A BEGINNERS GUIDE TO HACKING UNIX

   IN THE FOLLOWING FILE, ALL REFERENCES  MADE TO THE NAME UNIX, MAY ALSO BE  SUBSTITUTED TO THE XENIX OPERATING  SYSTEM.    BRIEF HISTORY:  BACK IN THE EARLY  SIXTIES, DURING THE DEVELOPMENT OF  THIRD GENERATION COMPUTERS AT MIT,  A GROUP OF PROGRAMMERS STUDYING THE  POTENTIAL OF COMPUTERS, DISCOVERED  THEIR ABILITY OF PERFORMING TWO OR  MORE TASKS SIMULTANEOUSLY.  BELL  LABS, TAKING NOTICE OF THIS DISCOVERY,  PROVIDED FUNDS FOR THEIR DEVELOPMENTAL  SCIENTISTS TO INVESTIGATE INTO THIS  NEW FRONTIER.  AFTER ABOUT 2 YEARS OF  DEVELOPMENTAL RESEARCH, THEY PRODUCED  AN OPERATING SYSTEM THEY CANLMD "UNIX".    SIXTIES TO CURRENT:  DURING THIS TIME  BELL SYSTEMS INSTALLED THE UNIX SYSTEM  TO PROVIDE THEIR COMPUTER OPERATORS  WITH THE ABILITY TO MULTITASK SO THAT  THEY COULD BECOME MORE PRODUCTIVE,  AND EFFICIENT.  ONE OF THE SYSTEMS THEY PUT ON THE UNIX SYSTEM WAS CALLED  "ELMOS". THROUGH ELMOS MANY TASKS (I.E. BILLING,AND INSTALLATION RECORDS) COULD  BE DONE BY MANY PEOPLE USING THE SAME  MAINFRAME.    NOTE: COSMOS IS ACCESSED THROUGH THE  ELMOS SYSTEM.    CURRENT:  TODAY, WITH THE DEVELOPMENT  OF MICRO COMPUTERS, SUCH MULTITASKING  CAN BE ACHIEVED BY A SCALED DOWN  VERSION OF UNIX (BUT JUST AS  POWERFUL).  MICROSOFT,SEEING THIS  DEVELOPMENT, OPTED TO DEVELOP THEIR OWN  UNIX LIKE SYSTEM FOR THE IBM LINE OF  PC/XT'S.  THEIR RESULT THEY CALLED  XENIX (PRONOUNCED ZEE-NICKS).  BOTH  UNIX AND XENIX CAN BE EASILY INSTALLED
ON IBM PC'S AND OFFER THE SAME FUNCTION
(JUST 2 DIFFERENT VENDORS).

NOTE: DUE TO THE MANY DIFFERENT
VERSIONS OF UNIX (BERKLEY UNIX,
BELL SYSTEM III, AND SYSTEM V
THE MOST POPULAR) MANY COMMANDS
FOLLOWING MAY/MAY NOT WORK. I HAVE
WRITTEN THEM IN SYSTEM V ROUTINES.
UNIX/XENIX OPERATING SYSTEMS WILL
BE CONSIDERED IDENTICAL SYSTEMS BELOW.

HOW TO TELL IF/IF NOT YOU ARE ON A
UNIX SYSTEM:  UNIX SYSTEMS ARE QUITE
COMMON SYSTEMS ACROSS THE COUNTRY.
THEIR SECURITY APPEARS AS SUCH:

LOGIN;     (OR LOGIN;)
PASSWORD:

WHEN HACKING ON A UNIX SYSTEM IT IS
BEST TO USE LOWERCASE BECAUSE THE UNIX
SYSTEM COMMANDS ARE ALL DONE IN LOWER-
CASE.
LOGIN; IS A 1-8 CHARACTER FIELD. IT IS
USUALLY THE NAME (I.E. JOE OR FRED)
OF THE USER, OR INITIALS (I.E. J.JONES
OR F.WILSON).  HINTS FOR LOGIN NAMES
CAN BE FOUND TRASHING THE LOCATION OF
THE DIAL-UP (USE YOUR CN/A TO FIND
WHERE THE COMPUTER IS).
PASSWORD: IS A 1-8 CHARACTER PASSWORD
ASSIGNED BY THE SYSOP OR CHOSEN BY THE
USER.
