fix(command-line): format split in chunks patterns

The format command now splits all the array containing all the urls and patterns given, in smaller chunks arrays, executing the command on each chunks. This prevent to have too long argument on the command for the terminal, which can lead to error on specific OS. The chaining of command is transparent for the user. close #511
