What command is used to clear the terminal screen?

The command used to clear the terminal screen is 'clear'. When you type 'clear' in a Linux terminal, it sends an escape sequence to the terminal, instructing it to wipe the visible content from the screen and reposition the cursor at the top left corner. This helps in providing a clean view, especially useful when the terminal has accumulated a lot of output.

The 'cls' command is commonly associated with DOS or Windows command prompts and is not recognized in a standard Linux terminal. The 'clean' command does not exist in typical Linux command sets and therefore cannot be used to clear the screen. The 'reset' command is used to reset the terminal settings and may clear the display, but its primary function is to restore the terminal to its default state rather than straightforwardly clearing the screen. Thus, 'clear' is the most appropriate and widely accepted command for this purpose in Linux environments.
