Create a listing in Go (Golang)

To create a single listing in Go, use the os.Mkdir() perform. If you wish to create a hierarchy of folders (nested directories), use os.MkdirAll(). Each features require a path and permission bits of the folder as arguments.

Within the examples beneath, we use the os.ModePerm fixed as permission bits which is equal to 0777. For directories in Unix-like programs, it signifies that a person has rights to checklist, modify and search recordsdata within the listing.

Create a single listing

package deal foremost

import (
    "log"
    "os"
)

func foremost() {
    if err := os.Mkdir("a", os.ModePerm); err != nil {
        log.Deadly(err)
    }
}

The os.Mkdir() creates a brand new listing with the desired identify, however can not create subdirectories. For instance, if you happen to use os.Mkdir() with "a/b/c/d" as a identify argument:

os.Mkdir("a/b/c/d", os.ModePerm)

you get the error:

mkdir a/b/c/d: no such file or listing

Create a hierarchy of directories (nested directories)

package deal foremost

import (
    "log"
    "os"
)

func foremost() {
    if err := os.MkdirAll("a/b/c/d", os.ModePerm); err != nil {
        log.Deadly(err)
    }
}

The os.MkdirAll() creates a given listing, together with any mandatory guardian folder. Use this perform if it is advisable create a nested hierarchy of directories in your program.
