TL;DR
To create a directory in Linux using mkdir command, you can try these methods:
- To create a single directory, use the command
mkdir documentsin the terminal. - For creating multiple directories at once, run
mkdir photos videos documents. - To create nested directories, use the
-poption withmkdir -p parent/child.

Keeping your files organized on Linux can make a big difference, just like using folders for documents, pictures, or music on your computer. The mkdir command in Linux is your go-to tool for this. In this post, I’ll show you how to use mkdir to create single and multiple directories, set permissions, and even add timestamps. You’ll also learn how to avoid common mistakes that can trip you up. By the end, you’ll have a solid grasp of managing directories efficiently and effectively.
What is the mkdir Command?
The mkdir command in Linux stands for make directory. It lets you create new directories (folders) on your file system. Think of it as a way to organize your files into different categories, just like creating folders on your computer to store documents, pictures, or music.
Importance in Unix-Based Systems
- Organization: Helps users and administrators organize files neatly.
- Efficiency: Saves time by quickly creating directories through simple commands.
- Structure: Provides a clear, hierarchical structure for data storage.
- Automation: Can be used in scripts to automate directory creation tasks.
- Consistency: Ensures consistent directory structures across different systems and users.
- Management: Facilitates easier management and navigation of the file system.
- Security: Allows setting permissions and ownerships, enhancing file system security.
Basic Syntax of mkdir
The basic syntax to create a directory in Linux using mkdir command is:

mkdir: The command itself.[OPTION]: Optional flags that change how the command works. These are not always needed.DIRECTORY: The name of the directory or directories you want to create.
How to Create a Directory in Linux Using mkdir Command
To create new directories using mkdir command in Linux, you have several powerful methods at your disposal. From creating single directories to managing nested directories and setting specific permissions, the mkdir command provides flexible options for organizing your files and folders. Additionally, you can incorporate timestamps into directory names for better version control.
1. Single Directories
Creating a single directory using the mkdir command is a straightforward method that allows you to quickly organize your files and folders with meaningful names, making it easier to locate and manage specific content. To create a directory in Linux using mkdir command, follow these steps:
- Open the Terminal.
- Enter the following command to create a directory named documents:
mkdir documents- Press Enter to execute the command.
2. Multiple Directories
The ability to create multiple directories simultaneously with the mkdir command saves time and effort, making it ideal for situations where you need to create several related directories at once, such as setting up project folders or organizing different categories of files. To create directories in Linux, follow these steps:
- Launch the Terminal window and enter the mkdir command, followed by the names of the directories separated by spaces. For example, to create directories named photos, videos, and documents, use the following command:
mkdir photos videos documents- The command will create multiple directories at the same time.
3. Nested Directories
The capability to create nested directories or subdirectories using the mkdir command enables you to establish a hierarchical structure for your files, providing a systematic organization that simplifies navigation and enhances overall file management. Follow these steps to create nested directories:
- Access the command window.
- Specify the parent directories along with the child directory names, separated by slashes (/). For example, to create a directory structure with a parent directory named parent and a child directory named child, use the following command:
mkdir -p parent/child- The command will create a hierarchical structure of the directories.
4. Directories with Different Permissions
By utilizing the mkdir command to create directories with specific permissions, you can ensure the security and integrity of your files, granting appropriate access levels to different users or groups, thus maintaining control over your directory structure. To set specific permissions while creating directories, follow these steps:
- Enter your command window.
- Enter the mkdir command, followed by the directory name and the desired permissions. For example, to create a directory named private with read and write permissions, use the following command:
mkdir -m 600 private- The output will be:
5. Directories with Timestamps
Incorporating timestamps into directory names using the mkdir command helps you track file changes and assists in version control, providing valuable information about the creation or modification times of files, allowing for better organization and historical references.Follow these steps to create directories with timestamps:
- Luanch the Terminal window and run the mkdir command, followed by the desired directory name, along with the timestamp. For example, to create a directory named backup_20230607, use the following command:
mkdir backup_20230607- Press Enter to execute the command to create directory with Timestamps.
Common Mistakes to Avoid and Tips to Prevent Errors
Creating directories with the mkdir command is simple, but small mistakes can cause issues. Here are five common mistakes to avoid and tips to help you prevent errors.
- ✏️ Misspelling Directory Names: Typing errors can lead to unexpected directory names or errors. Double-check your directory names before running the command to avoid these issues.
- ⚙️ Forgetting the -p Option: Not using the -p option prevents mkdir from creating nested directories if the parent directories don’t exist. Always include the -p option when creating nested directories.
- 🔒 Using Incorrect Permissions: Incorrect permissions can make directories inaccessible or insecure. Use the -m option to set appropriate permissions when creating directories.
- 📂 Creating Duplicate Directories: Running the mkdir command with an existing directory name can cause errors or confusion. Check if a directory with the same name already exists to avoid duplication.
- 🔍 Ignoring Case Sensitivity: Linux is case-sensitive, so Documents and documents are different directories. Be mindful of case sensitivity and be consistent with your naming conventions.

Frequently Asked Questions
Is it possible to create directories with special characters using mkdir?
How can I create directories with a specific owner or group using mkdir command?
chown and chgrp commands. To change the owner of a directory, use the command chown followed by the desired user and the directory name. For example, chown john my_directory would change the owner of my_directory to the user john. To change the group, use the command chgrp followed by the desired group and the directory name. For example, chgrp staff my_directory would change the group of my_directory to staff.What is the maximum length limit for directory names created with mkdir?
Can the mkdir command be used to create directories on remote servers?
ssh user@remote_server mkdir remote_directory would create a directory named remote_directory on the remote server. Ensure that you have the necessary permissions and access rights to create directories on the remote server before attempting to use the mkdir command remotely.
