在同一shell golang中运行多个Exec命令

  • command-line
  • shell
  • exec

I'm having trouble figuring out how to run multiple commands using the os/exec package. I've trolled the net and stackoverflow and haven't found anything that works for me case. Here's my source:

package main

import (
    _ "bufio"
    _ "bytes"
    _ "errors"

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

    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)
    cd := exec.Command("cd", folderPath)
    config := exec.Command("./configure", "--disable-yasm")
    build := exec.Command("make")

    cd_err := cd.Start()
    if cd_err != nil {
    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.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.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

I want to the command like I would from terminal. cd path; ./configure; make So I need run each command in order and wait for the last command to finish before moving on. With my current version of the code it currently says that ./configure: no such file or directory I assume that is because cd path executes and in a new shell ./configure executes, instead of being in the same directory from the previous command. Any ideas? UPDATE I solved the issue by changing the working directory and then executing the ./configure and make command

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

Still now i'm curious to know if there is a way to execute commands in the same shell.
