刪除目錄及其所有子目錄

Question

這是我的嘗試：

package main 

import (
    "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) 
    } 
} 

而且我的輸出是：

Removing build directory 
Error making new build directory: exit status 1 

所以我沒有得到消除，當任何錯誤，但它不會刪除任何東西。

這是爲什麼？

試試這個..

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) 
    } 

}
