Linux file Management

The philosophical thinking of LINUX: all documents;

Normal file

Catalog files

Link file

Device files

Pipeline files

Directory:

/file system's upper root directory

/bin Store user-Frequently used commands, such as Ls,cat

The files that are required when the/boot operating system starts

/dev Interface device files such as/DEV/SDA represent the first physical SATA interface hard disk

/etc to store the configuration files and subdirectories required for system management

Home Directory for general users

File system mount points for/media devices

/proc is a virtual directory, is the system memory mapping, can obtain system information

/root Root User's home directory

/sbin the program to be executed when the system is started

/tmp deposit some temporary files

/USR Stores system commands and application information used by the user

/lib Storage System The most basic dynamic link sharing library

/lost+found usually empty, when not properly shut down, here to store the recovered files

var store variable nature of the relevant program directory

mkdir: New Directory

MkDir Linux represents the creation in the current directory

[[email protected] ~]# mkdir Linux
