An inode is a data structure in the Unix-style file system. It describes a file system object such as a file or a directory. Whenever a file is created in Unix, a set amount of inodes will also be created. A file in Unix system is given a unique number and this unique number is called as an inode. Each file and directory have an inode value. By using this inode number, the file information such as user, group, ownership, and access mode information can be found.
