Project: THE PUZZLE BOX
A project for CSCS1730 UNIX/Linux Fundamentals by YOUR NAME OR GROUPMEMBER NAMES during the SEMESTER YEAR.
This project was begun on DATE and is anticipated to take X AMOUNT OF TIME. (Upon completion you can correct this with the actual length).
Objectives
To demonstrate understanding of tools through application of skills, observation, and the ability to reference necessary documentation.
Prerequisites
In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:
- know how to use the command-line
- familiarity with using command-line arguments to alter default behaviors of commands
- know how to bring up and read a manual page
- familiarity with other resources that provide documentation or usage information
Background
The purpose of this project is to allow me to explore a file and figure out what it says. To do this I will have to use my knowlege of regex's and zipping to decode the special message.
Scope
To apply skills learned in unraveling the puzzle that isn't as it may seem.
Located in /var/public/unix/puzzlebox/ is a filed called courses.html … have at it.
Attributes
State and justify the attributes you'd like to receive upon successful approval and completion of this project.
- commands: utilization of commands to accomplish the task
- files & directories: recognize what is being dealt with and act appropriately
- text processing: retrieve/manipulate text
- the UNIX shell: perform necessary command-line manipulations to accomplish the task at hand
Procedure
I copied the file. renamed it to the appropriate file type. The file type is found by using the command “file” and the the name of the file. After that i unzipped it using the appropriate type of zip command (gunzip,tar,zip). after unziping it i had to repeat this pattern except copying it until it was a text file and then i could cat it. I had to cat it, then pipe it to “sed” multiple times until i removed all the flaws. after that i had to reverse it and using rev and then redo the whole thing in one line and send it all to a file.

Reflection
This project was very fun but annoying because I kept forgetting to use the “file” command so I got very frustrated but Matt helped me out by dropping hints.
