In UNIX systems, everything except processes is a file, which is maintained by Linux. To facilitate file management, Linux also introduces the concept of directories (sometimes called folders. Directory enables file classification and management,
Inode, hard link, and soft link methods for Linux File storage, and inode for file storageFile Storage
Files are stored on hard disks,Slice(Sector) is the smallest physical storage unit in the disk. Generally, the size of each slice is 512 bytes,
Links and differences between hard links and soft links
We know that files have filenames and data, which are divided into two parts on Linux:metadata (metadata) is an attached property of a file, such as file size, creation time, owner, and so
First, what is the inode?To understand the inode, start with the file storage. The file is stored on the hard disk, and the minimum storage unit for the hard disk is called "Sector" (Sector). Each sector is stored 512 bytes (equivalent to 0.5KB).
Linux The difference between a soft link and a hard linklinux linux The above is divided into two parts: metadata and data. User data, which is the file data block ( data block linux inode # ( inode is part of the file's metadata, but it does not
The difference between hard links and soft links in Linux1. In principle:Hard link:A is a hard link to B (both A and b are filenames), the Inode node number in A's directory entry is the same as the Inode node number in the directory entry for B,
In a Linux system, there are two kinds of links: one is called hard link (hardlink), the other is called symbolic link or soft link (symbolic).1 ) How to create :a ) By default without parameters, LN The command creates a hard link, and the ln
Linux hard link and soft link, linux Link
In a Linux File System, disk blocks are divided into three parts. A part is called a data zone and used to store the file content. Another part is called inode table, which is used to store file attributes.
There are two ways to file links in Linux, one is hard link, also referred to as rigid links, the other is symbolic link, also known as symbolic link. To differentiate between the two, review the common Linux ext2 file system. This filesystem uses
Today, I see a very interesting question on the understanding:How to evaluate Microsoft senior Engineer obsessed with soft link this common concept of Linux?Although it is well-known tearing forced the king has a certain tear force, but I still want
The operation of the file system is related to the operating system's archival data, the newer operating system's archival data, in addition to the actual contents of the file, usually contains a lot of attributes, such as the Linux operating system
A few days ago, a company's project required recursive File Retrieval. Due to my temporary negligence, I did not consider the existence of Connection Files, as a result, the released program may fall into the major bug of an endless loop, without
0X00 What is a linked file
The linked file in Linux is the equivalent of a shortcut in Windows, which can be accessed by linking files to the source files that the link points to. However, there is a certain difference between the link file under
Linuxsystemfiles in the file are file names and data in theLinuxthe above is divided into two parts: metadata and data. User data, which is the file data block (Data Block), the data block is where the real content of the file is recorded, and the
Hard Link LN:The Unix file system provides a mechanism for linking different files to the same file, called links. It allows a single program to use different names for the same file. The benefit is that the file system only has a copy of the file.

Symbolic Link: deleting a symbolic link will delete the file;
Hard link: deleting a hard link will not delete the file, but will only reduce the link Count value by one.
What is the difference between symbolic link and hard link?

(1) Hard linksIn general, the file name and inode number are the "one by one correspondence" relationship, and each inode number corresponds to a file name. However, the Unix/linux system allows multiple filenames to point to the same inode number.
