One Linux command per day (3) mkdir command

The mkdir command is used to create the directory. This command creates a directory named by DirName.     If no pathname is added before the directory name, the directory specified by DirName is created under the current directory, and if an existing path is given, a specified directory will be created under that directory. When creating a directory, make sure that the new directory does not have the same name as the file in the directory it is in.

(1) Usage:    

mkdir [Options] ... Directory...

(2) function:

Create a directory if the specified directory does not exist

(3) Option parameters

1)-Z: Set security context, valid when SELinux is used

2)-m:< target properties > or-mode< Target properties > Set directory permissions while setting up the directory

3)-P or--parents if the top-level directory to be set up is not currently established, the upper-level directory will be created

4)-version display version information
