mkdir -p dir_name1/dir_name2/dir_name3

Flag "p" stands for parent . This flag which enables the command to create parent directories as necessary.(It means , command is use to create parent directories preferably .)

This command is used to create sub-directories in a parent directory. Here, the dir_name1 is the parent directory inside it dir_name2 sub-directory is created and similarly dir_name3 is created inside the dir_name2.
This command is for creating multiple directories but with a hierarchy of parent and child and sub-child. If the directory is already created , while executing this command it will not show any error. It will execute successfully.

syntax : mkdir -p parent_dir/child_dir/sub-child_dir

In figure.4 shows that mangalore is parent_dir, udupi is child-dir and manipal is sub-child dir .

mkdir -p dir1 dir2/dir3

By using this command can create multiple directories with hierarchy of two parent directories are created and one child directory for second parent and so on.
