I wanted to sum the total lines of code in files in a given folder. I thought that writing my own program to do this would be faster than looking for it on the internet, so here's what I came up with

Spoiler: here's the one line of code.


using System;

using System.Linq;

using System.IO;



class Program

{

    static void Main(string[] args)

    {

        Console.WriteLine(

            Directory.GetFiles(

                Environment.CurrentDirectory, "*", 

                string.Join(" ", args).Contains("/s") 

                    ? SearchOption.AllDirectories : SearchOption.TopDirectoryOnly)

            .Select(f => File.ReadAllLines(f).Length)

            .Sum());

    }

}

Here's mine:


find . -name "*" | xargs wc

Throw a tail in there if you only want the sum, a -l if you only want the lines.

Apparently somebody already thought of that.

Your code should be:
find . -name "*" -type f | xargs wc

Plus you need to take into account the "recursive" /s parameter (in your case to ignore it). I've just posted my approach in groovy on dzone regarding this issue.
