How to find all hard links in a directory on Linux

You can use the find command to find all hard links in a directory on Linux. A hard link is a second reference to an existing file that has the same inode number as the original file.

Here’s the command to find all hard links in the current directory and its subdirectories:

Explanation:

• . is the current directory. You can replace it with the desired directory path.
• -type f only searches for files.
• -links +1 matches files that have more than one hard link, i.e., the files that are linked more than once.

This will list all the hard-linked files in the specified directory and its subdirectories.
