INODE

 Inode:

1. An inode is an index node.

2. An Inode number is a uniquely existing number for all the files in Linux and unix like systems.

3. When a file is created on a system, a file name and Inode number is assigned to it.

4. Inode doesn't contain the file name. Reason for this is to maintain hard-links for the files.

Inode Contents

An Inode is a data structure containing metadata about the files.

Following contents are stored in the Inode from a file:

  • User ID of file
  • Group ID of file
  • Device ID
  • File size
  • Date of creation
  • Permission
  • Owner of the file
  • File protection flag
  • Link counter to determine number of hard links
Note: The Inode doesn't contain file content, instead it has a pointer to that data.
