Soft link and hard link details Today, we will introduce the following soft links and hard links. I. What is inode? To understand inode, start with file storage. 1. The file is stored on the hard disk. The minimum storage unit of the hard disk is 51

The hard link records the inode of the target, and the soft link records the path of the target. Soft links are like shortcuts, while soft links are like backups. Soft links can be used as cross-partition links, while hard links can only be used as
