How to remove all contents of a directory using Golang?

Question

I\'m new to Go and can\'t seem to find a way to delete all the contents of a directory when I don\'t know the contents.

I\'ve tried:

os.RemoveAll(\"/tmp/         


        

Answer 1

Just use ioutil.ReadDir to get a slice of os.FileInfo types, then iterate through and remove each child item using os.RemoveAll.

package main

import (
    "io/ioutil"
    "os"
    "path"
)

func main() {
    dir, err := ioutil.ReadDir("/tmp")
    for _, d := range dir {
        os.RemoveAll(path.Join([]string{"tmp", d.Name()}...))
    }
}

That way, you are removing only all the child items and not the parent /tmp folder itself.

I have used this pattern many times before (e.g. test logs, etc.).
