Linux および macOS でプログラムを TTY のように見せかけるにはどうすればよいですか?

package main

import (
    "io"
    "log"
    "os"
    "os/exec"
    "runtime"
)

func main() {
    // Get the current operating system.
    osName := runtime.GOOS

    // Create a master pty.
    master, err := os.OpenFile("/dev/ptmx", os.O_RDWR, 0)
    if err != nil {
        log.Fatal(err)
    }

    // Get the slave pty name.
    slaveName, err := ptsname(master)
    if err != nil {
        log.Fatal(err)
    }

    // Fork a child process.
    child, err := os.ForkExec("/bin/sh", []string{"sh", "-c", "ls -la"}, nil, slaveName, master, master)
    if err != nil {
        log.Fatal(err)
    }

    // Close the master pty.
    master.Close()

    // Read output from the slave pty.
    buf := make([]byte, 1024)
    for {
        n, err := os.Read(child, buf)
        if err == io.EOF {
            break
        }
        if err != nil {
            log.Fatal(err)
        }
        if osName == "linux" {
            // Remove carriage return (CR) characters.
            buf = buf[:n-1]
        }
        os.Stdout.Write(buf)
    }

    // Wait for the child process to exit.
    child.Wait()
}

go build -o ttypretend main.go

./ttypretend
