英文:
Remove directory and all subdirectories
问题
这是我尝试的代码：
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)
}
}
我的输出是：
Removing build directory
Error making new build directory: exit status 1
所以在删除时我没有收到任何错误，但它没有删除任何内容。
为什么会这样？
英文:
This is what I tried:
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)
}
}
And my output is:
Removing build directory
Error making new build directory: exit status 1
So I don't get any error when removing, but it doesn't delete anything.
Why is that ?

试试这个..
func main() {
fmt.Println("删除构建目录")
c := exec.Command("cmd", "/C", "rd /S /Q", "C:\\build")
if err := c.Run(); err != nil {
fmt.Println("错误: ", err)
}
if err := exec.Command("cmd", "/C", "mkdir", "c:\\build").Run(); err != nil {
fmt.Printf("创建新的构建目录时出错: %s\n", err)
}
}
英文:
Try this..
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)
}
}
