The mkdir command is used Create a directory. This command creates a directory named by dirname. If no pathname is added in front of the directory name, the directory specified by dirname will be created in the current directory; if an existing path is given, a specified directory will be created in that directory. When creating a directory, make sure that the newly created directory does not have the same name as the file in the directory where it is located.

Note:

When creating files, do not store all files in the main directory. You can create subdirectories to organize files more effectively. . It's best to use consistent naming to distinguish files and directories. For example, a directory name can start with an uppercase letter so that it appears first in directory listings.

A subdirectory should contain files of similar type or purpose. For example, you might create a subdirectory that contains all your database files, another subdirectory that contains your spreadsheet files, another subdirectory that contains your word processing documents, and so on. Directories are also files. They follow the same naming rules as ordinary files, and a directory can be uniquely specified using the full path.
