Implementation of various Unix system programs

Unix system programs

This repository contains the implementation of different Unix system programs in C. They were written for an assignment of the operating systems classes I took. The goal is to use and understand the main POSIX system calls.

Uploaded here for anyone who appreciates operating systems or wants a quick reference.

Implemented programs:

1. date;
2. uptime;
3. ls;
4. cp;
5. rm;
6. mv;
7. cat;
8. mkdir;
9. rmdir;
10. chmod;
11. chown;
12. ps.

Note that these programs are simplified versions of the original ones since they were written for learning purposes.

Useful materials:

1. Linux man-pages: section 2;
2. Operating Systems Concepts (by Abraham Silberschatz);
3. Modern Operating Systems (by Andrew Tanenbaum).
