The Linux mkdir command is used to create a directory of the specified name, requiring the user who created the directory to have write permissions in the current directory, and the specified directory name cannot be a directory that is already in the current directory.


1. Command format:

mkdir [Options] directory ...


2. Command function:

The mkdir command enables you to create a folder or directory that is named DirName (the specified file name) at the specified location. The user who creates the folder or directory must have write permissions to the parent folder of the folder that is created. Also, the folder (directory) You create cannot have the same name as the filename in its parent directory (that is, the parent folder), that is, the same directory cannot have the same name (case sensitive).

In a Linux system, the function of command mkdir is to create a new folder.


Mkdir-p can create a new subdirectory in the new subdirectory.

Example:

Mkdir-p About/abc/def can create a new three directory at a recursive level.


If you want to see what mkdir has done, you can add the option "-V" to continue with the example above:

Copy the code code as follows:

MKDIR-PV About/abc/def

mkdir:created directory ' about '

mkdir:created directory ' ABOUT/ABC '

mkdir:created directory ' About/abc/def '
