Create linux command line utility that allows to search and replace recursively

I need a linux command line utility binary application with source code that allows me doing this. searchreplace *.php [login to view URL] [login to view URL] -r -y [login to view URL] [login to view URL] , our program will need to find that [login to view URL] string (large string) in all files [login to view URL] , our program will replace the found string with the replace with one , if the [login to view URL] file is empty we will replace with empty (so clear the found string on the files) -r = recursive search , otherwise it will stick to the current directory -y = auto confirmation , otherwise manual confirmation y/n [login to view URL] , our program will create an output log It should be able to run on command line and accept params. I am not looking for a .sh batch script , I need a compiled linux binary application that can be run from the command line and it's source code Must work in CentOS , Ubuntu and Debian as well. I am going to use this utility to search and replace recursively in multiple files to fix scripts, can provide a sample .php with text string that needs to be cleaned / replaced, just bid and message me. I can accept max $100 for this project.
