This may save only a few keystrokes, but if you find yourself making a lot of symbolic links this could add up significantly. Note: Because symbolic links are typically used more frequently than hard links, some may find it beneficial to alias ln to ln -s: To ensure that youвЂ™re creating symbolic links, you can pass the -s or -symbolic option to the ln command. For instance, you should avoid using hard links when linking inside of a git repository as they can cause confusion.

Hard links serve their purpose in the world, but they should be avoided entirely in some cases. If you delete the original file, though, the hard link will still work, and you can view and edit it as you would a normal copy of the original file. Like symbolic links, if you edit the contents of the original file those changes will be reflected in the hard link. If you delete the original file, the link will be broken as it no longer has anything to point to.ДЄ hard link is instead a mirror copy of an original file with the exact same contents. If you make a symbolic link to that file, the link is only a pointer to the original file. Understanding Hard LinksД«y default, the ln command will make hard links instead of symbolic, or soft, links. With these sample documents in place, youвЂ™re ready to practice making symbolic links.

On Ubuntu, for example, you can install it with apt: Note: If tree isnвЂ™t installed on your machine by default, you can install it using your systemвЂ™s package manager. If you were to run tree at this point to display the contents of the entire /tmp/symlinks directory and any nested subdirectories, its output would look like this: Similarly, this command creates a file named two.txt within the two/ subdirectory whose only contents are a single line reading two: The following command creates a file named one.txt within the one/ subdirectory whose only contents are a single line reading one: Navigate into the new symlinks/ directory:ДЇrom there, create a couple sample files, one for both of the subdirectories within symlinks/.

It creates a directory named symlinks/ within the /tmp/ directory, and two directories (one named one/ and another named two/) within symlinks/: The following mkdir command creates three directories at once. This will be useful for the purposes of this guide, since you can create as many directories, files, and links as youвЂ™d like without having to worry about them clogging up your system later on. tmp/ is a temporary directory, meaning that any files and directories within it will be deleted the next time the server boots up. YouвЂ™re welcome to use existing files on your system to practice making symbolic links, but this section provides a few commands that will set up a practice environment you can use to follow along with this guideвЂ™s examples.Д«egin by creating a couple directories within the /tmp/ directory. The command weвЂ™ll be using to create the links is the ln command. The system call necessary to create symbolic links tends to be readily available on Unix-like and POSIX-compliant operating systems. Click the following Launch an Interactive Terminal! button to open a terminal window and begin working with a Linux (Ubuntu) environment. Doing so will set you up with a secure server environment - including a non- root user with sudo privileges and a firewall configured with UFW - which you can use to build your Linux skills.ДЄlternatively, you can use an interactive terminal embedded on this page to experiment with the sample commands in this tutorial. If you plan to use a remote server to follow this guide, we encourage you to first complete our Initial Server Setup guide. Note that this tutorial was validated using a Linux server running Ubuntu 20.04, but the examples given should work on a computer running any version of any Linux distribution. This can either be a virtual private server which youвЂ™ve connected to with SSH or your local machine. To follow along with this guide, you will need access to a computer running a Linux-based operating system.

This guide provides an overview of what symbolic links are and how to to create them from a Linux command line using the ln command. Think of them like wormholes for your file system.

However, when you interact with them, they will actually interact with the target at the other end. From the userвЂ™s perspective, symbolic links are very similar to normal files and directories. They go by many names including symlinks, shell links, soft links, shortcuts, and aliases. Symbolic links allow you to link files and directories to other files and directories.
