Let's run through the shots.
CASE FILE / COMP2041 / Software Construction / Unix
GiveUnix Assignment Submission & Automarking System
Recreated a Unix-style assignment submission, testing and automated marking system as a collection of interoperating POSIX shell utilities.
01–02 / OPENING SEQUENCE
Establishing the world
01 / Establishing Shot
The Problem
The system needed to reproduce an assignment-submission workflow through multiple independent Unix commands while maintaining consistent shared state.
02 / Wide Shot
The Context
The project was completed for COMP2041 and focused on constructing a larger tool from small shell programs and standard Unix facilities.

Role notes
DIVAKAR DESSAI
I implemented the command-line utilities, filesystem organisation, validation rules and automated testing and marking behaviour.
04 / CLOSE-UP
THE ENGINEERING CHALLENGE
Although implemented as separate programs, every command needed to agree on repository structure, submission state and expected edge-case behaviour.
05 / TRACKING SHOT
THE APPROACH
A plan emerges.
I used a shared directory structure as persistent state and implemented each operation as a focused POSIX shell command that interacted with that structure.
06 / INSERT SHOTS
KEY FEATURES
The system takes shape.
07 / DIRECTOR'S NOTES
DESIGN DECISIONS
Things we decided along the way
01
Built multiple small commands instead of one monolithic script.
02
Used filesystem state as the communication layer between commands.
03
Relied on standard Unix behaviour such as exit statuses and command composition.

08 / RETAKES
WHAT WENT WRONG
Naturally, not everything cooperates.
09 / FINAL SHOT
THE OUTCOME
ProblemBuildOutcome
01
Built a complete multi-command Unix application.
02
Developed stronger POSIX shell skills.
03
Learned how complex developer tooling can emerge from small composable utilities.
