Why can’t you create a hard link to a directory?
We cannot create a hard link for a directory to avoid recursive loops. If original file is removed then the link will still show the content of the file.

How do I allow a hard link to a directory in Linux?

Why are hard-linking directories not allowed in Linux?

How many hardlinks can a directory have without a child?
So here we can understand that hardlinks are there for directories only to connect with their parent and child directories. And so a directory without a child will only have 2 hardlink, and so directory “b” will have only two hardlink.
How do I create a hard link in Linux?
A hard link can be easily created with the help of a built-in command ln available in almost all major UNIX and Linux distributions like Ubuntu, Kali, Parrot, Linux mint, etc. I already created a sample file with name file.txt.
What are soft and hard links in Unix/Linux?
Soft and Hard links in Unix/Linux. 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.
