inode number

First get to know the ln and update-alternatvies commands.LN LinkFirst, let's talk about the Linux link, which is divided into two kinds: symbolic link (symbolic link) and hard link (hard link).We know that files have file names and data, which are

File attributes (Ls-lhi see the information)1.1 First column: Inode number 1.1.1 What is inodeThe file is stored on the hard disk, and the minimum storage unit for the hard disk is called "Sector" (sector). The size of each "sector" is 512 bytes

The main partitioning mechanism has MBR and GPT two MBR partitions: The first sector is the most important, with the following: The boot code (Bootstrap codes area) and the partition table (partition table), where Bootstrap code area occupies 446

Understanding Linux Inode? ?1. Origin and role of the Inode 2. What content is contained in the Inode table 3. How the file system reads file 4 through the inode. A special type of existence: Hard link 5. Structure of the catalog file? ?1

Here is the basics of storage management for Linux, using a new hard drive device step (partition, format, mount Partition).First, Linux storage Management basic knowledge point1. Hardware compositionIn the computer basic knowledge, each hardware is

Divided into two parts: memory and process.Memory1) Check memory and memory allocation for several commands:A) Nmon: graphical interface, not only to look at the memory, but also to see the CPU, network, kernel, disk information, memory can see Swap,

The philosophy of Linux one is that everything is file, and everything in Linux exists in the form of files. It is difficult to find and deal with so many files. Therefore, some commands are needed to locate and locate files.File lookup: Search for

File lookup: Search for files by filename or file property;A) LocateFuzzy Lookup:Based on a dedicated database to find, the database should be created in advance, and regularly updated;You can manually update the locate database using the UpdateDB

One: the generation and development of Linux1. In 1946 the University of Pennsylvania produced the first computer Eniarc. Operation 5,000 times per second but still defective. First, the user exclusive whole machine, resource utilization is low.

Source: Linux Community PvbutlerFirst, the question:When creating a file in the/data partition of a Linux server, the system prompts for insufficient disk space, uses the df-h command to view the disk usage, finds that the/data partition uses only 66

A glimpse of Linux distinguishes hard connection from soft connection. I. Two Connection Files and creation methods in Linux. There are two Connection Files in Linux: soft connection and hard connection, although they are all connected files, there

First look at block (concept of block), block is the smallest unit of file access, usually 8 sectors is a block, and each sector size is 512 bytes is 0.5K, so the size of a block is 8*0.5k=4k.The system uses Inode to identify filesYou can use the

Hard Link features :Because a hard link is a file with the same inode number with only a different file name, there are several characteristics of hard links:1. The file has the same inode and DataBlock2. Only files that already exist can be created3

There are two types of Connection Files in Linux: one is a file similar to the shortcut function of windows, which allows us to quickly connect to the target file, called symbolic link ); the other is to generate a new file name through the inode
