| Dear Linux/UNIX Experts,
A term "Binary" always hear from UNIX experts. Somebody said "UNIX is binary....babababababa....."
What means of "Binary" in UNIX/Linux?
Thanks!

| Everything's a 0 or 1. | |
| Ian Poon 2002-12-19, 10:22 pm |
| I think they are not mentioned that. I know 0's and 1's are the format of binary file. | |
| ccieToBe 2002-12-19, 11:03 pm |
| I don't understand the question then. | |
| Boulware5 2002-12-19, 11:21 pm |
| Binary file is one that is already compiled. That maybe what you looking for? | |

A program. Something that has been compiled. | |
| Ian Poon 2002-12-20, 1:13 pm |
| I think that is the answer. Why the UNIX/LINUX experts always saying that the Binary files are better than RPMs?
Thanks again! | |
| Mr. Linux Guy 2002-12-20, 1:28 pm |
| Probably what they are talking about is tar'd files. When you get a package in Linux, it can come in several formats. It could come as a package with a name like foo.tar.gz or like bat.i386.rpm or beer.deb or something. The first one you simply gunzip, untar and then you can either use the install script (if it has one) or just compile it and leave it in its own directory (I usually prefer this method). RPM's can contain binary or source data, but an rpm package updates the rpm database that tells you what is installed and gives you an easy interface to uninstall or upgrade it. The Debian package system uses a similar concept to rpms but it is even slicker. Most modern Linux variants use the RPM package manager, and generally I suggest you stick to this, as your system can get kind of messy if you install everything using the source files since you can never tell what is installed on your machine without looking for the individual files and of course upgrading is harder. | |

| Thanks! Understand. I have interested to take a Linux exam. Which one your prefer?Which one can get best valued in market?
(Linux+/RHCE/SAIR Linux/LPI)

Ian | |

| The Debian package management system I think is the best, but the RPMs are by far the most popular. As for certifications, nothing comes close to the RHCE, both in difficulty or in worth. Linux+ is the easiest, LPI sort of in between the two. SAIR and LPI are about the same. | |
| Ian Poon 2002-12-23, 12:27 pm |
| Thanks Mr. Linux Guy! | |
| Mr. Linux Guy 2002-12-23, 12:27 pm |
| My pleasure. | |
| Ian Poon 2002-12-23, 12:42 pm |
| Hi Mr. Linux Guy,
I would like to study the LPI after your analysis.
There are too many resources to prepare the LPI. Would you prefer 2 for me? (Books or Websites)
Thanks.
Ian | |
| Mr. Linux Guy 2002-12-23, 2:14 pm |
| I used O'Reilley's "LPI In A Nutshell". I thought it was great. A very good, but dense little book. | |

| Ian Poon 2002-12-23, 8:13 pm |
| Many experts suggested using LPI in a nutshell to prepare the LPI exam.  I have read it in the bookstore. Lot of commands on the book but not many examples.  Any others?
Thanks!

| Mr. Linux Guy 2002-12-25, 5:45 am |
| Well, like I said, it is a dense book. There is probably an LPI Bible out now, you may want to check it out (and check the reviews at Amazon.com as well). But there are benefits to the minmalist approach taken by the LPI In A Nutshell book -- for one thing the lack of examples, means that youare forced to actully try what is mentioned in the book. It is not merelya "reading book", but one that is sort of designed as a supplement to hacking around with your Linux distro. If this approach os followed, it may well result in a much higher level of skill than a more "take-you-by-the-hand" approach. | |

| ya... but isn't he a new user? why use a cert book to learn linux...
cert books have one goal, to address the exam objective so you can pass and get some letters... not to teach you how to use it...
get one of the general linux book and follow the exercises so you can actually work with linux... then worry about getting certified... certification is to prove you know the stuff, not a basis to learn the stuff.
anyway... RH linux bible are pretty good learning book... and will supplement the objectives in the lpi, so will RH linux: networking and system administration...
when u use the nutshell books to address any particular objective... you should use that as a basis to understand the coverage and depth, then either use the web or the networking/sys admin book or other books to get pratical exercise/view/application of those that are addressed.
for example, nutshell will talk about inetd... you look up inetd/xinetd etc in the other book, 2 or more coverage of the same objective... a learning and a exam book. win win.
edit:
just to reinfoce: I looked over my lpi nutshell...
the chapters are totally break down for the exam... not to teach you linux, not to get linux install and get you working on linux...
for example,
chap 1 is command
installation is 1st chapter of 102. which with the new organization of objectives is now 101... but still.
and even in that chapter, it is not aim to get it install on your system but to address the exam... Ian Poon, go buy something else, go through those other books so you can get it install, comfortable with CLI, comforatble with X even if you just click click click to install... then worry about LPI which even tho is not hard, it is still not entry level... you are getting ahead of yourself.
edit 2: heh... on reread you are talking about the same thing generally... so heh... duh and also, you have to understand the position of the exam. I think it is for ppl with couple months of experience. so it is not interested in guiding you through install, or other basic task involved in using linux as a user, but for admin who has certain familiarity with the OS and understand its role in the enterprise... then apply that to the exam. It provide a more indept discussion/understanding of why something is this way, why and how it is done... at the core, for the task you may already be familiar with because the senior tell you to do this and that every day etc... | |

| I agree, a more comprehensive and detaield book would be better to start with. The LPI In A Nutshell does have the advantage of practically requiring you to try a lot of the things in the book so that you can cement in your mind what theyare talking about but it would be a tall order for a total newbie. | |
| Ian Poon 2002-12-26, 8:55 pm |
| Dear Experts,
I understand. I will buy the LPI Bible and Nutshell. I have seen the LPI Bible in bookstore, it seems more comfortable to my standard. To achieve the LPI cert, I should have a Nutshell Book for your opinions.
Thanks for your kindly help!
Happy New Year!
Regards,
Ian | |

I also think that this is a very beneficial approach, especially with Linux which truly requires a more in depth understanding of the OS almost at the bit level... | |

| Hi Freak,
I will have the CIW-A Exam on 3rd Jan,2003. After that I will prepare the MCSA by using your study guide. Ha! Ha! I look forward to your MCDBA guide.
Regards,
Ian | |

| that's if I ever write it I would make an awful DBA, i have to admit. Now if someone is interested in writing it for www.MCSEFreakPress.com let me know!
I am simply not good enough at SQL to start that project. | |

Aw, c'mon, SQL is easy! | |

| not for this French bloke it ain't For some darn reason, databases are not my cup of tea. It must have something to do with the fact that I really hate dealing with them... The MCDBA is a cert I probably will never pursue. | |

You're not the only one. I've been trying to tie together qmail and mysql for the last few days w/o much sucess | |
| freak 2002-12-27, 12:53 pm |
| don't get me started with qmail. One of the most painful experiences in my life
That's probably where I got the idea for www.LinuxHell.com from in the first place! | |
| ccieToBe 2002-12-27, 1:12 pm |
| Who won in the end? You or qmail? | |
|
| I did, with a lot of help  Heck, I think both QMAIL and I lost, and my buddy Chris won! | |

I'm not sure. I was in a hury to get the mail server setup, so I ended up going with postfix/qpopper. That was too easy - it didn't even take an hour to set those up for the first time |
