what inode

Each process has a task_struct struct in the Linux kernel to maintain process-related information, known as process descriptor. In operating system theory, it is called a process control block (PCB, process control block ). Task_struct has a pointer

1.ls-lhiText Explanation:First column: Inode index node number (person's ID, national only)When the system reads the file, it first finds the inode through the filename before it can read the file contents.Second column: File type and permissions (a

Note the following:1) each time a process opens a file, a file structure corresponds to it. The same process can open the same file multiple times to obtain multiple different file structures. The file structure describes the attributes of the

1, struct inode── character device driver related important structure introductionThe kernel uses the inode structure to represent the specific file, and the file structure represents the open descriptor. In the Linux2.6.27 kernel, the inode

1. Inode and Block overviewAfter the partition of each Linux storage device or storage device is formatted (EXT3,EXT4, etc.), there are usually two parts: the Inode, and the other part is the block. Block is used to store the actual data, and the

When partitioning and formatting partitions, the entire partition is divided into two parts, the Inode and data block (where the actual data is placed in the data region), which is the unique identifier (directory, archive) file in a file system.

What is an inodeIn the unix/linux system, on the surface, the user opens the file by file name, in fact, the system inside this process is divided into three steps: First, the system to find the file name corresponding to the inode number, and

Let's start with the formatting: The file attributes/permissions set by each operating system are not the same, and in order to store the data needed for these files, you need to format the partition to be a file system format that the operating

to say the inode, you have to start from the physical format of the hard disk, the minimum storage unit of the hard disk is the sector, that is, sector, each sector storage 512 bytes. and the general file system will have its own minimum reading and

1. Initial knowledge of the Inode:The file is stored on the hard disk (the minimum storage unit of the hard disk is "sector" (sector), 512 bytes per sector)When the operating system reads the hard disk, it reads a block (8 sector) at once.The

OneThe inode is a data structure in a file system on a Unix-like system. Data is stored on disk as a sector, and several sectors form a block, and the operating system reads the data on the disk efficiently, by block. The address of the block where

mentioned above: one of the most important tasks of Linux system administrators is to manage their own disk file systems, each partition is not too large or too small, too much to cause the disk capacity wasted, too small will cause the resulting
