• mkdir - Make directory.

  username@linux:~$ mkdir newfolder
  username@linux:~$ ls
  newfolder

• mkdir -p - The -p or --parents flag, adds some powerful functionality to this command in creating multiple levels of directories by creating all parent directories that do not exist.

  username@linux:~$ mkdir -p way/to/new/directory

  If way, way/to, or way/to/new do not exist, mkdir -p will create them automatically, ensuring that the final directory way/to/new/directory exists.

  username@linux:~$ mkdir -p /home/user/project/{src,bin,docs}
  username@linux:~$ cd /home/user/project
  username@linux:~/home/user/project$ ls
  bin  docs  src

  This command would create a project directory under /home/user, and within project, it would create src, bin, and docs directories, all in one go, without throwing an error if any of these directories already exist.
