This repository contains material required to complete exercises for the OS lab in the 2020 summer semester, including exercise sheets and their associated materials. Note that some of this material is based on previous years.
Make sure to read this document carefully, as it contains vital information regarding the grading of exercises.
This schedule gives you an overview of the topics we will discuss on each date. It will be updated continuously throughout the semester. Note that exercises associated with a given date are to be discussed on that day, i.e., solutions for that exercise have to be handed in via OLAT by 17.00 on the previous day (Tuesdays).
| Date | Exc | Topic | Notes |

| 2020-03-11 | - | Introduction to UNIX, shell scripting | |
| 2020-03-18 | 1 | Shell scripting | |
| 2020-03-25 | Self-assessment due |
All programming exercise solutions you hand in must compile properly on the lab computers. The easiest way of ensuring this is by either developing your solutions on a lab computer directly (outside of course hours), or by connecting to ZID-GPL via SSH.
Note that the default version of the GCC compiler present on lab computers is
extremely outdated. You may load a never version by calling module load gcc/9.2.0.
NOTE: You have to be inside the University network to be able to connect via SSH. See here for more information.
To log into ZID-GPL via SSH, use the following command on Linux/Mac OSX:
ssh -l <username> zid-gpl.uibk.ac.at
On Windows, you can use Powershell (Windows 10) or a third-party SSH client such as PuTTY.
All programming exercises are conducted in C.
Your code should always compile without warnings, when passing the flags -Wall -Wextra -Werror -std=gnu11.
Make sure your code is properly
formatted using either your IDE/Text editor of choice, or by using a tool
such as clang-format. You can find an example
.clang-format file in this repository. Failure to
consistently format code may result in lower scores.
Furthermore, all submitted code must be accompanied by a GNU Makefile. That
is, your solution must be able to be compiled with a single call to make.
You can find an example Makefile and more information here.
Grades are based on the number of exercises you complete (1 point per exercise), the quality of your presentation of these exercises, and a written test. This test will be a programming assignment where you need to implement a small C program similar in scope to the exercises.
Please do not underestimate this test, and make sure to use the self-assessment exercise to understand whether you are ready to successfully complete this lab.
Attendence is mandatory, failing to attend more than two times will likely result in a failing grade. Exercises only count as completed if the lab in which they are presented is attended.
Note: In order to successfully complete this course, you need to get a positive grade on the test and the number of exercises solved and their presentation. Both tests and the exercises/presentation contribute to your final grade.
