## COP4342 - 2017 Spring Fibonacci Sequence in Bash

Your assignment is to login into 45.56.74.139 and write a script "bin/fib.sh" that computes the Fibonacci sequence (OEIS A000045).

Your script should accept a single command line argument. This argument will be the length of the Fibonacci sequence to compute. Call that value "COUNT".

Your script should compute all of the Fibonacci numbers from fibonacci(0) to fibonacci(COUNT-1).

Please don't worry about overflow for Fibonacci numbers greater than or equal to 93 unless you would like to.

Also, you may not use any other programming language for this exercise, including such calculator languages as "bc", "dc", or "gp". This exercise must be done solely use Bash constructs.

You may do as much (or as little) argument checking as you like. It's not required for this exercise, but it's always a good idea.

Submission: Please submit your fib.sh script on Blackboard; also, please leave it in ~/bin so that I can test it on 45.56.74.139.
