Help running programs from Mac Desktop in Terminal

Ruby
1

I am new to Ruby. My version is 2.0. I am running on Yosemite OSx.

What I am trying to do is a write a program in the text editor, save it
in .rb format, and run that program using the terminal on Mac.

I made a simple program …

puts “hello world”

and then saved it (to my desktop in a folder called ruby) as hello.rb

Now, I go into terminal and want to execute the “program”.

I have tried the following methods with no prevail…

$ ruby hello.rb <-- does not work…

It returns an error saying —> "’$’ is not allowed a global variable
name "

I’ve tried …

cd ~/
ruby hello.rb <----- did not work…

It returns no error, in fact it continues onto line 3 without noticing
reacting to what I typed.

PLEASE HELP. I am enjoying learning about Ruby so far, and am stuck at
this section of the book because of this problem!

Do not type the leading $. This is a common
convention used is denote what follows is a command
to be run.

Read the tutorial linked above, it gives an introduction to the command
line. Also, make sure you goto (“cd”) to the directory containing your
script.
