How to append text to a file?

To append text to a file in a Unix-like environment, you can use the echo command with the >> operator. Here’s how you can do it:

echo "Your text here" >> filename.txt

echo "Your text here": This command outputs the text you want to append.
>>: This operator appends the output to the specified file instead of overwriting it.
filename.txt: Replace this with the name of your file.

If you want to append "Hello again!" to a file named example.txt, you would use:

echo "Hello again!" >> example.txt

This will add "Hello again!" to the end of example.txt. If the file does not exist, it will be created.
