There's been a murder in Terminal City, and TCPD needs your help.

To figure out whodunit, you need access to a command line.

  • Open a Terminal, go to the location of the files (remember your cd command), and start by reading the file instructions.

    • One way you can do this is with the command:

      $ cat instructions
  1. To get started on how to use the command line, open cheatsheet.md or cheatsheet.pdf. Some easy ways to do this from the command line are to type:

    $ cat cheatsheet.md


    $ nano cheatsheet.md

    or even

    $ open cheatsheet.md
  2. Don't use a text editor to view any files except for these instructions, the cheetsheet, hints, or spec/solution_spec.rb.

  3. Once you think you have the solution, open up spec/solution_spec.rb and make the test pass by replacing the __ with your solution as a string.


If you do get stuck while trying to figure out who the murderer is, you can use the hints that have been provided for you! They are denoted with a filename called hint<number>. There are 8 hints total - simply replace <number> with a number 1 through 8. NOTE: try to do as much as you can without the hints!

To access a hint from the command line, simply type:

cat hint1


nano hint1


open hint1
