It runs with MS.NET too, you just need to call native executables

Sure. You just compile with mcs or csc (they generate the same
portable binary) and run with .net or mono (both implement the
Process/ProcessStartInfo classes in their base class libraries in the

Maybe you can extract ideas from these projects:
http://www.codeproject.com/csharp/shell_net.asp - "Shell.NET is a set
of console applications written in C#" including grep
http://www.codeproject.com/csharp/wingrep.asp - "A C# Grep Application"

Then you'll need to have cygwin's grep or some other executable ready
for you to call, it doesn't look like the best solution.

See the above projects for ideas. The important fact is that the Base
Class Library has classes to easily read text files, recurse into
directories and apply regular expressions so writing such a tool is
just a glue-the-right-parts exercise.
