Linux System Programming

This repository includes three fully functional system-level C projects, each developed to demonstrate practical use of Linux system calls and low-level programming

Project include:

• File Organizer: Sorts files by extension via a custom tree and arrange command-line tool
• Cleanup Daemon: Runs background processes that monitor and organize directories in real time
• EXT2 Image Analyzer: Parses raw ext2 filesystem images to display structure and contents without using external libraries

Each project is implemented from scratch in C, runs in the terminal.

Projects

1. File Organizer: ssu-cleanup

• This CLI-based tool organizes files in a given directory based on their extensions.
• This project focuses on file I/O, command parsing, and linked list representation of directory structures.

2. Cleanup Daemon: ssu-cleanupd

• This tool runs as a daemon that monitors specified directories and organizes newly added files periodically.
• This project focuses on daemon process management, configuration handling, file locking, and exception handling in a system environment.

3. EXT2 Image Analyzer: ssu-ext2

• This CLI program parses and analyzes ext2 disk image files to display directory structures and file contents.

Requirements

• Linux-based OS (e.g., Ubuntu)
• gcc
• Each project includes its own Makefile
