1 - Check return values for every function that may fail.
3 - Add support for a default input string (when I will need it or if
8 - Fix the input shifting the line count by 1.
10 - Async line input? With fork(): I finally understood how it basically

18 number then the file name.
20 - Use this for io-grep
22 - Case insensitive match.
24 - Finish debugging memory with Valgrind
