CSG6206 Advanced Scripting

Edith Cowan University 
School of Science
Unit Title Advanced Scripting Languages
Title Workshop 3

Learning Objectives

  • Analyse and evaluate scripted software in order to ensure reliability and security of developed solutions.
  • Create and deploy scripted software that utilises pre-existing software as part of its core functionality.

Task

Download the following image dataset, and extract it to a folder of your choice.

http://sipi.usc.edu/database/misc.zip

Create a bash script to accept a single argument, which is the path of the image folder where you extracted the images from the dataset above. Before you proceed with the script, you must check if the argument was passed to the script. If the user did not pass any argument, then display an error message and end the shell script with exit code 1. If an argument was passed, and it is a valid path, then proceed, otherwise end the shell script with exit code 2.

If the path is a valid path, then store the following fields for the image files in an SQLite database using insert command:

  • Image file name
  • Image file size in KB (you can round off to the nearest integer, and assume 1KB = 1000B)

After storing the above information in the database, use the select command to display all the records. Make sure the records are sorted according to the file size.

Title Workshop 2

Task

This task builds on top of previous week’s workshop. So as a pre-requisite you are required to have the misc.zip downloaded from the source website.

http://sipi.usc.edu/database/misc.zip

Use an inbuilt command to determine different colour models (e.g. colour, grayscale as shown in Figure1). Count the distinct colour models through a loop, and create a report (report format shown below). You should incorporate at least one function in your script, and string processing to ensure report output looks similar to Table 1. The table border lines are not required, but the columns and rows should be formatted to look like a table structure.
