How to Create Directories in Linux Using the mkdir Command

Introduction

The mkdir command enables the creation of directories in a file system. It's also known as make directory (mkdir) and allows you to create directories and sub-directories to organize the file system structure.

This article explains how to use the mkdir command in Linux to create and manage directories.

mkdir Command Syntax

Below is the basic mkdir command syntax:

$ mkdir [options] directory_name...

Within the above command, [options] includes optional flags that modify the command behavior, and directory_name... specifies the name of the directory to create. You can center multiple names separated by a comma , to create multiple directories simultaneously.
