Final answer:
To write 'Merry Christmas!' into a file using CLI, use the command 'echo 'Merry Christmas!' > holiday.txt'. For Unix-based systems and Windows, this will create or overwrite the file with your sentence. To append without overwriting, use '>>' instead.
Step-by-step explanation:
To write the sentence "Merry Christmas!" into a file using the Command Line Interface (CLI), you will need to execute a command in the terminal or command prompt of your operating system. On Unix-based systems, including Linux and MacOS, you can use the echo utility combined with redirection to achieve this. Below is the step-by-step explanation:
-
- Open your terminal or command prompt.
-
- Type the following command and press Enter: echo 'Merry Christmas!' > holiday.txt
-
- This commands uses echo to create the sentence and the '>' character to redirect the output into a file named holiday.txt. If the file does not exist, it will be created, and if it does, it will be overwritten.
For Windows users, the process is similar, and the same command can be executed in PowerShell or Command Prompt. Make sure you are in the directory where you want the file to be saved or provide a full path to where the file should go.
If you want to append the sentence to an existing file without overwriting it, you can use '>>' instead of '>'. For example: echo 'Merry Christmas!' >> holiday.txt
