What does the 'mkdir' command do?

The 'mkdir' command is a basic Unix/Linux command used to create a new directory. When this command is executed, it generates a directory with the specified name within the current working directory, or in a specified location. This functionality is crucial for organizing files and directories within a file system, allowing users to create a structured environment for their documents and applications.

For example, if a user wants to create a directory called "Projects," they would simply run the command mkdir Projects. Following this command, a new directory named "Projects" would be created in the current location, enabling the user to store related files conceptually within that directory. Understanding this command is fundamental for Linux file management and is a foundational building block for users interacting with the Linux operating system.
