Linux directory structure naming convention
Almost all Linux versions will follow FHS (Filesystem Hierarchy Standard), Chinese translation is the filesystem hierarchy standard. C similar to the Windows operating system disk file directory, FHS organize files using a tree structure. FHS defines the purpose of each region of the system, files and directories that constitute the minimum required, but also gives the exception process with the conflict processing.
Linux Directory Structure
/ Boot: the boot file storage directory, kernel file (vmlinuz), the boot loader (bootloader, grub) are stored in this directory;
/ Bin: basic commands for all users to use; can not be associated to a separate partition, OS startup program that is will be used;
/ Sbin: basic commands management classes; not related to a separate partition, OS started, is used procedure;
/ Lib: Basic shared libraries and kernel module files (/ lib / modules);
/ Lib64: dedicated auxiliary x86_64 shared library file system on the storage position;
/ Etc: Configuration Files directory (plain text files);
/ Home / USERNAME: regular user's home directory;
/ Root: administrator's home directory;
/ Media: a portable mobile device mount point;
/ Cdrom: CD-ROM mount point
/ Usb: USB device mount point
/ Mnt: Temporary file system mount point;
/ Dev: special device file and a file storage location;
b: block device, random access
