Like pointers in any programming languages, links in UNIX are pointers Basically hard link increases reference count of a location while soft links work as a.
A hard link is essentially a label or name assigned to a file. Furthermore, hard links cannot refer to files located on different computers linked by NFS, nor can they refer to directories. For all of these reasons, you should consider using a symbolic link, also known as a soft.
Before getting into the term Symbolic link and Hard link,lets understand the term ' inode'. A Unix file is “stored” in two different parts of the disk.
A hard link is merely an additional name for an existing file on Linux or other Unix -like operating systems. Any number of hard links, and thus.
In computing, a hard link is a directory entry that associates a name with a file on a file system. as all Unix-like systems, additional hard links to existing files are created with the link() system call, or the ln and link command-line utilities.
The main advantage of hard links is that, compared to soft links, there is no size or speed penalty. Soft links are an extra layer of indirection on.
To understand how Unix hard links and link counts work, it helps to understand how Every directory or file on Unix has its storage managed by its own inode.
