Which command is used to create a new directory?

The command used to create a new directory in Linux is "mkdir". This stands for "make directory". When executed, it allows users to specify a name for the new directory they wish to create. This command is fundamental in file system management, enabling users to organize their files into categorized folders or directories.

Other commands listed, such as "newdir", "createdir", and "makefolder", do not exist as standard commands in Linux for directory creation. Therefore, understanding the proper command is essential for effective navigation and organization within the Linux environment.
