Can Not Get Ruby to Run in Windows CMD Window

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 puts “Hello World” nothing happens. What am
I doing wrong?

Thank you.

Type Ctrl+Z after that and you would get the output. I would recommed
that
you type your programme in an editor and then run them using

c:> ruby yourprogramfile.rb

The best way however if you would like to learn ruby is use Interactive
Ruby
(IRB). Typing irb at the command prompt would give you the IRB shell.

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.
