When I type this into the terminal it works... but I am wondering if I
am going about things the right way:
$ /opt/local/bin/ruby1.9 -v
$ cd
$ cd Desktop
$ cd programs
$ ruby1.9 calc.rb
then the math equation answer from calc.rb shows up in the terminal.
Am I correct in thinking that ruby 1.9.1 is the ruby that is working
and not ruby 1.8.6?
Thank you for your time,
Calvin Stephens
It's likely but program names can be changed arbitrarily. If you want to be sure you can easily find out by entering
ruby1.9 -v
Kind regards

I am also wondering if I could just type this into my terminal to get
ruby1.9 to run a ruby file:
$ cd
$ cd Desktop
$ cd programs
$ ruby1.9 calc.rb
Is this correct or incorrect?
Thanks for your time,
Calvin

Yes, that's correct, as long as ruby1.9 is in your path.
Also you can say cd ~/Desktop/programs rather than three separate cds.
And don't miss tab completion, if you're using bash.

Hi Martin,
I am using bash... what is "tab completion" and how do I do it?

Hi Martin,

Start typing enough of the directory name, and by pressing tab bash will
finish it for you -- if what you have is enough to identify it uniquely.
For example, if you are in /home/me and you want to get to
scripts/ruby/tests, try "cd scr" don't press return, press tab and scr
will expand to scripts, then "/ru" and do the same thing, then "/te" tab
and you'll have
cd scripts/ruby/tests
now you can hit return, and all you actually typed was cd
scr[TAB]/ru[TAB]/te[TAB]
Hopefully that is clear enough...a lot of CLI (and GUI) apps use tab
completion (eg, google).
