我在弄清楚如何使用os / exec包运行多个命令时遇到了麻烦。我已经摸索了网络和stackoverflow，还没有找到任何适合我的案例。这是我的资料来源：

package main

import (
    _ "bufio"
    _ "bytes"
    _ "errors"
    "fmt"
    "log"
    "os"
    "os/exec"
    "path/filepath"
)

func main() {
    ffmpegFolderName := "ffmpeg-2.8.4"
    path, err := filepath.Abs("")
    if err != nil {
        fmt.Println("Error locating absulte file paths")
        os.Exit(1)
    }

    folderPath := filepath.Join(path, ffmpegFolderName)

    _, err2 := folderExists(folderPath)
    if err2 != nil {
        fmt.Println("The folder: %s either does not exist or is not in the same directory as make.go", folderPath)
        os.Exit(1)
    }
    cd := exec.Command("cd", folderPath)
    config := exec.Command("./configure", "--disable-yasm")
    build := exec.Command("make")

    cd_err := cd.Start()
    if cd_err != nil {
        log.Fatal(cd_err)
    }
    log.Printf("Waiting for command to finish...")
    cd_err = cd.Wait()
    log.Printf("Command finished with error: %v", cd_err)

    start_err := config.Start()
    if start_err != nil {
        log.Fatal(start_err)
    }
    log.Printf("Waiting for command to finish...")
    start_err = config.Wait()
    log.Printf("Command finished with error: %v", start_err)

    build_err := build.Start()
    if build_err != nil {
        log.Fatal(build_err)
    }
    log.Printf("Waiting for command to finish...")
    build_err = build.Wait()
    log.Printf("Command finished with error: %v", build_err)

}

func folderExists(path string) (bool, error) {
    _, err := os.Stat(path)
    if err == nil {
        return true, nil
    }
    if os.IsNotExist(err) {
        return false, nil
    }
    return true, err
}

我想要命令，就像从终端一样。 cd path; ./configure; make
因此，我需要依次运行每个命令，并等待最后一个命令完成后再继续。在当前版本的代码中，当前./configure: no such file or directory假设是因为执行cd path并在新的shell中执行了./configure，而不是与上一个命令位于同一目录中。有任何想法吗？
更新 我通过更改工作目录然后执行./configure和make命令解决了该问题

err = os.Chdir(folderPath)
    if err != nil {
        fmt.Println("File Path Could not be changed")
        os.Exit(1)
    }

现在我还是很好奇，是否有办法在同一个外壳中执行命令。
