Equivalent of "which" in Windows Command Shell

I have always missed the which utility of Unix under Windows, which doesn't seem to have built-in equivalent. So, when I came across batch script parameter modifiers while browsing Windows shell scripting, I decided to write a Windows equivalent of which:

@echo off
rem --------------------------------------------------------
rem File: which.cmd
rem Description: Windows equivalent of Unix which command
rem Author: Pankaj Kumar

rem ---------------------------------------------------------
if "%1" == "" goto noArg

set fullpath=%~$PATH:1 if "%fullpath%" == "" goto notFound echo Found in PATH: %fullpath% goto end
:noArg echo No Argument specified goto end
:notFound echo Argument "%1" not found in PATH
:end endlocal

To use this command, either do a Copy-Paste of the above source code (but, beware of the formatting tags) or download which.cmd.
