Linux System main directory function

/BIN: is the acronym for Binary, which is a legacy of UNIX system habits, storing the commands most often used by users. such as: Ls,cp,cat and so on.

/boot: Here are some of the core files used to start Linux.

/dev: is the abbreviation of device. This directory is the external device of any Linux, with functions similar to the. SYS and the. vxd under Win in DOS. Devices and documents 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 any configuration documents and subdirectories required for system administration.

/home: Use the head of household directory, for example, a user called Sina, then his main directory is/home/sina, said here to make a fork. You should now understand that before we visit some personal pages. such as: Http://www.sina.com/sina, Sina is to access the site of users Sina user home directory. If the website's operating system is Linux, that means/home/sina.

/lib: This directory holds the most basic dynamic link shared library of the system, which acts like a. dll document in Windows. Almost any application needs to use these shared libraries.

/lost+found: This directory is usually empty, and when the system shuts down, it becomes a refuge for homeless documents. Somewhat similar to the. chk document under DOS.

/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, it is the mapping of system memory, we can access this directory directly to obtain system information. The contents of this directory are not on the hard drive but in memory.

/root: System administrator, also called root user directory.

/sbin:s is the meaning of super user, which means that there are systems management programs used by system administrators.

/tmp: This directory, needless to say, must be a place to store some temporary documents.

/var: There are things that are constantly expanding in this directory, and in order to maintain the relative stability of/usr, directories that are often modified can be placed in this directory, and in fact many system administrators do. The system's log document is in the/var/log directory.

/usr: expansion of the base directory, many directories are the same as the root directory. Most of the applications we use are stored in this directory. In specific terms:

/USR/X11R6: A directory for storing x-windows.

/usr/bin: There are many applications stored.

/usr/sbin: Here are some of the management programs that are used for superuser (root).

/usr/doc: This is the base of the Linux documentation.

/usr/include:linux the header document needed to develop and compile the application is found here.

/usr/lib: Store Some commonly used dynamic link shared libraries and static archives.

/usr/local: This is the/USR directory provided to the general user, where the software is best suited for installation.

/usr/man: is the Help document directory.

/usr/src:linux Open Source Code, there is this directory.

Some Linux defaults are not installed source code, need to manually install. Installation method Another article introduced: http://blog.csdn.net/wangyuling1234567890/article/details/21344571
