I am brand new to Ruby, and I have downloaded and installed it and added Ruby to my PATH.
I opened a new command prompt and typed Ruby
, which put me into a session so to speak.
I then started to type various commands like, help
, update
, version
etc and it did nothing.
I then tried exit
, quit
and cancel
only to find that you have to use CTRL+C
to interrupt.
Anyways, did I harm the installation in any way by typing in those random commands? I never received any feedback after I typed the commands, just dropped a new line.

ruby is the compiler I believe. irb is the interactive console.
If you do Ruby myRubyFile.rb
it will run the file for you. This is useful in a batch script i have found.
for example if the ruby script renames some files and moves them somewhere you can put that in a bat or bash shell script.

When you type
ruby
like that, you're pointing the Ruby interepreter at . . . nothing!
Make a file called hello_world.rb, and put this line into it:
puts "Hello, world!"
Then type
ruby hello_world.rb
and see what happens.
