Detailed explanation of Linux file system architecture
Linux is an open source operating system, and its file system architecture plays a vital role. The file system is an important part of the operating system responsible for managing data. There are many different file systems in the Linux system, and each file system has its specific advantages and uses. In this article, we will analyze the architecture of the Linux file system in detail, from the basic concepts of the file system, directory structure to specific code examples, to help readers better understand and apply the Linux file system.
A file system is a method used by the operating system to organize and manage data. Its core goal is to store and access files on disks or other storage devices. In the Linux system, the file system is responsible for arranging files to storage locations on the disk and providing file access and management interfaces. Linux systems support many different types of file systems, including common ext4, XFS, NTFS, etc.
The directory structure of Linux file system starts from the root directory "/", and all files and directories are expanded from the root directory. Some common important directories include:
Linux file system mainly consists of the following parts:
Below we use specific code examples to show the file system operations so that readers can better understand:
View file system information
sudo df -Th
This command is used to view information about all file systems in the current system, including file system type, total size, used size, etc.
Mount a new file system
sudo mount /dev/sdb1 /mnt/new_fs
This command will The /dev/sdb1 partition is mounted to the /mnt/new_fs directory so that the new file system can be accessed.
##Create a new file
touch /mnt/new_fs/new_file.txtI hope this article can bring readers an understanding and application of the Linux file system, and further improve system management and development capabilities.
