删除目录和所有子目录

Question

这是我尝试过的：package mainimport (    "fmt"    "os/exec")func main() {    fmt.Println("Removing build directory")    if err := exec.Command("cmd", "/S /Q", "RD", "c:\\build").Run(); err != nil {        fmt.Printf("Error removing build directory: %s\n", err)    }    if err := exec.Command("cmd", "/C", "mkdir", "c:\\build").Run(); err != nil {        fmt.Printf("Error making new build directory: %s\n", err)    }}我的输出是：Removing build directoryError making new build directory: exit status 1所以删除时我没有收到任何错误，但它不会删除任何内容。这是为什么 ？

试试这个..

func main() {

    fmt.Println("Removing build directory")

   c := exec.Command("cmd", "/C", "rd /S /Q", "C:\\build")

    if err := c.Run(); err != nil { 

        fmt.Println("Error: ", err)

    }  

    if err := exec.Command("cmd", "/C", "mkdir", "c:\\build").Run(); err != nil {

        fmt.Printf("Error making new build directory: %s\n", err)

    }

}
