What is difference between symbolic link and hard link?
Symbolic links link to a path name. This can be anywhere in a system’s file tree, and doesn’t even have to exist when the link is created. The target path can be relative or absolute. Hard links are additional pointers to an inode, meaning they can exist only on the same volume as the target.
What is hard link and symbolic link in Unix?
A hard link is a file that points to the same underlying inode, as another file. In case you delete one file, it removes one link to the underlying inode. Whereas a symbolic link (also known as soft link) is a link to another filename in the filesystem.

Should I use hard link or soft link?
Hard links are more forgiving when you delete a file; soft links take up less data, but soft links don’t store the actual data, or the location of the original file. Both types of links have their own quarks and uses. Creating them from the command line is easy.
What happens when you create a hard link?
-In file systems when there is more than one link for the same file, hard links are associated with such files. 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.
How do I find a symbolic link?
To view the symbolic links in a directory:
- Open a terminal and move to that directory.
- Type the command: ls -la. This shall long list all the files in the directory even if they are hidden.
- The files that start with l are your symbolic link files.
