Can Not Get Ruby to Run in Windows CMD Window

[Brad]

Hi All,

As the subject says.."Can Not Get Ruby to Run in Windows CMD Window"

I have Ruby installed: C:\Ruby

I was reading the Programming Ruby - The Pragmatic Programmers'
Guide. It says to bring up the Shell Prompt and type Ruby, then puts
"Hello World"

When I type Ruby <enter> puts "Hello World" nothing happens. What am
I doing wrong?

Thank you.

Brad

the ruby executable reads from stdin (and is totally silent) until you
send it a ctrl-D, I think. At that point it will process the text you
typed in.

In addition to what Kevin said, keep in mind that "ruby" runs the Ruby
interpreter, while "irb" runs the interactive ruby interpreter.
