Assignment 3 – Improving a Shell
In this assignment you shall take an existing implementation of a shell program and add some small improvements to it.
Preparation – Downloading, Compiling and Testing a simple Shell Implementation
Download and un-compress the following file: shell.tgz
The contents of the file are C sources that implement a simple shell. The contents are:
To compile these sources run:
gcc -o smsh1 smsh1.c splitline.c execute.c
To run the shell type:
./smsh1
A prompt of the form “>” will appear and then you can type commands like:
> ls
execute.c shell.tgz smsh.h smsh1 smsh1.c splitline.c
> wc execute.c
37 113 725 execute.c
The shell is terminated by typing the Control-D key (which signals end of input).
In this assignment you shall add functionality to this shell command. Each part builds upon the last.
Part 1 – Adding the ability to pipe commands to your shell (30 marks)
At the moment smsh1 doesn’t support piping of commands. So, for example, if you type:
ls | wc
at the prompt you get:
ls: wc: No such file or directory ls: |: No such file or directory
Write a new program called smsh2.c that is based on smsh1.c which performs all of the shell operations of smsh1.c but also allows commands to be piped as above so that if you type:
ls | wc
You get output like:
6 6 53
instead. You are free to add and modify files as required to accomplish this task. You must add a Makefile to your submission so that you can compile all the files for part1 by typing:
make part1
and the solution for part 1 can be run by typing:
./smsh2
Note, your program must still cater for all the behaviours that were correct in the original version of smsh1. You may find the lectures on piping useful in completing this part.
Part 2 – redirecton of stdin and stdout (30 Marks)
Your version of smsh2 currently doesn’t support redirection of output and input of commands such as:
ls > tmp.txt cat < tmp.txt | wc > out.txt
Copy your smsh2.c program from part 1 to smsh3.c so that it can handle redirection of standard input and standard output (don’t worry about stderr) using the “>” and “<” symbols. Again, you are free to add and modify files as required to accomplish this task (without affecting the ability of your code to correctly execute the behaviour required for part 1). You must add a Makefile to your submission so that you can compile all the files for part 2 by typing:
make part2
and the solution for part 2 can be run by typing:
./smsh3
Note, your program must still cater for all the behaviours that were correct in the original version of smsh2.
Part 3 – Adding Globbing – (20 marks)
Your version of smsh3 currently doesn’t support wildcards in command lines such as:
ls *.c cat *.h
Copy your smsh3.c program from part 2 to smsh4.c so that it can handle wilcard symbols in the command line. This expansion of wildcards is called globbing.
Note, you can use the glob system call (type “man -s3 glob” to find out more) that helps you to expand the wildcards to a list of actual filenames.
Again, you are free to add and modify files as required to accomplish this task (without affecting the ability of your code to correctly execute the behaviour required for previous parts). You must add a Makefile to your submission so that you can compile all the files for part3 by typing:
make part3
and the solution for part 3 can be run by typing:
./smsh4
Note, your program must still cater for all the behaviours that were correct in the original version of smsh3.
Detailed Submission Instructions
This assignment is basically like every other assignment you’ve ever done in CS… but just as a reminder:
The handin key for this exercise is: prac3. The following SVN commands will enable you to make a repository for this assignment. Please note the following:
Use the Unix “cd” command to change to the place where you want your exercise directory to be stored, then type these commands:
svn mkdir –parents -m “spc prac3 start” https://versioncontrol.adelaide.edu.au/svn/a1aaaaaa/2018/s1/spc/prac3
(creates this directory in your svn tree) svn co https://version-control.adelaide.edu.au/svn/a1aaaaaa/2018/s1/spc/prac3 .
(checks out a working copy in your directory) You can now begin work.
You can add a file to the repository by typing the commands:
svn add NAME-OF-FILE svn commit -m “REASON-FOR-THE-COMMIT”
where “reason-for-the-commit” should be some brief text that explains why you changed the code since the last commit. Note that you only need to add a file once — after that, SVN will “know” it is in the repository. You are now ready to commence working on the exercise.
The files you handin must include:
You do not have to include any of the add_one.c files or their variants… that you used for testing we will supply those.
Make sure you commit your files frequently, in case you have an accident. The University’s SVN repository is very reliable, and is backed up regularly — your computer probably is not… Regular submission is also a good defence against plagiarism by others, since the submissions are dated. We will test the behaviour of your scripts using an automated tester. The tester is thorough, and will find places where your scripts do not work correctly. If it finds an error, it will offer a (vaguish) hint. To encourage you to test your own work, the tester will not be fully available in the first few days before the exercise deadline.
The websubmission system will award up to 6 marks automatically. We will manually check the code for style and commenting and for code associated with the optional bonus exercise. Note that we reserve the right to deduct marks if your code does anything egregious or games the system to obtain marks.

Overview: To avoid issues with self-plagiarism, you will focus on a “mock” dissertation topic to guide your work in professional writing. This “mock” dissertation topic CANNOT be used as your exact dissertation topic. However, it should be viewed as your practice round of setting up a study and learning the steps involved in building a high-quality dissertation. In the discussion this week, you will indicate the topic you have chosen, the research question(s) you will use to explore the topic, and provide coaching to other classmates on their research questions.
As a reminder, here are the choices for your “mock” dissertation topic.
Students must choose from the listed topics of their school/program:

Exercise 1
In your local nuclear power station, there is an alarm that senses when a temperature gauge exceeds a given threshold. The gauge measures the temperature of the core. Consider the Boolean variables A (alarm sounds), FA (alarm is faulty), and FG (gauge is faulty) and the multivalued nodes G (gauge reading) and T (actual core temperature).
a. Draw a Bayesian network for this domain, given that the gauge is more likely to fail when the core temperature gets too high.
b. Is your network a polytree? Why or why not?
c. Suppose there are just two possible actual and measured temperatures, normal and high; the probability that the gauge gives the correct temperature is x when it is working, but y when it is faulty. Give the conditional probability table associated with G.
d. Suppose the alarm works correctly unless it is faulty, in which case it never sounds. Give the conditional probability table associated with A.
e. Suppose the alarm and gauge are working and the alarm sounds. Calculate an expression for the probability that the temperature of the core is too high, in terms of the various conditional probabilities in the network.
Exercise 2
Consider the problem faced by an infant learning to speak and understand a language. Explain how this process fits into the general learning model. Describe the percepts and actions of the infant, and the types of learning the infant must do. Describe the subfunctions the infant is trying to learn in terms of inputs and outputs, and available example data.
Exercise 3
Complete the missing step in the derivation of Equation (15.19) on page 586 of the textbook, the first update step for the one-dimensional Kalman filter.
Exercise 4
Consider an arbitrary Bayesian network, a complete data set for that network, and the likelihood for the data set according to the network. Give a simple proof that the likelihood of the data cannot decrease if we add a new link to the network and recompute the maximumlikelihood parameter values.
