How to append text to a file in Linux?

In Linux, you can use the >> operator to append text to a file.

For example, suppose you want to append the text “Hello, World!” to a file named file.txt, you can use the following command:

echo "Hello, World!" >> file.txt

After running this command, the text “Hello, World!” will be appended to the end of the file.txt file. If the file.txt file does not exist, the command will create a new file.

Also, if you want to append the output of a command to a file, you can use the following command:

command >> file.txt

The command being executed will have its output appended to the end of the file.txt file.
