Let, I have a file (text.txt) where i want to replace specific lines "GOOGLE" word to "DUCKDUCKGO".

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

Above command will change/replace every line. What can i do ?

Also i want a little bit different one,

I have a line "/var/www/html/web" which i want to be replaced with "/home/fahad/html/web" from specific line maybe 19 .... What can i do ? Please help me on this ...

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.
