Shell.NET - A Collection of C# Command Line Utilities

The Code Project - Shell.NET - C# Programming

"Shell.NET is a set of console applications written in C#. It features some classical Unix applications like basename, cal, grep, tr, uniq, wc, but also some very unique tools like RunScript or TextTransform, a awk-like text processing application accepting scripts written in any of the languages supported by the installed .NET Framework.

There are some interesting items in this collection, all of which include the source (which makes me a happy coder... :)

Looks like the source is a couple years old, but as long as we HAVE the source and it works, that's just fine.
