How do you create a link in Unix?

By default, the ln command creates hard links. To create a symbolic link, use the -s ( –symbolic ) option. If both the FILE and LINK are given, ln will create a link from the file specified as the first argument ( FILE ) to the file specified as the second argument ( LINK ).

Replace source_file with the name of the existing file for which you want to create the symbolic link (this file can be any existing file or directory across the file systems). Replace myfile with the name of the symbolic link. The ln command then creates the symbolic link.

To create a symbolic link pass the -s option to the ln command followed by the target file and the name of link. In the following example a file is symlinked into the bin folder. In the following example a mounted external drive is symlinked into a home directory.

To make links between files you need to use ln command. A symbolic link (also known as a soft link or symlink) consists of a special type of file that serves as a reference to another file or directory.

A link in UNIX is a pointer to a file. Like pointers in any programming languages, links in UNIX are pointers pointing to a file or a directory. Creating links is a kind of shortcuts to access a file. Links allow more than one file name to refer to the same file, elsewhere.

A hard link is essentially a label or name assigned to a file. This new link is not a separate copy of the old file, but rather a different name for exactly the same file contents as the old file. … Consequently, any changes you make to oldfile will be visible in newlink .

If a hard link is created for a text file. Then the original text file is deleted, then basically a copy of that file’s name is created, in a sense that original file gets deleted.

To view the symbolic links in a directory:

  1. Open a terminal and move to that directory.
  2. Type the command: ls -la. This shall long list all the files in the directory even if they are hidden.
  3. The files that start with l are your symbolic link files.

The reason hard-linking directories is not allowed is a little technical. Essentially, they break the file-system structure. You should generally not use hard links anyway. Symbolic links allow most of the same functionality without causing problems (e.g ln -s target link ).

Soft links are similar to shortcuts, and can point to another file or directory in any file system. Hard links are also shortcuts for files and folders, but a hard link cannot be created for a folder or file in a different file system. Let’s look at the steps involved in creating and removing a symlink.
