How to find all hard links in a directory on Linux

To find all hard links in a directory on Linux, you can use the find command with the -type and -links options. The syntax is as follows:

find /path/to/directory -type f -links +1

Replace /path/to/directory with the path of the directory you want to search.

This will search the specified directory and all of its subdirectories for files that have more than one hard link. The -type f option tells find to search for files, and the -links +1 option tells it to search for files with more than one hard link.

You can use the -print option to print the paths of the found files:

find /path/to/directory -type f -links +1 -print

You can also use the -ls option to list the found files in a long format:

find /path/to/directory -type f -links +1 -ls

Keep in mind that hard links are multiple directory entries that refer to the same file on a file system. A file with multiple hard links will have more than one name, but it is still a single file with a single inode.

If you want to find all files in a directory, regardless of whether they have hard links or not, you can omit the -links +1 option:

find /path/to/directory -type f

This will search the specified directory and all of its subdirectories for all files.
