The code snippet cat file.extension reads the contents of a file named file.extension and outputs (prints) the content to the terminal or standard output.

• cat: A shell command in Unix/Linux systems to concatenate and display the contents of files.
• file.extension: The name of the file whose content is to be read (it could have any extension, like .txt, .log, etc.).

For example, if file.extension contains the text "Hello, World!", running cat file.extension would display:

Hello, World!

If the specified file does not exist, an error message (e.g., No such file or directory) will be displayed.
