Not really a Fedora related question really - it's been asked thousands of times on the internet too :) Generally a good idea to first use Google and post only if you don't find the answer - it's good for you - it sharpens your Google-fu and you learn a lot more :D

Easiest way is to use sed:

sed -i 's/ubuntu/basic/g' filename

This command will replace all "ubuntu" strings with "basic". If you want to replace only lines containg only the word "ubuntu", use

sed -i 's/^ubuntu$/basic/g' filename

(^ and $ characters represents begin and end of line).
