[nagal@xxxxxxxxxx (Dr. Gigels)]

Tva e interesno dobre e chovek da se zamisli kogato se naricha
HACKER ili pak neshto poveche. Govorim za UNIX/LINUX :)
Tva e neshto kato SOVA-5 KADE SME NIE? 
Ha da vidim sega koi kade e :)

What is a Unix Guru?

People who come into contact with the UNIX system are often told: ``If you
have trouble, see so-and-so, he's a guru'', or ``Bob there is a real hacker.''
Often, they are baffled by these appelations, and do not pursue the matter
further.  What is a Unix Hacker?  How does he differ from a Guru?  To
answer these and other questions, I present a draft of the Unix Hierarchy:

BEGINNER
  insecure with the concept of a terminal
  has yet to learn the basics of |vi|
  hasn't figured out yet how to get a directory
  still has trouble with typing <RETURN> at the end of each line

NOVICE
  knows that ls will produce a directory
  uses the editor, but calls it `vye'
  has heard of C but never used it
  has had his first bad experience with rm
  is wondering how to read his mail
  is wondering why the person next to him seem to like Unix so much

USER
  uses vi and nroff, but inexpertly
  has heard of regular-expression but never seen one
  uses egrep to search for fixed strings
  has figured out that - precedes options
  is wondering how to move a directory
  has attempted to write a C program and decided to stick with Pascal
  thinks that dbx is a brand of stereo component
  knows how to read his mail and wonders how to read news

KNOWLEDGEABLE USER
  uses nroff without trouble, and is beginning to learn tbl and eqn
  thinks that fgrep is `fast grep'
  has figured out that mv will move directories
  has learned that learn doesn't help
  someone has shown him how to write C programs
  once used sed to do some text substitution
  has seen dbx used but doesn't use it himself
  thinks that make is for wimps

EXPERT
  uses sed when necessary
  uses macros in vi, uses ex when necessary
  posts news at every possible opportunity
  writes csh scripts occasionally
  writes C programs with vi and compiles them with cc
  has figured out what && and || are for
  thinks that human history started with !h

HACKER
  uses sed and awk with comfort
  uses undocumented features of vi
  writes C code with cat > and compiles with !cc
  use adb because he doesn't trust source debuggers
  can answer questions about the user environment
  writes his own nroff macros to supplement standard ones
  writes scripts for Bourne shell

GURU
  uses m4 and lex with comfort
  writes assembly code with cat >
  uses adb on the kernel while the system is loaded
  customizes utilities by patching the source
  reads device driver source with his breakfast
  can answer any Unix question after a little thought
  uses make for anything requiring two or more distinct commands to achieve
  has learned how to breach security, but no longer needs to try

WIZARD
  writes device drivers with cat >
  fixes bugs by patching the binaries
  can answer any question before you ask
  writes his own troff macro packages
  is on a first-name basis with Dennis, Bill and Ken
