Learning how to create and save .rbs

ruby-talk
1

So I am trying to create and run an .rb, a basic stepping stone.
After I typed and saved my .rb it ran like this-

irb(main):oo1:0) ruby 01hello.rb
Syntax Error: (irb):2: syntax error, unexpected tIDENTIFIER, expecting
$end
ruby 01hello.rb

Or

irb(main):001:0) ruby Helloworld.rb
NameError: uninitialized constant Helloworld
        from (irb):1
        from C:/Ruby/bin/irb:12:in '(main)'

I've been playing ping-pong with these two errors and others like them
but can't seem to get the .rb to jut run.
Any and all advice,help,or direction is appreciated.

Could you post the source of 01hello.rb

It seems you are trying to run ruby being already in irb. You should run
"ruby 01hello.rb" outside irb.

path/to/folder $ ruby 01hello.rb

Hello,

the problem is that you try to run your ruby script files from irb. If you just want to run your scripts, run them from the command line like you tried in irb - if you just type "ruby" in irb you'll get the error that ruby doesn't know a variable/method "ruby"..

Your two errors are completely unrelated to that, though. The first one tells you that the parser doesn't know what to do with the . in the line, while the second says that there simply is no constant Helloworld.

Regards, Calvin

puts "Hello and welcome to Ruby Programming."

Thanks for the advice I'm experimenting with the windows command prompt
now.
