Answer 1

ruby 1.9.3p0 (2011-10-30) [i386-mingw32]

ruby: No such file or directory -- calc.rb (LoadError)

C:\Ruby Programs>ruby calc.rb.txt

One should not have to add the .txt extension while attempting to run the program from whithin the program's home folder. I have to though.

Answer 2

Did you call your file Calc.rb and saved it as a rb file to. becouse then its called internaly. Calc.rb.rb
and be sure to run cmd from desktop :D

Answer 3

In Terminal, did you change your current directory to your desktop before running your program ?

If your program is stored on your desktop, you first need to change directory to your desktop or your Ruby script will not be found.

$ cd Desktop
$ ruby calc.rb

Answer 4

If you have named your file "Calc.rb" you'll need to run ruby Calc.rb (capital "C").

Also make sure that you're navigating the /Desktop directory — e.g. type

cd ~/Desktop
ruby Calc.rb

You can use ls to get a list of all the files in the current directory. You could use that to see if the file you're trying to execute actually exists.
