Linux System directory function description

/bin:bin is the abbreviation for binary (binary). This directory is a lineage of Unix system habits, with commands that users use most often. For example: Cp,ls,cat.
&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP; Boot: Here are some of the core files used to start Linux.

/dev:dev is an abbreviation for device (device). This directory is the external device for all Linux, with functions similar to the. SYS and WIN under DOS. Devices and files are accessed in Linux in the same way. For example:/dev/hda represents the first physical IDE hard disk.
ETC: This directory is used to store all the configuration files and subdirectories required for system administration.
FileSystem: The user's home directory, such as a user named Liubin, then his home directory is/home/liubin can also be used ~liubin said, here, a fork, you should now understand that in our visit to some personal pages (such as http:// Www.liubin.net/~liubin), ~liubin is the user's home directory that represents access to the user Liubin in the www.liubin.net site.
If the operating system of this website is Linux, it means/home/liubin.
Lib: This directory holds the most basic dynamic link shared library of the system, which acts like a. dll file in Windows. Almost all applications need to use these shared libraries.
/lost+found: This directory is usually empty, and when the system shuts down, it becomes a refuge for homeless files. Yes, something similar to the DOS. chk file.
MNT: This directory is empty and the system provides this directory to allow users to temporarily mount other file systems.
/proc: This directory is a virtual directory, which is the mapping of system memory, we can access this directory directly to obtain system information. In other words, the contents of this directory is not on the hard disk but in memory Ah!?
/root: System administrator, also known as the user home directory for super privileges. Of course, the owner of the system, there must be some privileges Ah!
/sbin:s is the meaning of super user, which means that there are system management programs used by system administrators.
/tmp: This directory, needless to say, must be a place to store some temporary files.
/usr: This is the largest directory, and many of the applications and files we use are stored almost in this directory. Specifically:

/USR/X11R6 Storage X-windows Directory;
/usr/bin stores many applications;
Sbin Some of the management programs that are used by the super users.
/usr/doc This is the base of Linux documentation;
/usr/include Linux to develop and compile applications needed for the header file, find it here;
/usr/lib store some commonly used dynamic link shared libraries and static archives;
Usr this is provided to the general user's/usr directory, where the installation software is most suitable;
What/usr/man man is, is help. This is the Help document directory!
/USR/SRC Linux Open Source code, there is this directory, enthusiasts do not let go Oh!

var: there are things that are constantly expanding in this directory, in order to maintain the relative stability of/usr, the frequently modified directories can be placed in this directory, in fact many system administrators do this. Incidentally, the system log files are in the Var directory.

The most common directories are listed here, and the directory structure varies according to the Linux release suite. and the catalogue you built yourself, of course I don't know what to save. Hopefully, the above text will allow you to leave a panorama of Linux in your brain so that you can get a thorough understanding of all the other aspects of Linux.
