ruby add content to file

To add content to a file using Ruby, you can follow these steps:

1. Open the file: First, you need to open the file in write mode. You can use the File.open method to achieve this. For example, to open a file named "example.txt" in write mode, you can use the following code:

file = File.open("example.txt", "w")

1. Write content to the file: Once the file is open, you can use the write or puts method to add content to the file. The write method writes a string to the file, while the puts method adds a new line after the string. Here's an example that adds the text "Hello, World!" to the file:

file.write("Hello, World!")

1. Close the file: After you have finished writing the content, it's important to close the file using the close method. This ensures that all the changes are saved and the file is properly closed. Here's how you can close the file:

file.close

By following these steps, you can add content to a file using Ruby. Remember to handle any potential errors that may occur, such as file not found or permission issues, by using exception handling techniques like begin and rescue.
