由于文件权限问题,RemoveAll()不应工作

关键是对包含文件的目录拥有写权限,如本例所示

package main

import (
        "fmt"
        "os"
)

func dostuff(p os.FileMode, n string) {

        err := os.Mkdir(n, 0700) // make as writable
        _, err = os.Create(n + "/a")
        _, err = os.Create(n + "/b")

        os.Chmod(n, p) // alter permissions to see what happens
        err = os.RemoveAll(n)
        if err != nil {
                fmt.Println("cannot delete the file", err)
        }

}

func main() {
        dostuff(0700, "writeallowed")
        dostuff(0400, "readonly")
}
