 =====Background===== =====Background=====

-Copy this file into your project directory.+Copy these file into your project directory.
  
 There is also a **MANIFEST** file in the parent directory (the **pct0/** sub-directory), which will contain MD5sums of the various puzzle keys, provided to help you in verifying your puzzle key. There is also a **MANIFEST** file in the parent directory (the **pct0/** sub-directory), which will contain MD5sums of the various puzzle keys, provided to help you in verifying your puzzle key.
 +
 +For this project, the only puzzle you HAVE to solve in order to be eligible for full credit will be the one contained in the **puzzle** file.
 +
 +Should you desire, there's an opportunity to gain some bonus points, which can be earned by successfully solving and documenting your solution to the puzzle contained within the file **bonus** and reporting it to me as appropriate.
 +
 +As you gear up to work on the project-required puzzle (or additionally the bonus puzzle), I have provided a sampling of practice puzzles that you can try your hand on in order to get more experience working with these type of puzzles. Doing them will not net you any points, nor will not doing them diminish your totals for this project. I would recommend doing them, though, as the more exposure you have within this domain, the more patterns become identified, further facilitating your chances of success.
 =====Process===== =====Process=====
-In the **TASK** file, you will be given a set of source quantities/units and destination units you need to construct command-lines for to solve, using the tools provided to you in the **unittools** suite. You will also want to make use of pipes and command expansions in your solutions.+Solve and document the puzzle.
  
-As an example, take the following (formatted is it would appear in your **TASK** file):+On your own.
  
-<code> +Seek to discover and explore and understand, NOT to just come up with an answer. 
-task: 0 +=====Your Solution===== 
-precision: 3 +As this project focuses more on the critical thinking process than being heavy in unravelling a problem using UNIX commands, your solution will be in 2 parts:
-input_value: 35 +
-input_unit: cm +
-output_unit: ft +
-chain_delim: " >> " +
-</code>+
  
-With these in mind, we can set about solving this problem, using the tools in combination to arrive at the desired result.+  * your puzzle key, in a textfile called 'puzzle.key' containing ONLY the capital letters corresponding in order to the 0-9 values (and a trailing newline). 
 +  * your documentation of your solving and exploration of the puzzle. If you did this on paper, I'll want it digitized and submitted as a file with this project. The file, if is text form, should be called 'puzzle.solution'; if an image, please append the image format to the end of the filename.
  
-A potential solution would be as follows:+====puzzle key==== 
 +As indicated, you are to place the determined key to your puzzle in a regular text file called 'puzzle.key', and will contain ONLY the capital letters, in order from 0-9, of your puzzle (and a trailing newline). 
 + 
 +For example, using the example puzzle above: 
 + 
 +|  0  |  R  | 
 +|  1  |  B  | 
 +|  2  |  V  | 
 +|  3  |  G  | 
 +|  4  |  P  | 
 +|  5  |  M  | 
 +|  6  |  O  | 
 +|  7  |  L  | 
 +|  8  |  J  | 
 +|  9  |  K  | 
 + 
 +We'll want to put them, in order, in our key file:
  
 <cli> <cli>
-lab46:~/src/unix/upf1$ echo "35" | cm2in +lab46:~/src/unix/pct0$ echo "RBVGPMOLJK" > puzzle.key 
-13.78 in +lab46:~/src/unix/pct0$ 
-lab46:~/src/unix/upf1$ echo "13.78" | in2ft +
-1.15 ft +
-lab46:~/src/unix/upf1$ +
 </cli> </cli>
  
-But that's not very optimized. We could instead do something better, like:+Want to know what a proper 'key' file should look like? This:
  
 <cli> <cli>
-lab46:~/src/unix/upf1$ echo "35.000 cm" | cm2in OPTIONS | in2ft OPTIONS +lab46:~/src/unix/pct0$ cat puzzle.key 
-35.000 cm >> 13.780 in >> 1.148 ft +RBVGPMOLJK 
-lab46:~/src/unix/upf1$ +lab46:~/src/unix/pct0$ 
 </cli> </cli>
  
-Note that with **precision**, you need to instruct the tools to display out to the specified number of decimal places.+JUST the letters (and a trailing newline).
  
-We'll want to record our command-lines in the appropriate place. Since this is task #0, we'll want to record it in a file called: **task0.cli**, which should basically just contain the command-lines you ran, merely placed in a text file.+====solution documentation==== 
 +As stated, a very large part of this project's evaluation will be based on your clear and detailed documentation of how you determined each letter's mapping in the solution key of your puzzle.
  
-For final output, we'll want to display the chain of conversions we went through. So, for this above example:+Just providing the 'key' will not result in success. 
 + 
 +Your documentation should, while there may be supporting information, provide some identified path that showed the steps you went through to identify each letter, be it directly or indirectly. 
 + 
 +You are free to write out your solution with pen on paper (that is how I usually do these puzzles); but if you do so, you MUST digitize it and submit it as an image file when you submit this project. 
 + 
 +The aim here is not to dump a bunch of data on me, but instead present me with connected and pertinent information that documents your process of progression through the puzzle from start to finish. 
 +=====Verification===== 
 +Want to check to see if your key is correct (ie all letters in the right order)? 
 + 
 +====Generate MD5 sum==== 
 +You can do so, by generating an MD5 sum of your 'key' file and grepping for it in the MANIFEST file:
  
 <cli> <cli>
-lab46:~/src/unix/upf1$ ./task0.cli +lab46:~/src/unix/pct0$ md5sum puzzle.key | cut -d' ' -f1 
-35.000cm >> 13.780in >> 1.148ft +1395327d0826e3145b4f285a2b936707 
-lab46:~/src/unix/upf1$ +lab46:~/src/unix/pct0$ 
 </cli> </cli>
  
-Basically, each task#.cli will be its own script. If we were to execute it, the correct result should be produced.+Obviously, YOUR MD5 sum will be DIFFERENT from this, because this is the MD5 sum of the puzzle key explored at the top of this project page.
  
-=====Your Solution===== +NOTE: MD5 sums of your bonus and practice puzzles are also present in the MANIFEST file, so you can perform verifications on them in the same manner.
-As this project focuses more on the critical thinking process than being heavy in unravelling a problem using UNIX commands, your solution will be in 2 parts:+
  
-  * your puzzle key, in a textfile called 'key' containing ONLY the capital letters corresponding in order to the 0-9 values. +====Look for matching MD5 sum in MANIFEST==== 
-  * your documentation of your solving and exploration of the puzzle. If you did this on paper, I'll want it digitized and submitted as a file with this project.+Let's say the path to the **pct0/** sub-directory of the public directory is in a variable called PROJECTDIR; if so, you can check your MD5 sum for a match in MANIFEST as follows:
  
-====puzzle key==== +<cli> 
-As indicated, you are to place the determined key to your puzzle in a regular text file called 'key', and will contain ONLY the capital letters, in order from 0-9, of your puzzle.+lab46:~/src/unix/pct0$ cat ${PROJECTDIR}/MANIFEST | grep $(md5sum puzzle.key | cut -d' ' -f1) && echo "MATCH FOUND" || echo "NO MATCHES FOUND" 
 +MATCH FOUND 
 +lab46:~/src/unix/pct0$  
 +</cli>
  
-For example, using the example puzzle above:+If you have a match, congratulations, you unravelled the puzzle correctly. Just remember: evaluation is heavily based on your documentation of the process, not whether or not you can arrive at the correct answer key.
 =====Submission===== =====Submission=====
-By successfully performing this project, you should have a set of task#.cli files (one for each task). You will want to submit these, along with a **upf1steps** file.+By successfully performing this project, you should be submitting files that satisfy the following requirements: 
 + 
 +  * a 'puzzle.key' file formatted as indicated elsewhere in this project document 
 +  * a 'puzzle.solution' file containing organized and informative detailing of your path to solution 
 + 
 +Additionally, although optional, if you'd like to do similar for the bonus puzzle: 
 +  * a 'bonus.key' file formatted as indicated elsewhere in this project document 
 +  * a 'bonus.solution' file containing organized and informative detailing of your path to solution
