linux-(1) Linux tree file system structure and the role of each folder

The Linux file system is an inverted single tree structure.

The root of the file system is "/"

Everything in Linux is a file.

As shown in the following:

The functions of each folder are as follows:

Bin: Holds executable files that can be executed by all users.

Boot: Store system boot, start related content. The vmlinux is the kernel file.

Dev: The file that holds the hardware device. Because everything in Linux is a file, the hardware is also abstracted into files.

ETC: This directory holds operating system-related configuration files

Home: An ordinary user's home directory. Each user has a private directory in this directory (in addition to the root user)

LIB: Repository file

Lost+found:ext folder for file system

Media: Automatically mount a directory, such as a USB flash drive. But not all Linux has this directory.

MNT: Manually mounted devices typically use this directory

Opt: A directory that installs large software, such as Oracle

Proc: This directory contains real-time information about the operating system. Does not exist on the hard disk and only exists in memory

Root:root User's home directory

Sbin: Executable file (different from bin directory) that can only be executed by superuser (root)

SYS: hardware information at the bottom of the system

TMP: Temp directory, the contents of which will be automatically deleted by the system.

USR: This directory is typically used to install application software

var: This directory user holds frequently changing information, such as logs.
