Learn how to create symlink in Linux, also known as Symbolic Links!
Symlinks, also referred to as symbolic links, are a great feature on Linux. They let you make shortcuts or links to files and folders, making it simpler to access them from different places. Symlinks act as pointers to the original file or folder, making navigation through your system smoother.
ln command with the correct options, you can create a symlink in Linux. You need to specify the original file or folder you want to link and set a name for the symlink. The symlink gets its own unique path, but points to the location of the original file or folder.
One cool thing about symlinks is they can go across different filesystems. This means you can make a symlink in one spot that points to a file or folder in another spot, even if they exist on different storage drives. This makes symlinks a helpful tool for managing and organizing your files in Linux.
It’s worth noting that while symlinks do provide convenience and flexibility, they have potential risks. If you delete a symlink, it only wipes out the reference and not the real file or folder it points to. So, if you delete a symlink by mistake, you won’t lose the original file or folder. However, if you delete the original file or folder, the symlink will be damaged and it won’t serve its purpose.
How to create a symlink in Linux
Creating a symlink in Linux involves creating a symbolic link between files or directories. The symlink acts as a reference or shortcut to the original file or directory. Here’s a step-by-step guide on how to create a symlink in Linux:
- Open the terminal: Open the command-line interface in Linux.
- Navigate to the desired directory: Use the “cd” command to navigate to the directory where you want to create the symlink.
- Create the symlink: Use the “ln -s” command followed by the original file or directory path and the desired name and location for the symlink. For example, to create a symlink called “symlink” to the file “original_file.txt” located in the “/path/to/file” directory, you would type:
ln -s /path/to/file/original_file.txt symlink
Once you’ve followed these steps, the symlink will be created in the specified location. You can then access the original file or directory using the symlink.
It’s important to note that symlinks can be useful for various purposes, such as creating shortcuts to frequently accessed files or organizing directories. They provide flexibility and convenience in managing files and directories in a Linux system.
1. Understanding the concept of symlinks
Symlinks, also known as symbolic links, are a cool feature of the Linux OS. They let you create a special type of file that works like a shortcut or reference to another file/directory. It’s like a signpost pointing to the actual location.
An advantage of using symlinks is that they make it easy to access files/directories without having to remember their exact locations.
For example, you have a folder called “Documents” in a deep part of your filesystem.
Instead of navigating there, you can make a symlink on your desktop. This symlink looks and behaves like any other file/directory. When you open it, you go to the original “Documents” folder.
Symlinks are powerful because they work across different partitions or even different filesystems. You can make a symlink in one spot that points to a file/directory in another spot. That offers convenience when organizing/accessing your files.
It’s interesting that symlinks have been around since the early days of Unix systems. They were created for efficient disk space and easier management of files/directories. Today, symlinks are an important part of Linux and are used by both new and experienced users.
2. Creating a symbolic link using the ln command
- Open your Linux system’s terminal.
- Navigate to the directory you want to put the symbolic link.
- Then use this command: ln -s /path/to/original /path/to/link.
- Replace “/path/to/original” with the exact path of the file or directory you’re linking.
- Also, replace “/path/to/link” with the place and name of the symbolic link.
Making symlinks is useful. It gives easy access to important files and folders while keeping your file structure organized. Plus, it’s a core feature of Linux. That makes file and folder management easier.
Key considerations when creating symlinks in Linux
Creating symlinks in Linux requires certain considerations to ensure proper functionality and compatibility. Here’s a step-by-step guide to help you create symlinks effectively:
- Determine the source and target locations: Identify the file or directory you want to link (source) and the location where the link should point to (target).
- Verify permissions: Ensure that you have sufficient permissions to create symlinks in the target location. Use the ‘ls -l’ command to check the permissions of both the source and target directories.
- Choose the appropriate symlink type: Decide whether you want to create a soft or hard symlink. Soft symlinks (symbolic links) are references to the target’s file name and can span different file systems, while hard symlinks are direct pointers to the target’s location.
- Create the symlink: Use the ‘ln’ command followed by the appropriate options. For example, to create a soft symlink named ‘link’ pointing to ‘target’, you can use the command ‘ln -s target link’. To create a hard symlink, omit the ‘-s’ option.
- Test the symlink: Verify the functionality of the symlink by accessing it and confirming that it correctly points to the target location. Ensure that any software or scripts relying on the symlink are working as expected.
It is important to note that when creating symlinks in Linux, you should avoid naming conflicts and ensure the target file or directory exists. Additionally, be cautious when moving or deleting the source or target, as it can affect the functionality of the symlink.
1. Ensuring proper file permissions and ownership
To make sure you set the right file permissions and ownership when creating symlinks, follow these 6 steps!
- Identify the target file. This is the file or directory you want to link to.
- Check current permissions. Use “ls -l” to view the target’s user, group, and access rights.
- Assign ownership. Use “chown” to choose the owner and group.
- Set permissions. Use “chmod” with numerical values or symbols for read (r), write (w), and execute (x).
- Create symlink. Use “ln” with “-s” to make the link.
- Verify creation. Use “ls -l” again to check your link points to the correct target.
It’s important to not grant too many privileges. Else, potential security breaches, data loss, and system instability may occur. Take control now!
2. Handling relative and absolute paths in symlinks
When it comes to managing relative and absolute paths in symlinks, there are a few things to keep in mind. Understanding the differences and utilizing the right strategies can guarantee smooth functioning. Let’s take a look at how these paths work:
This type of path is relative to the current working directory. It does not start with a leading slash (/) or drive letter (e.g., C:/). It only specifies the location of a file/directory based on its relationship to your position in the file system.
This one is the opposite. It gives the full location of a file/directory from the root of the file system. It includes drive letters (if applicable) and intermediate directories.
Now, here’s how to handle relative and absolute paths properly:
- Use relative paths when referencing files in the same directory or subdirectories. This creates more flexible symlinks, and it’s transferable across systems. It also avoids reliance on absolute locations.
- Use absolute paths for essential system files/directories. This ensures stability and prevents issues caused by changes in working directories or symbolic link targets.
- Consider environment variables. This enables dynamic referencing based on variable values. It gives a more adaptable solution.
To conclude, managing relative and absolute paths in symlinks needs careful thinking. Choosing the right path types, using relative paths when possible, and incorporating environment variables when needed, can optimize your symlinks’ functionality and resilience.

To delete it, use the
rm command with the symlink’s name.
Check if an entry is a symlink via the
-L option with
ls -L link-to-file.
To edit/delete multiple symlinks, use wildcards (*) with
rm. For instance:
Be cautious when updating/deleting symlinks– double-check names & locations. Additionally, create backups of important files/directories before making any changes. That way, if anything goes wrong, data can be recovered. Follow these guidelines to manage your system’s file structure while minimizing potential risks & complications. Stay organized & attentive to ensure a smooth Linux environment.
3. Handling broken symlinks
Identify broken symlink by ‘ls’ command. Remove or rename with ‘rm’ or ‘mv’. Create new symlink with ‘ln’. Automatically detect & remove broken symlinks with ‘find’ & ‘xargs’. Regularly check symlink integrity to avoid issues.
In addition, reflect on broken symlink impact on system functioning & performance. Ignoring may result in erroneous data access & unexpected app behavior.

Conclusion: Create Symbolic Links in Linux
Creating a symlink in Linux is easy. Use the ln command to link two files or directories. This offers flexibility and convenience.
It is important to understand the difference between absolute and relative paths. Absolute paths show a file or directory’s exact location in the file system hierarchy. Relative paths show the location relative to the current working directory.
To create a symlink, open the terminal and go to the desired location. Then, use the ln command with the -s option. Specify the target file or directory you want to link to. After that, give the symlink a name and path.
For example, let’s say you have a “folder1” with “file1.txt”. You want to make a symlink named “symlink1” in “folder2”. Navigate to “folder2” and use this command:
ln -s ../folder1/file1.txt symlink1
This makes “symlink1” in “folder2” which points to “file1.txt” in “folder1”.
If you move or delete the original file or directory, the symlink will still be there but won’t function correctly.
Remember: Make sure you have permissions for both the original file or directory and the location for the symlink. Symlinks can make your life easier by providing quick access to files and directories.
