A deep dive into how Linux file systems are organized

Title: An in-depth look at how the Linux file system is organized

In a Linux system, the file system is a key part of storing, organizing, and managing data. Understanding how Linux file systems are organized is crucial for system administrators and developers. This article will delve into the organization of the Linux file system, including its directory structure, characteristics and basic operations, and provide specific code examples for demonstration.

1. Directory structure of Linux file system

The Linux file system adopts a tree structure, also known as a hierarchical file system. The root directory is the starting point of the entire file system, and all files and directories start from the root directory. Common directories include:

• /: Root directory
• /bin: Stores system executable commands
• /etc: Stores system configuration files
• /home: Home directory of ordinary users
• /usr: Stores software installed by users
• /var: Stores changed files, such as log files
• /tmp: Temporary files Storage directory

2. Characteristics of Linux file system

A notable feature of Linux file system is that “everything is a file”, that is, everything can be represented by a file. Including hard disks, drives, devices, etc. all exist in the form of files. In addition, the Linux file system supports multiple types of file systems, such as ext4, XFS, and Btrfs, etc. Each file system has its specific advantages and uses.

3. Basic operation examples of Linux file system

3.1. View file system information

df -h

The above command can view the entire file system Usage, including disk space usage, etc.

3.2. Create directory

mkdir test_directory

The above command will create a new directory named "test_directory" in the current directory.

3.3. Move the file

mv file1.txt /tmp

The above command will move the file "file1.txt" to the /tmp directory.

3.4. Copy file

cp file1.txt file2.txt

The above command will copy the file "file1.txt" to "file2.txt".

3.5. Delete file

rm file1.txt

The above command will delete the file "file1.txt".

Conclusion

Through the introduction of this article, we have an in-depth discussion of the organization of the Linux file system, including the directory structure, characteristics and basic operations. A deeper understanding of the Linux file system will help you better manage and operate the file system. Hopefully the code examples provided in this article can help readers better understand how Linux file systems are organized.
