Golang - 执行shell脚本，实时输出shell脚本中的日志： 

package mainimport ("bufio""fmt""io""os/exec""strings"
)func SafetyShell(execName string, arg ...string) (string, error) {ex := exec.Command(execName, arg...)result, err := ex.CombinedOutput()if err != nil {return "", err}return strings.TrimSpace(string(result)), nil
}func execSH() bool {execSH := []string{"./exec.sh"}res, err := SafetyShell("/bin/sh", execSH...)fmt.Println(fmt.Sprintf("res: %+v", res))fmt.Println(fmt.Sprintf("err: %+v", err))if err != nil {return false}return true
}func executeShellScript(execName string, arg ...string) error {cmd := exec.Command(execName, arg...)stdout, err := cmd.StdoutPipe()if err != nil {return err}stderr, err := cmd.StderrPipe()if err != nil {return err}if err := cmd.Start(); err != nil {return err}go func() {reader := bufio.NewReader(stderr)for {line, err := reader.ReadString('\n')if err != nil || io.EOF == err {break}fmt.Print(line)}}()reader := bufio.NewReader(stdout)for {line, err := reader.ReadString('\n')if err != nil || io.EOF == err {break}fmt.Print(line)}if err := cmd.Wait(); err != nil {return err}return nil
}func main() {//flag := execSH()//fmt.Println("flag : ", flag)// 可以实时输出shell脚本中的echo输出，和错误输出execSH := []string{"./exec.sh"}err := executeShellScript("/bin/sh", execSH...)if err != nil {fmt.Println("Error:", err)}}
