inode number

Hard links on soft and hard links in LinuxHard link, if file B is a hard link to file A, the inode number of a is the same as the inode number of B, that is, an inode node corresponds to two different file names, two file names point to the same

In Linux, everything is file. Each file has an inode number that matches it, and each inode can match multiple files.and links have soft links, hard links of the points. A soft link is like a shortcut to Windows, and a hard link is like an alias

First, the Linux file access processThe root directory in the Linux system is self-referencing, for example, to find/etc/sysconfig/networkscripts/ifcfg-0 filesFirst locate the storage/disk block in the Inode table based on the root directory/inode

First, the meaning of disk partitioningDisk partitioning is to divide the disk into different logical regions, each of which can have different file systemsTwoThe disk partition is partitioned according to the disk's cylinder, because the disc

     What is a . inode ? (index node)              Understanding inode  need to know the file storage, the file is stored on the hard disk , when the operating system reads the hard disk, it reads multiple sectors (the smallest storage unit of the

We know that Linux has a mind "everything is a file (including hardware)", this is a basic document management experienceFile system structure elementsFile system and directory structureFeatures of Linux files: File names are case sensitive

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

If you find that the created symbolic link cannot be deleted, you can only find that the file name cannot be suffixed with one/after the symbolic link is deleted /. For example:[WHB @ jcwkyl test] $ ln-S ~ WHB[WHB @ jcwkyl test] $ lsWHB[WHB @ jcwkyl

We know that the disk needs to be formatted after partitioning, before the operating system can use this partition. The reason for formatting is that the file attributes/permissions set by each operating system are different. In Linux, the
