What is the purpose of `mkdir -p`?

The mkdir -p command is used to create directories in a Linux environment. Its purpose includes:

1. Create Parent Directories: It allows the creation of nested directories in a single command. If any parent directory does not exist, it will be created automatically.

2. No Error for Existing Directories: If the specified directory already exists, using -p prevents an error message from being displayed.

For example, mkdir -p new-dir/subdir will create both new-dir and subdir if they do not exist, without raising an error if they already do.
