File Analyzer

General Information

Group project for the Operative System (OS) course of the Bachelor’s Degree in Computer Science at University of Trento.

The main focus of this project is to count the occurrences of ASCII characters inside one or more files.

To make all as extensible and modular as possible, we have developed several components, each of them having specific tasks. In particular:

Counter spawns the reporter and the analyzer.
Reporter creates the terminal user interface Tui and communicates with the analyzer.
Analyzer takes all inputs from the user and finds all files given a directory. Then, while files are being discovered, analyzer sends founded ones to managers.
Manager takes files and split them in several works. A work starts from a specific point of the file and ends in another. When works are ready they are sent to workers.
Worker takes the file, the start point and the end point. After that he reads the portion of the file

The program structure is depicted in here:

Program Structure

We have developed an efficient multithread and multiprocess program in C to analyze recursively the files contained inside a folder and produce statistics about them — average of 51 files/seconds.
User interaction is supported through a Terminal User Interface (TUI) to handle which files to consider, the number of processes to be spawned, the statistics to be shown, and to traverse the local file system.

A glance of the program execution is shown here:
