UNIX and LINUX

UNIX In 1969/1971, initially written in Assembly, In 1973, rewritten in C by AT&T Bell labs. (portability) OS designed to be

Programmer’s workbench multi-tasking, multi-user, time-sharing (interactive) platform-independent (portable) command line interpreter and pipe <-> single command Widely used in servers, networked workstation

UNIX and LINUX

LINUX In 1991, developed by Linus Torvalds UNIX-like OS (UNIX 의 한 종류 ) free and open source software Initially run on x86 (Intel) PC. Later, ported more server-level HW platforms and big

computers such as mainframe and supercomputers LINUX also runs on embedded systems Android system is built on LINUX kernel used in many kinds of servers

Database Servers, Web Servers, Business Servers,… Most internet environment is based on Client-server model

Main Advantage Security, reliability, low cost, multi-user (permission) support

Course Overview

Level : 3rd year CSE undergrad students

Topics : How to use UNIX and it’s utilities in OS user perspective

UNIX commands, utilities, shell, script, etc Internal structures and algorithms of UNIX kernel

process, file/directory structure, memory, etc UNIX System Programming (UNIX system calls) (UNIX Servers : APM – Apache, PHP, MySQL)

Objective Learn how to use UNIX/LINUX Understand internal structures of UNIX kernel Obtain the ability of programming under UNIX environment

Announcement

Class Website http://cau.ac.kr/~bongbong/linux13 Class information such as lecture notes can be

accessible through this website We will also use eClass to submit homework

Programming Assignments We encourage to study and discuss together for

doing programming assignments. However, you must do programming YOURSELF. You must not share any of source code with other

students. Any kind of academic dishonesty will be taken

seriously.
