What is mkdir command?

• The mkdir command is is used to create new directories.

• A directory, referred to as a folder in some operating systems, appears to the user as a container for other directories and files. However, Unix-like operating systems treat directories as merely a special type of file that contains a list of file names and their corresponding inode numbers. Each inode number refers to an inode, which is located in inode tables (which are kept at strategic locations around the filesystem) and which contains all information about a file (e.g., size, permissions and date of creation) except its name and the actual data that the file contains.
