What is Linux?

Linux is an UNIX-like operating systemkernel, meaning it only provides the corecomponents of the OS

Linux is free and open source softwarewritten by developers across the world

Linux can be used as a desktop OS, onservers, and Linux even powers Android

Linux distributions (distros) are completeoperating systems created by bundlingLinux with other software

Who develops Linux?

Linus Torvalds (pictured above) started the Linuxproject, and although he has only written 2% of the

code, he has written the most of anyone alone.


The UNIX Philosophy

UNIX-like operating systems have been traditionallywritten by programmers, made for programmers. Thismeans it is easy to programmatically work on data.

1 Write programs which do one thing, and one thing well2 The output of a program should become the input of another

curl http://site/d.img.gz

| zcat

| dd of=/dev/sdb


The UNIX Philosophy



Download a file from a URL and write to terminal

curl http://site/d.img.gz

| zcat

| dd of=/dev/sdb


The UNIX Philosophy



Download a file from a URL while uncompressing it

curl http://site/d.img.gz | zcat

| dd of=/dev/sdb


The UNIX Philosophy



Do all that while writing to a disk

curl http://site/d.img.gz | zcat | dd of=/dev/sdb


Package Management

The Windows Way

Users get software by visiting awebsite and downloading theinstaller programDevelopers have to writeupdate managersDevelopers have to write anuninstaller programDependency resolution is doneby sketchy hacks in theinstaller program

The Linux Way

Distributions include apackage manager, a programwhich is responsible for:

software installationdependency resolutionsoftware updatessoftware removal
