What function does the Type command serve in a command line interface?

The Type command serves the specific function of displaying the contents of a text file in a command line interface. When executed, it reads the file specified by the user and outputs its contents to the screen. This allows users to quickly view and verify the text or data within a file without needing to open a separate text editor.

The other functions listed in the choices do not apply to the Type command. Executing a program involves a different command that runs executable files, while compiling source code requires a specific compiler command to convert source files into executable formats. Creating a new directory is accomplished through a separate command that facilitates file organization in the system. Therefore, the primary role of the Type command is focused solely on the retrieval and display of text file contents.
