Directory Structure of Linux

Linux directory structure detailed

/bin: Binary available to all users;

/sbin: Binary files for system administration use;

/boot: Each static file that the bootloader must use: Kernel, Initramfs (INITRD), grub, etc.;

/dev: Store special files or device files;

There are two types of devices: Character devices (linear devices), block devices (random devices);

/etc: The configuration file of the System program; (contains shell scripts for starting/stopping a single process)

/home: The central location of the general family directory; The home directory of each ordinary user is the default subdirectory with the same name as the user name in this directory,/home/username;

/root: Administrator's home directory; optional;

/lib: Provides a shared library for system startup or applications on the root file system (/bin,/sbin, etc.) and provides kernel modules for the kernel

Libc.so.*: Dynamically linked C library;

ld*: Runtime linker/loader;

Modules: The directory used to store kernel modules;

/LIB64:64-bit system-specific path for storing 64-bit shared libraries;

/media: Portable equipment mount point, CDROM, floppy, etc.;

/MNT: Temporary mount point for other file systems;

/OPT: Installation location of the additional application, optional path;

/SRV: Data provided by the current host for the service;

/tmp: Temporary files, including system and user-created temporary files, the file will be deleted in the directory when the system restarts.

/USR:USR Hierarchy, globally shared read-only data path;

Bin, Sbin

LIB, lib64

INCLUDE:C program header file;

Share: Storage location of schema-specific files such as command-book pages and self-documenting documents

Local: another level directory;

Installation location of the X11r6:x-window program

SRC: Where the program source files are stored

/usr/local:local hierarchy, which allows the system administrator to install local applications, and is typically used to install third-party programs;

/var:/var Hierarchy, a directory that stores data that is often changed;

CacheApplication cache data

LibVariable state information

LocalVariable data for/usr/local

LockLock files

Loglog files and directories

OptVariable data for/opt

RunData relevant to running processes

SpoolApplication Spool Data

TMPTemporary files preserved between system reboots

/PROC: Process information; Contains information about system processes and system resources that exist in text form

/SYS:SYSFS virtual file system provides a better way to access kernel data than proc; its main function is to provide a unified model interface for managing Linux devices;
