What is Inode in Linux?
An inode is a data structure that keeps track of all the files and directories within a Linux filesystem
Linux File system is based on Inode Entries
Inode holds the metadata about the files
It contains Owner of the file/size of the file/UID/GID/Timestamp
==============================
What is Hard link in Linux?
An Hard link is just a different name for the same file
One file can have many different names or hard links
Inode holds the metadata about the files
Syntax:
ln {target file} {src file}
=============================
What is soft link in Linux?
A Soft link is similar to windows shortcut
One file can have many shortcuts pointing to it
It will main different Inode number
If you delete the original file,softlink shortcut will not work

Syntax:
ln –s {target file} {src file}

Linux inode include:

Inode: A data structure in a Unix-style file system that describes a filesystem object such as a file or directory.

Filesystem: A method used to control how data is stored and retrieved on a storage device.

Metadata: Data that provides information about other data, such as file size, permissions, and creation date.

Disk allocation: The process of assigning space on a storage device to files and directories.

Data blocks: The portions of a storage device where the actual content of files is stored.

Filesystem hierarchy: The organization of files and directories into a tree-like structure.

File permissions: Settings that determine who can read, write, or execute a file.

Hard link: A reference to an inode that allows multiple filenames to point to the same data on disk.

Soft link (symbolic link): A special type of file that points to another file or directory by name.

Filesystem consistency: Ensuring that the data and metadata stored on a filesystem remain coherent and correct.
