mkdir directory_name ...

The user must have write permission in the parent directory.

• Create a directory:
  

  $ mkdir folder

  
  
• Create multiple directories and optionally their sub-directories:
  

  $ mkdir folder folder/folder1 folder/folder2

  
  
• You can use the option -p to create a sub-directory and its parents if they don't exist:
  

  $ mkdir -p folder/folder2

  
  
• Create a directory with a specific permission:
  

  $ mkdir -m 777 folder

The following options can be used:

-m <mode>
|Set the file permission mode of the created directory.
|The mode argument can be in any of the formats specified by the chmod command.
|If a symbolic mode is specified, the operation characters "+" and "-" are interpreted relative to an initial mode of "a=rwx".

-p
|Create intermediate directories as required.
|If this option is not specified, the full path prefix of each operand must already exist.
|On the other hand, with this option specified, no error will be reported if a directory given as an operand already exists.
|Intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permission for the owner.

-v
|Cause mkdir to be verbose, showing files as they are created.
