Directories

Context

Work with directories using os.Mkdir, os.MkdirAll, os.ReadDir, os.Remove, and os.RemoveAll.

Example

Create a directory, list its contents, then remove it.

Code example

package main

import (
    "fmt"
    "os"
)

func main() {
    err := os.Mkdir("testdir", 0755)
    if err != nil {
        fmt.Println("Error creating dir:", err)
        return
    }
    defer os.RemoveAll("testdir")

    entries, err := os.ReadDir(".")
    if err != nil {
        fmt.Println("Error reading dir:", err)
        return
    }
    for _, e := range entries {
        fmt.Println(e.Name(), e.IsDir())
    }
}

Output (example)

testdir true
main.go false
