/bin binary Executable command

/dev Device Special files

/etc system administration and configuration files

/ETC/RC.D startup configuration files and scripts

The base point of the home user directory, such as the user's home directory is/home/user, can be represented by ~user

/lib Standard Programming Library, also known as dynamic Link shared library, acts like a. dll file in Windows

/sbin System Management commands, which are stored in the hypervisor used by the system administrator

/tmp Common temporary file storage point

/root system Administrator's home directory (hehe, privileged Class)

The/MNT system provides this directory to allow users to temporarily mount other file systems.

/lost+found This directory is usually empty, the system is not properly shut down and leave the "homeless" files (what is called under Windows. chk) right here.

/proc a virtual directory, which is a mapping of system memory. This directory can be accessed directly to obtain system information.

/var overflow area for some large files, such as log files for various services

/usr The largest directory, the applications and files to be used almost all in this directory. These include:

/USR/X11R6 the directory where x window is stored

/usr/bin a multitude of applications

/usr/sbin Some management programs for super users

/usr/doc Linux Documentation

/usr/include the header files needed to develop and compile applications under Linux

/usr/lib Common dynamic-link libraries and package profiles

/usr/man Help Documentation

/USR/SRC source code, the Linux kernel source is placed in the/usr/src/linux

/usr/local/bin Local Add-on command

/usr/local/lib locally added Coogan file system

Typically, the root filesystem occupies a smaller space because most of the files do not need to be changed frequently, and include strict files and a small, infrequently changed file system that cannot be easily damaged.

In addition to a possible system boot image called/V m L-N U-Z standard, the root directory generally does not contain any files.
All other files are in subdirectories of the root file system.
