At digiwallet, we understand the importance of efficiency and organization within your Linux system.

One very powerful tool that can significantly enhance your workflow is the symbolic link, often referred to as a symlink.

How to use symbolic links in Linux (and why you should)

Symlinks function similarly to shortcuts on Windows, providing a way to access files or directories from convenient locations without physically storing the data itself.

This blog delves into the world of symbolic links in Linux, exploring their creation, usage, and the numerous benefits they offer.

Understanding Symbolic Links

Imagine a scenario where your favorite music collection resides on a separate partition for storage purposes.

While you can navigate to that specific partition each time you want to play music, wouldn’t it be easier to have a quick access point within your home directory?

This is precisely where symbolic links come in. A symlink acts as a special file containing the path to the actual target file or directory.

When you interact with the symlink, the system seamlessly redirects you to the target location, providing a transparent user experience.

It’s crucial to differentiate between symbolic links and hard links, another type of Linux link.

Whereas a symbolic link points to the target’s location, a hard link creates a duplicate entry for the same file, essentially acting as another doorway to the original data.

This distinction becomes important when considering how changes to the target file affect the links themselves.

Modifications made to the target file will be reflected in both the symlink and any hard links pointing to it.

However, since a symlink only stores a reference, changes made to the symlink itself won’t affect the target.

Creating Symbolic Links: The ln Command

The ln command serves as your gateway to creating symbolic links in Linux. It offers various functionalities, but for symlinks, we’ll focus on the -s flag, which designates the creation of a symbolic link. The basic syntax follows this structure:

ln -s <target_path> <link_name>
  • <target_path> represents the complete path to the existing file or directory you want to link to.
  • <link_name> signifies the name you wish to assign to the symbolic link.

Here’s a practical example: Let’s say your music collection resides at /media/storage/music. You can create a symlink named MyMusic within your home directory using the following command:

ln -s /media/storage/music ~/MyMusic

Once executed, you’ll have a symlink named MyMusic in your home directory, which acts as a convenient access point to your music collection.

Specifying Relative Paths and Target Directories

The usefulness of symbolic links extends beyond just linking files.

You can also create symlinks that point to directories. The syntax remains similar, but the target path should specify the directory location.

Additionally, symlinks can leverage relative paths, offering more flexibility in how you structure your links.

For instance, imagine you have a project directory within your home directory (~/projects) and frequently use a specific subfolder named data (~/projects/data).

You can create a symlink named project_data on your desktop that points to this subfolder using a relative path:

ln -s ../projects/data ~/Desktop/project_data

This approach keeps your desktop organized while providing easy access to the frequently used subfolder.

Advantages of Symbolic Links

Now that you possess the knowledge to create symbolic links, let’s explore the compelling reasons to integrate them into your Linux workflow:

  • Enhanced Organization: Symlinks empower you to organize your files logically, regardless of their physical location. This promotes a cleaner and more streamlined file system structure, especially when dealing with data stored on separate partitions.
  • Flexibility and Customization: Symlinks grant you the freedom to arrange access points for frequently used files or directories in convenient locations within your user space. This customization fosters a more efficient workflow.
  • Simplified Application Configuration: Certain applications in Linux rely on configuration files residing in specific directories. Symbolic links enable you to keep these configuration files in a centralized location while maintaining functionality for the application, even if it expects the configuration file to be in a different directory.
  • Future-Proofing: If you anticipate moving your data to a different location in the future, symlinks provide a layer of insulation. You can simply update the target path within the symlink, ensuring applications and users continue to access the data seamlessly without needing to modify file paths throughout the system.

Best Practices for Effective Symlink Usage

While symbolic links offer numerous advantages, it’s essential to be mindful of certain aspects:

  • Broken Links: Since symlinks rely on the existence of the target file or directory, a change in the target location can lead to broken links. These become inoperable shortcuts and can clutter your file system if not addressed. Regularly checking for broken links and updating them accordingly is crucial for maintaining a clean and functional environment. The ls -l command can help identify broken symlinks, indicated by a missing target path.
  • Understanding Permissions: The permissions associated with the target file or directory will also apply to the symlink itself. Ensure that the user or process utilizing the symlink has the necessary permissions to access the target location.
  • Relative vs. Absolute Paths: While relative paths offer flexibility, they can introduce challenges if you move the symlink itself. Absolute paths provide a more permanent solution but may require adjustments if the target location changes. Consider your specific use case when deciding between relative and absolute paths.
  • Judicious Use: While symlinks are powerful tools, avoid creating an excessive number of them. An overly complex network of symlinks can obscure the true location of your data and hinder maintainability. Use symlinks strategically to enhance organization and workflow efficiency.

Unlinking and Following Symlinks

Once you’ve created symlinks, there may come a time when they’re no longer necessary. The unlink command allows you to remove symlinks. The syntax is straightforward:

unlink <link_name>

This command removes the specified symlink but doesn’t affect the target file or directory itself.

Understanding where a symlink points can be helpful for troubleshooting or managing your file system. The readlink command discloses the target path associated with a symlink:

readlink <link_name>

This command provides the complete path to the target file or directory that the symlink references.


Symbolic links enables you to go through your Linux file system with efficiency and organization, understanding their creation process, advantages, and best practices, you can use symlinks to streamline your workflow and maintain a well-structured system.

So, next time you find yourself browsing a complex file system hierarchy, consider utilizing symbolic links to create convenient access points and enhance your Linux experience.

This blog post has equipped you with the knowledge to create and manage symbolic links effectively.
