Try ruby -e 'puts "Hello, world!"' (You need to give the name of the ruby interpreter so Windows knows what to execute, and the tell Ruby that it should execute the string that follows. That's what the -e is for. ) James -- http://www.ruby-doc.org - Ruby Help & Documentation http://www.artima.com/rubycs/ - Ruby Code & Style: Writers wanted http://www.rubystuff.com - The Ruby Store for Ruby Stuff http://www.jamesbritt.com - Playing with Better Toys http://www.30secondrule.com - Building Better Tools

And you should use 'puts' instead of 'Puts'.

Have you installed Ruby? Use the one-click installer: http://rubyforge.org/frs/?group_id=167 And create a new file and put this in it: puts "Hello World!" gets and save and double-click it.

The program you're using, "cmd" is the Windows command prompt. When you type in a command, it checks from two places whether that command is valid: The first place is a set of commands that are inside of the program (such as "dir", "cd", et al). These commands let you look superficially through the filesystem. The second place is designated by what is called a "PATH" environment variable. This tells the program "cmd" where to look in the filesystem for the programs you try to run. The program "ruby" is not in your "PATH". That means that the command prompt cannot find the program. To change this you must first know where you installed ruby to. In the below instructions, it is assumed you installed ruby to "c:\ruby\". Choice 1: Add the ruby binary to your PATH environment variable To change your path variable, hold down the "windows key" and press the "pause break" key. It'll open up the system properties dialog. Now click on the "Advanced" tab. There should be an "Environment Variables" button. Click on it and look for "Path". Then click "Edit". For the variable value, add on to the end ";c:\ruby\;c:\ruby\bin\" without the quotes. You need the semicolons to separate the two. Choice 2: Write a batch file (.bat file) to put somewhere in your PATH to run Ruby without changing your PATH environment variable If you don't want to add Ruby to your PATH for whatever reason, you can just put a batch file in a place that is already in your PATH. The directory "c:\windows\system32\" should be in your PATH already, so go there and create a text document with notepad. In the text window put the line "c:\ruby\bin\ruby.exe" without quotes and save it as "ruby.bat" in the "c:\windows\system32" directory. Make sure there's no .txt on the end of "ruby.bat". Now when you do what James B. told you above it will work.
