title: Script scanning and adding string to lines such as *#include "abcd.h"
body: <p>I want to make a script that scans source files, and add a string to header lines such as from <em>#include "abcd.h"</em> to <em>#include "dir/abcd.h"</em>. It doesn't matter what header file it is, just anything after #include. Anybody have any idea how to do it with unix commands or I should write a script?</p>
