Getting started with Linux
============================
UNIX -> Bell LAB (1969)- Dennis Ritchie
-> Based on "C" Language
UNIX Distribution:
------------------
=> IBM - AIX
=> HP - HPUX
=> SUN - SUN Solaris
=> UNIX-BSD
1969 - UNIX was Devloped, Ken Thompson and Dennis Ritchie
1971 - First edition of Unix released 11/03/1971.
1983 - AT&T is splitted -> It can sell software
1983 - FSF - Free Software Foundation
1983 - The GNU project is first announced by Richard Stallman
GNU (GNU Not UNIX) - 1983
A program is free software if the program's users have the four essential freedoms:
===========================================================================
=> The freedom to run the program as you wish, for any purpose (freedom 0).
=> The freedom to study how the program works, and change as you wish (freedom 1).
=> The freedom to redistribute copies so you can help your neighbor (freedom 2).
=> The freedom to distribute copies of your modified versions to others (freedom 3).
By doing this you can give the whole community a chance to benefit from your changes.
1986 - HP-UX 1.0 released.
1987 - Sun introduced
1987 - Minix Released
