Goで実行出力をリアルタイムでロガーにリダイレクトする方法は?

import (
    "bufio"
    "log"
    "os/exec"
)

func main() {
    cmd := exec.Command("yes")

    // Create a pipe to connect the command's stdout to the logger
    stdout, err := cmd.StdoutPipe()
    if err != nil {
        log.Fatalf("Failed to create stdout pipe: %v", err)
    }

    // Start the command
    if err := cmd.Start(); err != nil {
        log.Fatalf("Failed to start command: %v", err)
    }

    // Create a buffered reader to read the output line by line
    in := bufio.NewScanner(stdout)

    // Read the output and log it in real-time
    for in.Scan() {
        log.Printf(in.Text())
    }

    if err := in.Err(); err != nil {
        log.Printf("Error reading command output: %v", err)
    }
}
