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).
3. Command parameters:
-M,--mode= mode, set permissions < mode > (similar to chmod) instead of rwxrwxrwx minus Umask
-P,--parents can be a path name. In this case, if some directories in the path do not already exist, and with this option, the system will automatically establish those that do not already exist, that is, multiple directories can be established at one time;
-V,--verbose displays information each time a new directory is created
--HELP Display this help message and exit
--version output version information and exit

Add:
This command creates the specified directory name, requires 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
Grammar:
mkdir [-M] [-p] Directory name
Option Description:
-M: Set access permissions on the new directory or set with the chmod command;
-P: Can be a path name. In this case, if some directories in the path do not already exist, and with this option, the system will automatically establish those that do not already exist, that is, multiple directories can be established at one time;
Example of execution:
Copy the code code as follows:
$ mkdir Dira
$ ls
Dira </p> <p> $ mkdir-m 775 DIRB
$ ls-l
Drwxr-xr-x 2 xxxx users 4096 Feb 22:29 Dira
Drwxrwxr-x 2 xxxx users 4096 Feb 22:30 DIRB </p> <p> $ mkdir-p Dirc/hello
$ ls-l
Drwxr-xr-x 2 xxxx users 4096 Feb 22:29 Dira
Drwxrwxr-x 2 xxxx users 4096 Feb 22:30 DIRB
Drwxr-xr-x 3 xxxx users 4096 Feb 22:31 dirc </p> <p> $ ls dirc
Hello
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 '
