A library provides an interface for a unix PTY/TTY.
It aims to work on all major Unix variants.
The library was developed as a backend for a https://github.com/zhiburt/expectrl.
If you're interested in a high level operations may you'd better take a look at zhiburt/expectrl.
use ptyprocess::PtyProcess;
use std::io::{BufRead, BufReader, Result, Write};
use std::process::Command;
fn main() -> Result<()> {
// spawn a cat process
let mut process = PtyProcess::spawn(Command::new("cat"))?;
// create a communication stream
let mut stream = process.get_raw_handle()?;
// send a message to process
writeln!(stream, "Hello cat")?;
// read a line from the stream
let mut reader = BufReader::new(stream);
let mut buf = String::new();
reader.read_line(&mut buf)?;
println!("line was entered {buf:?}");
// stop the process
assert!(process.exit(true)?);
Ok(())
