that: The stdout and stderr of the program being run can be logged separately. The stdout and stderr of the program being run can be viewed in near-real time, such that if the child process hangs, the user can see. (i.e. we do not wait for execution to complete before printing the stdout/stderr to the user) Bonus criteria: The program being run does not know it is being run via python, and thus will not do unexpected things (like chunk its output instead of printing it in real-time, or exit because it demands a terminal to
