Recursive search inside the content of files under current directory - then view the result paginated with 'less'

This command will traverse all of the folders and subfolders under current working directory. For every file inside it, it will do a search inside the content of the file for a specific term 'what'. Then it will print a list of the lines that contain that term (and match that pattern). Each matching line will be preceded with the path and name to the file and then the line number iside taht file wehre the pattern was found. Then the actual content of the matching lien will be printed.

The output will be piped throug less, so that the user can scroll through it if it goes beyond the limits of the current display window.
