# 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](src/date.c);

2. [uptime](src/uptime.c);

3. [ls](src/ls.c);

4. [cp](src/cp.c);

5. [rm](src/rm.c);

6. [mv](src/mv.c);

7. [cat](src/cat.c);

8. [mkdir](src/mkdir.c);

9. [rmdir](src/rmdir.c);

10. [chmod](src/chmod.c);

11. [chown](src/chown.c);

12. [ps](src/ps.c).

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](http://man7.org/linux/man-pages/dir_section_2.html);

2. [Operating Systems Concepts (by Abraham Silberschatz)](https://www.amazon.com/Operating-System-Concepts-Abraham-Silberschatz-ebook/dp/B07CVKH7BD/);
