如何在 Go 的單一 Shell 實例中順序執行多個命令？

// Run multiple commands in the same shell instance
func runCommands(commands []string) error {
    // Create a pipe for controlling the shell's standard input and output
    reader, writer, err := os.Pipe()
    if err != nil {
        return err
    }
    defer reader.Close()
    defer writer.Close()

    // Start the shell command
    cmd := exec.Command("/bin/sh")
    cmd.Stdin = reader
    cmd.Stdout = writer

    // Start the command and wait for it to finish
    if err := cmd.Start(); err != nil {
        return err
    }
    if err := cmd.Wait(); err != nil {
        return err
    }

    // Write each command to the shell's standard input
    for _, command := range commands {
        if _, err := writer.Write([]byte(command + "\n")); err != nil {
            return err
        }
    }

    // Close the pipe to signal the end of input
    if err := writer.Close(); err != nil {
        return err
    }

    // Read the output from the shell command
    output, err := ioutil.ReadAll(reader)
    if err != nil {
        return err
    }

    // Return the output
    return nil
}
