Symbolic links, or symlinks, are one of Linux’s most useful filesystem features. They allow you to create shortcuts to files or directories across your system without duplicating the original data. This is particularly handy for organizing files, redirecting software paths, or managing shared resources more flexibly.
There are two common types of links in Linux:
- Soft links (symbolic links): Think of these like shortcuts or aliases.
- Hard links: These reference the actual data on the disk at the inode level.
In this guide, we’ll focus on creating symlinks using the command line and understanding the difference between soft and hard links.
Create a Symbolic Link Using the "ln" Command
The ln command is the standard utility in Linux to create both hard and soft links. To create a symbolic link, you must use the -s flag (short for-- symbolic).
Syntax:
# ln -s <target_path> <link_name>
<target_path> – This is the original file or folder you want to link to.
<link_name> – This is the name/location of the symbolic link you're creating.
Example:
Let’s say you want to create a symbolic link on your desktop that points to a "Backup" directory in your home folder:
# sudo ln -s /home/user/Backup /home/user/Desktop/backups
This will create a link named backups on your desktop that points to the /home/user/Backup directory. When accessed, it behaves just like the original folder.
Checking Existing Symlinks
To verify if a symbolic link exists and where it points, use the ls -l command:
# ls -l /home/user/Desktop/backups
Expected output:
lrwxrwxrwx 1 user user 16 Jul 21 10:30 backups -> /home/user/Backup
The l at the beginning indicates it’s a symlink, and the arrow (->) shows the target.
Conclusion:
Creating symbolic links in Linux is a clean and efficient way to manage file structure, redirect paths, or simplify repetitive operations. Whether you're building deployment environments, automating workflows, or just organizing your directories better, symlinks offer flexibility without redundancy.
Use soft links for most cases, especially for directories and across different file systems. Avoid hard links unless you have a very specific need and fully understand the implications.
