That is a valid way of doing it. I would however consider this:

echo "string" >> file.txt

The quotes make it possible to handle more than one word (in the case of echo, that works anyway, but it's good practice to always use it). You should also distinguish between > and >>

>> on the other hand appends your string to the bottom of your file
