Find and replace via SSH

[marquis_ce]

It is possible to find a spesific file in whole server

find / | grep index.html 

and also it is possible to delete a spesific file in whole server

find / -name index.html -type f -ls -exec rm -f {} \; 

I wonder if it is possible to find a word in source code of all html files in the server.
For example i want to change a bg color of a site in all html pages.

If your are using a recent linux version you can execute the following to search all files recursively under the current directory.

grep -R bgcolor *

Alternatively you can execute

find / -name \* -exec grep -R {} \;
