what is INODE in linux
1. Inode is a data structure on a traditional unix-style file system such as UFS. An inode stores all the information about a regular file, directory, and file system expect its data and name.
2. A file system relies on data structures that contain information about files, beside the file content. The former is called metadata (data which describe data).
3. Each file is associated with an inode, which is identified by an integer number, often referred to as i-number or i-node.
4. Inodes store information about files and folders, such as ownership, access mode (read, write, execute permission) and filetype.
5. A file inode No. can be found using the " ls -i " (for inode no. of file).
