    sed -i 's/GOOGLE/DUCKDUCKGO/' text.txt

    will only replace the first "GOOGLE" word

    Second answer.

    sed -i '19s/\/var\/www\/html\/web/\/home\/fahad\/html\/web/' text.txt

    It will replace /var/www/html/web with /home/fahad/html/web in line 19. If you are not sure, remove option -i so it will display the result. After you sure you can add -i again.
