A brief analysis of Linux directory structure

Linux inherits the distinct features of the UNIX operating system structure. The file structure under Linux is very organized. However, the above advantages can only be realized when you are quite familiar with Linux. Now, the worm will simply introduce the directory structure under Linux.

We already know that every Linux has a kernel (vmlinuz), and we add modules to this kernel that can do a variety of specific functions, each of which is embodied in various directories in Linux. Of course, different distribution packages have small differences in their catalogs, but the main structure is the same. We'll also combine the Linux functional modules with a variety of applications, so that your Linux system can serve you. The kernel of the system is stored in the/vmlinuz directory. Remember when we configured Lilo to mention the kernel?

Obviously, bin is the binary (binary) abbreviation. In the general system, you can find the common Linux commands in this directory. In some versions you will also find some directories in the same directory as the root directory.

In this directory is stored in the system to be used to start the program. When we use Lilo to boot Linux, we use some of the information here.

DEV is the acronym for Devices. This directory is important to all users. Because this directory contains all the external devices used in the Linux system. But this is not the driver for the external device. This is not the same as our usual Windows, DOS operating system. It is actually a port that accesses these external devices. We can easily access these external devices, and access a file without any difference in a directory. For example: We type in the system: Cd/dev/cdrom we can see the files in the CD-ROM. Similarly, we type: Cd/dev/mouse can look at the mouse related files. In this directory, there is a null device, and the thing itself has no meaning. If you write files or content to this directory, they all have no return.

This directory is empty when you just installed the system. You can attach the optical drive file system to this directory. Example: Mount/dev/cdrom/cdrom

Etc This directory is one of the most important directories in the Linux system. This directory contains the various configuration files and subdirectories to be used in system administration. We need to use the network configuration files, file system, x system configuration files, device configuration information, set up user information, etc. are in this directory. Later, the worm will also explain in detail the contents of this directory.

This directory is used to store system administrator's system management program.

If we set up a user, the user name is "XX", then in the/home directory there is a corresponding/home/xx path, used to store the user's main directory.

LIB is the English abbreviation of library. This directory is used to store the system dynamic connection shared library. Almost all applications use shared libraries in this directory. Therefore, do not easily do anything to this directory, once the problem occurs, your system will not work, then you don't say bug didn't remind you ah.

This directory is empty in most cases. But if you are working suddenly with a power outage, or you are not shutting down normally, some files will not be available when you restart the machine, and for these files, the system places them in this directory, as if providing a temporary shelter for homeless people.

This directory is also empty under normal circumstances. You can temporarily hang other file systems in this directory.

System information can be obtained in this directory. This information is in memory and generated by the system itself.

If you are logged in as a superuser, this is the Superuser's home directory.

Used to store temporary files that are generated when different programs are executed.

This is the largest directory in the Linux system that occupies hard disk space. Many of the users ' applications and files are stored in this directory.
