LINUX (LIH-nuks)
 Unix

Originally developed at AT&T as a multitasking
system for minicomputers and mainframes in the
1970’s.
 Linux




Developed primarily be Linus Torval.
Inspired by Minix.
Kernel uses no code from AT&T or any other
proprietary source.
Developed by a group of volunteers, primarily in
the Internet, who exchange code, report bugs and
fix problems.
What is so special about Linux.
Linux is said to be:
Reliable.
 Simple.
 Free!
 Runs on a variety of platforms.
 considered the most important free
software achievement.
 Able to turn any 80386 or better PC into a
workstation.

LINUX
 Features:






Complete multitasking, multiuser OS.
Compatible with Unix standards.
Supports virtual consoles.
Supports various file systems for storing data.
Provides complete implementation of TCP/IP
networking software.
Include device drivers for many Ethernet cards.
LINUX
 Features (cont.)

Kernel




is developed to use protected-mode features of Intel
80386 and better processors.
supports demand-paged and loaded executables.
supports copy-on-write pages.
Linux can coexist with other OS on the same
machine.
GNU/Linux K Desktop
Environment
 KDE is a powerful GUI desktop environment for
Unix workstations.
 Provides ease of use, contemporary functionality,
and the technological superiority of the Linux OS.
 KDE is an internet project that is "Open" in every
sense.
 All KDE sources are open to everyone and may be
distributed by anyone subject to the well know GNU
licenses.
 KDE is a mature desktop suite.
 Visit WWW.KDE.ORG for further information.
The GNU Project
 Launched in 1984 to develop a completely Free Unixlike operating system: The GNU System. Many
flavors of the GNU system are currently in use, i.e.
Caldera, Redhat, Corel, etc.
 These GNU Systems use the Linux Kernel, these
systems are incorrectly called "Linux", they should be
called GNU/Linux systems.
 GNU is "Copylefted". Copyleft uses copyright law in
reverse. It allows software to be used, modified, and
distribute modified versions. Modified versions may
not add restrictions of their own.
 Visit www.gnu.org for more information.
Current KDE Distribution
Includes the following packages:
 KDE-Libs: Various Run-time libraries
 KDE-Base: The base components
 KDE Graphics: e.g. Kpaint, Kfax, Kghostview
 KDE Utilities: Kedit, KCalc, Knotes
 KDE-Multimedia: KMidi, Kmodplayer,
Kmixer, KSCD
 KDE-Games: Kasteroids, Kpat, Ktetris
 KDE-Admin: Various rools to aid system
administration
Current KDE Distribution
Includes the following packages:
KDE-Network: Kppp, Krn, Kmail
Most current distributions of Linux Use
a modified version of KDE. Corel calls
its version Enhanced KDE.
Visit Linux.Corel.com, Linux.com,
Linuxworld.com for more information.
Demonstration.
The Value of Linux Application
 Linux is a complete multitasking , multi-user
operating system. It supports various file
system and applications.
 Linux is much more compact and runs
similar applications much faster than
Windows.
Lower Cost
 Most of Linux software and applications are
inexpensive, which you can purchase in
diskette or CD-ROM format. E.g. CorelDraw,
WordPerfect 8, Domino R5, games, etc….
 Linux is free and easily downloaded from the
internet, or can be purchased at a much lower
cost than Windows software.
Ease of Operation
Corel Linux has an Update wizard
which can install more recent versions
automatically.
Use Corel update to remove
applications that you no longer want to
use.
Reinstall deleted applications at any
time.
Init Runlevels
0 -- Halt level
1 -- Single user mode
2 -- Multiuser mode (with no shared
resources)
3 -- Full Multiuser mode
4 -- Not used
5 -- Full Multiuser mode (with X-based
login screen)
6 -- Reboot
Init Program’s Main Roles
It creates processes, which has the effect
of bringing the system up to the default
run level.
It controls transitions between run
states by re-reading the inittab file.
Inittab File Defines
The system’s default run level
What actions to be taken when the
system enters a new run level
What processes to start, monitor, and
restart if they die
Run Control Scripts
The scripts for starting and stopping
system services are located in the
rcR.d directories, where R is the runlevel.
Files that start with S are used to start
processes.
Files that start with K are used to kill
processes.
Init.d Directory
The start and kill files in the rc#.d
directories are hard linked to scripts in
the init.d directory. This is done to
facilitate booting.
An important advantage of having the
actual run control files in the init.d
directory is that you can start and stop
individual processes from a single
location without changing run levels.

Multitrack
Multitrack is a SVGAlib digital audio editor. It'll soon come out in a 2.0 version. It's too bad it's not X-based.
Another irritating thing is that you must create the WAVE files that you are going to record before you can
record. So, it's a bit clumsy.
For: Very clean UI, very nice functions
Against: It's not X, some irritating things
