Getting a Scala interpreter to work

Question

I\'m very new to Scala. I have downloaded it, got it working in Eclipse where I\'ll be developing it; but I can\'t make it work in Terminal.

All sites and books say

My way of making Scala run every time you type "scala" in Terminal was to add the path not to the .bashrc file but to the /etc/paths one.

1. Download the latest Scala binary from www.scala-lang.org/download
2. Unzip the binary file
3. Move the unzipped folder (named scala-2.11.2) to the /usr/bin/ or some other directory of your preference.

4. Then open the /etc/paths file with nano:

   sudo nano /etc/paths
   

5. and add this line to the end:

   /usr/bin/scala-2.11.2/bin
   

6. Press Ctrl+X to exit nano and answer "Yes" when prompted to overwrite the file

7. Then restart Terminal and once you type:

   scala
   

   you will get the scala command line that looks like this:

   Welcome to Scala version 2.11.2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_05).
   Type in expressions to have them evaluated.
   Type :help for more information.

I hope this helps.
