I want to know how I can find and replace a specific text in multiple files like in Notepad++ in the linked tutorial.
e.g.: http://cybernetnews.com/find-replace-multiple-files/
Here I use sed to replace every occurrence of the word "cybernetnews" with "cybernet" in every file with the extension, c, in the directory, /home/user/directory/.
find /home/user/directory -name *.c -exec sed -i "s/cybernetnews/cybernet/g" {} ;
A more generic variation where you search recursively from the directory of execution and operate on only regular, readable, writeable files:
find ./ -type f -readable -writable -exec sed -i "s/cybernetnews/cybernet/g" {} ;
