Really Fast.......2007-10-09
The book was delivered the second day after booked on the net, and in a fair price.
Operating compatability.......2007-09-15
A well priced product and from its description ideal for lecture purposes.
Unfortunately it does not work using Windows Media Player, Nero Showtime or Open Source media player on my computer using Windows XP.
Amazon returns system worked well with full refund but I would have liked a version that worked.
review on STUDY GUIDE.......2005-10-10
after being utterly discusted with this poor excuse of a study guide, i thought i would read some horrible reviews on the guide to make me feel better. to my dismay, people can't read and they only posted reviews for the text book, which is actually good but those reviews should be posted elsewhere.
You know there is something wrong with this guide when you see them call CH3-CH3 methane (pg 3 not to mention they got linoleic and linolenic mixed up) or on the multiple choice on page 19 has ribosomes as one of the right answers for proteins involved in transcription.
i have not done a lot of the questions in the book and all ready i see errors on every second page. i wonder if i will actually recieve lower grades if i study from this poorly written book.
I love study guides and have used them for stewert's calculus, campbell's biology and bruice's organic chemistry in college. were there some occasional mistakes... yes but overall they were good. this study manual however seems to have been written by a tribe of wild monkeys pounding on a keyboard. Save your 23 dollars
Inferior in every way.......2005-08-18
The Alberts text (Molecular Biology of the Cell, Fourth Edition) is superior to this text in every way. It is clearer, more precise, and contains more information. This one manages to make simple concepts become quite difficult.
Excellent but starting to get outdated.......2005-03-06
Excellent. Hands down the best book out there for cell biology. Gives a thorough look at the exciting unraveling of the cell. Figures are exceptional. However, being now ~3 years old and due to the intense output and growth of scientific literature this book is starting to get outdated. There have been several advances in a number of transport systems (i.e. Nuclear transport and regulation of gene expression). A new edition in the next year or so would hopefully address these issues.

this book should come with its own textbook.......2007-09-25
this book sucks-- plain and simple. Go and get some outlines and another textbook if you want to learn DiffE from this book. Examples are horrible, none of the problems correlate and this book just doesn't explain the in between steps. When i want to learn something, i need to see the complete though process, not spend hours trying to figure out how they got form point a to point b in the example.
Great companion to lectures........2007-04-27
The most important thing to keep in mind would be the intended audience of this book. Specifically, the concepts outlined in this text should complement the content provided by a legitimate math instructors. If I were to use this book to self-teach or something of the sorts, I'm sure I would hate this book as well. Although the examples are sometimes unclear, the summaries of techniques are the most helpful parts in the book. At the end of a section, a blue box outlining the fundamental steps in a process reveals the simplest way to approach any problem. For example, this text's summary of Variation of Parameters pretty much sums up everything about that process in a clear and concise way.
Anyways, it's not as if you have any other choice when the instructor assigns this text as a required material. If looking for a self-teach sort of book, this text is not that great. But if you're looking for a review of ODEs and whatnot, I would recommend this book.
Simply the best undergraduate text extant..........2007-04-18
and I don't "do" hyperbole.
As a math instructor (and math student), I have seen texts on everything from fundamentals of math to real analysis. This book is more practical, clear, and concise than any of them.
Students will not only learn techniques to solve differential equations, they will learn the scope and limitations of each technique. A student who truly reads and absorbs this book will walk away with not only an understanding of but also a healthy skepticism toward mathematical models. The harsh realities of mathematical modeling, such as sensitive dependence on initial conditions, are emphasized rather than downplayed. In the section on motion problems, students are treated to a discussion of how solar system models have evolved. Models must adapt to explain new data. Sometimes a model can be "tweaked" at the expense of simplicity, while some models must be scrapped altogether. Scientific ideas are not gospel, but merely a description of the world as we see it today.
Unfortunately, this text is the ONLY book I have seen which truly addresses the issues described above (and that's very sad because my undergrad degree is in chemistry). Aspiring scientists and engineers need to learn intellectual flexibility as much as they need to learn facts and formulas. This book teaches both.
If the applications in this book were not so overwhelmingly excellent, I would have started this review by exalting the proofs and derivations. They too are unusually well done. The authors do an excellent job of choosing which proofs to include, and they make them as readable as humanly possible. (I hear the bitter chuckles of innumerable math students as I type the previous sentence...)
Yes, learning to read proofs IS hard. But, trust me, this book is where you want to start. First graders think adding and subtracting whole numbers is hard. They're right; for them, it is. But imagine how much harder it would be if first graders had to work with fractions!
To paraphrase Aristotle, "learning is painful". No one can make differential equations easy (why do you think scientists and engineers get paid so well?). However, the authors of this text make it as easy and pleasant as possible.
I suspect that students who disliked this book but were able to "learn" diff. eq. merely learned enough to pass the test. Students who do not take advantage of the learning opportunity provided by this book are doing themselves a serious disservice.
Take home message- buy it and make it the central element in your studies of differential equations. You will be glad you did.
lack of examples and horrible explanations make a ghastly diffE text.......2005-10-13
Because the guy who initiated the project of writing the book is here at Rice, the rest of us are unlucky enough to have to use this book. If your class uses this book, prepare to go to class. All the time. That's because if you fall behind, the book does not do a good job of explaining things to you. Examples are generally vague and only apply to a few types of problems provided at the back of each section. A lot of the time, I'd find myself stumped on a problem, looking back, and realizing there was no example problem for me to get ideas from.
Yes there are lots of problems and that's good, in a way. But what's the point of having all those problems if the book never teaches you how to do them?
Furthermore, it is a poorly written book. Generally, reading through the book is like searching for a needle in a haystack. Literally speaking. You spend all that time figuring out what the authors talk about and once you figure it out, it was not even worth all that time.
So go to class. All the time. If the prof isnt that great, get yourself another workbook. I havent seen Schaum's but I'm pretty sure they'll do a better job on covering the topics than this text does.
Worst book in Undergrad Career.......2005-01-13
tulane uses this book exclusively for diferential equation. This is t quite possible the worst text book i have ever used. They like to say that they don't put as much emphasis on specific solution techniques as they do to solving pratical equations. this means solution methos a briefly mention then sections up section are made of problem you should be able to solve if you were to know the solution methods. some sections don't even over solving differential equations at all.

very good text.......2005-10-18
This text is very detailed and loaded with examples. It is very easy to read.
Practical discussion on a complex organization.......2000-10-07
The book provides practical concepts for healthcare administrators. The extensive use of charts, tables and diagrams has been very helpful in presenting complex concept. Even though many of the concepts presented are not new, the practical examples cited helps to bring out present application of the concept.
While the book has been written in the US setting, I find it applicable to my work in Thailand. I intend to use the book for the administration residency program which we are conducting at our group of hospitals.

Well worth the money........2006-05-21
I own the 4th edition. I had to make a comment after amazon recommended the 5th.
This is a great book. Originally, i was PO'ed at the price. Especially when you get it and its quite thin compared to many texts. I had to get it for APICS.
Once you start reading it you find it cuts through all waste. This is not a padded book. It explains concepts in a brief, direct manner. Most importantly it communicates clearly. Its like a well written executive summary of the field of materials management. There is enough detail for practitioners.
I have almost all texts in the recommended reading of APICS. This is probably my favorite. The utility you will get per unit of time reading this is huge.
Basic Supply Chain.......2006-03-14
This book has an easy written language and is very good for beginners in the Supply Chain Management Area.
Best book to understand manufacturing process.......2006-02-01
This is one of the best books I have come across which explains the basics of Manufacturing.
A good textbook.......2005-11-17
This book covers the basics of material management and goes into some quantitative detail as well. It is very well written and its lucid style is perfect for a beginner to get a grasp on the subject.
The author clearly and logically explains the concepts of production planning, master production schedule, MRP, Production and activity control, purchasing, inventory management, forcasting, demand planning and much more.
The book also has an abundance of examples and exercises for the student to work through. It makes a good read as a beginner's textbook - but it is probably not very useful as a practical guide for the experienced professional.

Easly Understood by Geochemists.......2006-02-20
The "Standard Methods" is very well understood even for those in the non-Chemistry area that deals with environmental chemistry/geochemistry of natural waters. Besides the analytical work, many important aspects related to sampling and data interpretation are there. The 2005 Edition makes these tasks much easier.
Book Description
The Great Bust Ahead is a concise, straight to the point book laying out in stark terms the case for a coming depression of historically unprecedented magnitude. It will be much worse than the 1930s, beginning perhaps as early as 2009-2010, and last up to thirteen years. Centered on hard fact demographics, the book boldly claims that the data presented are so irrefutable, that the outcome predicted by the book is equally as irrefutable. The compelling proof presented accurately accounts for the detailed trend of the economy from 1920 to today (something never before accomplished), and projects out to 2030 in detail. The book is very easy to read and understand, and requires no prior knowledge of economics. Down to earth things the average person can do to prepare for what is coming are covered. A summary of the catastrophic domestic social and international consequences is offered.
2006 Update: In late 2002 when this book was published, in addition to the massive depression beginning towards the end of the decade, it forecast:
1. The economy, as reflected by the DJIA, would resume its upwards march in late 2002 or 2003.
This is exactly what happened.
2. The DJIA would have a snap-back to 13,000 to 14,000 and the FTSE to 6,000 to 7,000 by 2004, but delayed possibly by wars/politics/terrorism/scandals.
This is exactly what has happened. Although still delayed from the full snap-back for the reasons described, the DJIA is now over 12,000 and the FTSE is over 6,000.
3. The inflation adjusted DJIA returns from 2003 to 2012 would average 7% to 8%. So far, with the delayed full snap-back, inflation adjusted DJIA returns have averaged a more modest 4%, as would be expected.
4. Interest rates would increase from 2003 onwards.
This is exactly what has happened.
Customer Reviews:
It is just an indicator!.......2007-09-12
Everyone is forgetting that the book is talking about a correlated indicator for the DJIA. There are many things that drive an economy and make things happen like the weakening dollar, monstrous deficits, the Federal Reserve, cheap credit and the housing market bubble, peak oil, etc. These are some of the things that move the DJIA, NOT just demographics. The fact that the 45-54 age group correlates to the DJIA is very interesting and CAN be used to predict what MAY happen to the DJIA in the long term. Demographics of the 45-54 age groups are a strong force pushing the markets, but not the only thing. Even the author says that some things like "the New Deal, the pill and the NASDAQ" affect the correlation with this indicator. The politicians and Wall Street are not going to lie down and let this monstrous depression happen without a fight. They my not win the War, but where the DJIA goes in the future has not been case in stone. The future highs and lows of the DJIA are still unpredictable.
The book is a high school treatise on this relationship and to the economically ignorant is a real eye opener. Most economists know about this force, but the key is what to do about it and when. The author's advice to get out of the markets by 2010 is silly at best. We are now in September of 2007 and the housing market bubble burst is probably the beginning of the down turn of the markets. Wait until 2010 to protect your assets and you will far less assets to protect. The author's advice to sell your home and rent and plow your money into bonds is simplistic at best. Investing in gold, foreign currencies, TIPS etc. to protect your assets are other stratigies that are not addressed. We are all speeding towards this economic depression, but the answers to when it will happen and what to do about protecting your assets is NOT even close to being addressed by this book. The book is $8.95 and you get what you pay for, "a wakeup call for the economically ignorant". Read the book and move onto a more advanced book for a better in depth discussion on economics and your money like "The Second Great Depression (Paperback) by Warren Brussee (Author)". I do agree that a lot of pain is ahead for the world.
Not Bad But Too Short and Too Extreme.......2007-08-22
Let me start by saying that this is a pretty good book for the price and if you don't know what is going on in the economy. The problem is that the book has very limited data to back up the predictions. If you are going to make huge predictions you had better justify it with a lot of credible data that has been referenced. As well, some of the predictions are just too extreme. However, all of these shortcomings aside, the author provides a nice short treatment on what will most likely occur; just not to the extent he has presented in my opinion. Of course, opinions are like debt in America - everyone has their own!
A much more useful book in my opinion is "Cashing in on the Real Estate Bubble." It not only shows you many different ways to profit from the current bubble collapse, but it also shows a lot of detail about the economy and how to profit from America's overall credit bubble. Cashing in on the Real Estate Bubble
Interesting theory but..........2007-07-09
This book is short and easy to read. The author has an interesting concept that the stock market follows the number of Americans at their peak buying age. His graphs and explanations on modifying factors make everything fit. I agree that some correction of our economy (inflation, recession, or worse) is likely in the future, but I feel other factors (energy issues, our national debt, terrorism, etc.) will come into play that he has not taken into account. I also don't agree with his investment suggestions and feel they may be reckless.
If you're concerned about possible bad times ahead, this is one book that may helpful, but I better liked the reasoning and proposals on what to do in Stephen Leeb's book The Coming Economic Collapse: How You Can Thrive When Oil Costs 200 Dollars a Barrel.
Excellent Read.......2007-05-14
Pros:
1. Brief: to the point, no fluff book(let)
2. Logical: Numbers support theory all along
3. Simple: Easy to understand
4. Value: Could save your shirt
Cons:
1. May sound too negative
2. May not consider all factors into forecasting
Pretty interesting read.......2007-05-12
This book and the argument that it lays out is pretty eye-opening. It shows you, through logical argument, how the demographics of our country will impact our coming future economic health. With these baby-boomers greying and falling from their peak spending years, our country will experience a downshift that will really challenge our concept of prosperity... A must read!
Book Description
sed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox. sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts. This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case. In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).
Customer Reviews:
Are you serious?.......2007-08-23
In a nutshell, if you don't have this book, you are probably not a serious programmer or system administrator.
Both sed and awk have been around for ages, and they are part of the fundamental toolkit of any Unix/Linux professional. Furthermore, there are versions available both for native Windows and for Linux-like environments under Windows (cygwin, MKS, mingw.)
If you are a Perl hacker, you probably use Perl for a lot of the tasks that would otherwise be performed with one of these tools. Nevertheless, they are worth your time.
The best (only?) book to learn these tools from A to Z.......2007-08-02
I had to do some text processing and I wanted to learn sed & awk so I picked this book that is, to my knowledge, the only book completely dedicated to these tools. The chapter on 'advanced' sed programming is very scary because when using 'advanced' sed features, the syntax is cryptic. It is nice to know that these features are there but I want to stay away from them and perhaps use awk or perl for the tasks that would require those 'advanced' features. Still, when you stick with the 'basic' and 'intermediate' sed features, you can do cool things easily in shell scripts.
Overall, the book was not thrilling to read but it does a good job to teach you these text processing tools.
I must be the only one who hates this book!.......2007-07-05
I have looked in this book again and again in an attempt to find out "how do I do xxx with awk or sed?" I just need a quick and dirty script to do something. The way the book is written prevents getting such answers. It is TERRIBLE as a resource for solutions to real problems. Presumably you can "learn sed and awk" from it, but what I want are answers, and this book gets in the way of that. It has literally never helped me solve a problem -- I always end up finding what I want with google somehow. Example: my latest experience was trying to write a script to simply go through a long shell script, and for each line, if it started with "if", "case" or "done", I wanted to prepend "echo line#" (echo the line number) to the line, so it would echo the line number when the script ran. If it had a certain other string in it, I wanted to replace that string with another, and if none, then just preserve the line. Should be pretty simple as a programmer, but I could not get the answer out of this book. It does not mention the FNS variable which allows you to echo the line number, for one thing. Sigh, I could go on... I'm in the minority, but I've made my point. I'm still looking for a good sed/awk reference.
Useful to learn it, not for experienced users, and not a reference book either........2007-07-01
I have a science background and am a regular user of unix systems, although I am not a professional IT'er. Therefore I was already familiar with sed and awk. I was looking for a single book that would give a good overview of all functions on a more-than-beginners-level and at the same time could serve as a reference. Perhaps not as 'the ultimate reference' but good enough for professionals who want to use sed and awk in a pragmatic way. With this I mean: a book you can turn to if you just want to write a little program/script that get's the job done.
This is not that book. I found this book useful in explaining the basics of sed and awk. There is also a quick reference section on both sed and awk. However, my overall observation is that the level of this book is not very advanced and therefore did not do the job for me. I would recommend this book to beginners and not to people who have already used sed and awk themselves. The level is basic, the reference sections are too brief and incomplete to be really 'reference sections'. I am still looking for a real reference book.
Tip: if you want to get started with sed and awk, search the internet for "sed one-liners" and "awk one-liners": these are one-line example 'programs' or commands that most likely will do what you are looking for. And if not, they are helpful to get you going and make some trivial changes so that the program does do what you need. No need for buying a book.
Definitive.......2007-03-30
I've been into Unix since the 80s... Minix on an Atari ST for the nostalgic... including being system admin on various Unix platforms at work (Solaris, HP-UX, DRS-NX, SCO Unix, BSD, etc.) and this has always been the definite work on both SED and AWK and has helped me out with various admin tasks over the years...
Highly recommended and essential for sysadmins

impossible book.......2003-12-03
As a graduate student in accounting, I've found this book to be the most difficult and the most frustrating to read amongst my collection. This book is certainly not helpful to visual learners as there is mostly very dull text explanation of the subject material. Also, the few in-chapter examples worked out are very difficult to decipher and are poorly explained, so you're left on your own to learn how to do the end of chapter problems.
Finally a great book on Advanced Accounting.......2001-06-27
I have never come across a texbook that makes consolidations easy----until now! It seems that most advanced accounting texts are written by Ph.D's to impress other Ph.D's. This one is different. It actually explains in a concise manner all important aspects of advanced accounting in a way that is easy to understand and apply. Unfortunately, it was written in 1995 and obviously doesn't contain some of the more recent exposure drafts on consolidations and derivative accounting for foreign exchange forward contracts.

Customer Reviews:
Excellent Book.......2007-10-02
I used the 3rd Ed. in UC Berkeley's MATH 110: Linear Algebra, then used the 4th while grading homework for the same class the next year. I think the book is fairly comprehensive (though by itself not enough to prepare one for grad school), and very well-written. The exercises at the end of each section span a wide range of difficulty. The book is self-contained, except for a few basic results from the calculus (one has to know the linearity properties of derivatives and definite integrals, i.e. derivative of linear combination is linear combination of derivatives and similarly for integrals), yet does sort of assume prior knowledge of linear algebra. At UC Berkeley students have already taken MATH 54: Linear Algebra & Differential Equations, which includes a brief treatment of vector spaces, linear transformations, eigenvalues, etc. I wouldn't say this book is "not for the faint of heart," as some reviewers put it. I think it's ideally suited--essential, in fact--for entering juniors majoring in the any of the mathematical sciences. If this book is your first exposure to linear algebra, then I highly, HIGHLY recommend chapters 12 and 13 of Calculus, Vol. 1: One-Variable Calculus with an Introduction to Linear Algebra (Second Edition), and chapters 1-5 of Calculus, Vol. 2: Multi-Variable Calculus and Linear Algebra with Applications.
An excellent book, but not for everybody.......2007-04-15
In the great game of textbook-writing, there is always the question of which textbook is "definitive", "comprehensive", yet also "accessible" and a "pleasant read". I will say that no textbook can possible exist that can cater to everybody. Such is the case with Friedberg's "Linear Algebra".
Rather than praising or complaining about the book, I will instead describe exactly how the book is written, and the reader can determine for himself/herself whether this is the book to buy.
The book is written "bottom-up". Instead of introducing a general concept, delving into detail, and then expanding again, in a sort of holistic approach, the book starts very rigorously. He begins with definitions and axioms. This includes definitions for the numbers "0" and "1" and their axiomatic properties.
Using these axioms and definitions, he proves basic theorems. He will then demonstrate several examples that relate to these theorems. In the exercises, he will ask you to prove corollaries to these theorems, or perhaps little theorems, that may help in later proofs. He will also introduce definitions and completely new types of problems in the exercises. Thus, the exercises are NOT supplementary - they are essential to the reading.
Subsequent chapters will repeat the process. He will introduce new definitions, possibly utilizing new knowledge from theorems proven in previous chapters. Then he will introduce and prove several lemmas and theorems. He will introduce a few examples for these theorems. Then exercises. Etc.
Most importantly, the author expects that the student learns through proofs. He expects that, by the very fact that you are able to prove something, you understand the material on a deeper, analytical level. If this is how you operate, this book is for you. If you can't understand a topic unless you see how it can be proven directly from what you already know, then this book is for you. However, it is rare to see concrete examples that are applications. Rather, the author presents everything in an all-encompassing, general manner, and leaves it to you sort out the details and specifics. This can be potentially unhelpful.
Overall, if the proof-based approach is what you're looking for, I haven't seen any book that presents the topic of Linear Algebra in such a concise fashion. Now I leave it to the reader to decide whether this is the book to buy.
Best book on 2nd course in linear algebra.......2006-12-20
If you are taking a second course in Linear Algebra then make sure your instructor use this book. Mine did I am glad she did. Also don't skip chapter 1 and 2 go over all the proofs and as many homework problems to reinforce the concepts. My first instructor didn't cover much from chapter 1 and 2 and I am glad I dropped the course however I hated this book because I didn't know those concepts from the first course in Linear Algebra. Mastering those two will open the way for chapter 5 and 6. We covered a little bit of 7 and I simply now love this book for the wonderful treatment of linear algebra. One of the best book around and after reading this compare any other book on linear algebra and you will know why this book is a bestseller in its category.
Overall Good Book.......2006-11-30
Before I bought this book for my course in linear algebra, I looked through these reviews and saw that this book would be concise and informative (and at times frustrating), so here is what I found.
You are using this for a second course in linear algebra but I have found that it also works for a first course in the subject. In my course we covered 6 of 7 chapters (touched on chap. 7) in a semester and I thought it was a good pace. While this book focuses on proofs, it provides some computational examples and does not assume you have already taken a course in linear algebra. If you want a book focused on applied lin al, look somewhere else, but if you want to know this stuff theoretically, this is a great book.
This book can be challenging at points but if you sit down and think, you will understand because the explanation is generally good. (An exception for me was the section on Dual Spaces). Also it can get annoying that the book does not mark vectors in any way (bold, arrow on top...) so in some places this can be a bit confusing. The only reason I am giving this 4 stars is because the book cuts a few corners like these.
Overall, I would recommend this book for either a real first course or a theoretical second course in linear algebra.
Great Book!.......2006-02-25
This book is great. I used it for a second course in linear algebra. I can really say that I understand the subject now, which I definitely couldn't before. The material is presented in a readable and yet rigorous and abstract fasion. My only problem with this book is that it leaves so many proofs to exercises and doesn't give the answers to most exercises.

Book Description
Shell scripting skills never go out of style. It's the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. Classic Shell Scripting is written to help you reliably navigate these tricky waters. Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them by themselves, and in combination with the other programs. The authors are intimately familiar with the tips and tricks that can be used to create excellent scripts, as well as the traps that can make your best effort a bad shell script. With Classic Shell Scripting you'll avoid hours of wasted effort. You'll learn not only write useful shell scripts, but how to do it properly and portably. The ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Linux systems. Classic Shell Scripting gives you everything you need to master these essential skills.

Excellent book to learn the basics.......2007-03-13
I've scrolled through lots of books, there is so much information out there, but this book has a tendency to keep it simple and to the point. It has good illustrative examples that not only are useful but also serve as a good practice guide.
A good intro on Unix shell scripting and the problems it solves.......2007-02-16
The purpose of this handy little book is to help someone who is working with Unix through the labyrinth of tools available and learn how and when to use them. It is important to note what is mentioned in the preface - "Throughout this book, we use the term Unix to mean not only commercial variants of the original Unix system, such as Solaris, Mac OS X, and HP-UX, but also the freely available workalike systems, such as GNU/Linux and the various BSD systems: BSD/OS, NetBSD, FreeBSD, and OpenBSD." I quote the book because the word "Unix" is about as descriptive as the word "car". The intended audience is anyone who is computer literate, already knows how to program, and is regularly faced with diverse problems in the workplace that must be solved with Unix tools. This book should give you a taste of which tool to turn to and when.
This book can be divided basically into two halves. The first half is a tutorial on writing Unix scripts. The book starts with a brief history of the Unix language and the philosophy behind Unix tools. Slowly, each chapter builds up your skill at script writing. You are shown how to differentiate between shells, how to work with text extensively, how to use loops, pipelines, variables, and decision statements, and how to work with files. There are detailed example scripts at every step along the way. By the end of chapter seven, you should know enough about basic shell scripting to be dangerous.
Starting in chapter 8, you are showed more application-related information. First, Chapter 8 shows and discusses some ready-made scripts for some tasks for which there is no out-of-the-box Unix solution. Some of the handy solutions shown are for path searching and automating software builds. Chapter 9 is a crash course on awk, and is aptly named. It is just enough to be dangerous. You learn how to solve common text processing problems with awk, but you'll need more resources to be really knowledgable. Chapter 10 explains the usage of common commands for listing files, modifying their timestamps, creating temporary files, finding files in a directory hierarchy, applying commands to a list of files, determining the amount of filesystem space used, and comparing files. Next there are two applied chapters showing you how to merge several databases and how to perform spellchecking by using scripting. Chapter 13 changes the subject a bit and talks about the concept of processes in Unix and how you can use their statistics to accomplish a number of monitoring and control tasks. Chapter 14 talks about problems you may run into if you try to take advantage of shell-language extensions, while Chapter 15 addresses the issue of writing secure scripts to the extent it is possible to do so. Writing man pages, and the basics of the Unix filesystem are the subjects of the last two chapters of the book.
I would say it is a good modern introduction to the subject of shell scripting and Unix tools and how to use them. It doesn't dive deeply into any particular topic, but it will get you started by broadly introducing you to the problems most Unix script writers and system admins face regularly and how to get started solving those problems. I highly recommend it for that purpose.
Nice overview of Bourne/sh scripting.......2006-11-17
This book provides a nice overview of the Bourne/sh shell's commands. I wish there were more examples with complete scripts. Korn shell users might want to consider "Korn Shell: Programs for Your Survival at Work" by Larry L. Smith. Bash users might want to consider "Bash Shell: Essential Programs for Your Survival at Work" by Larry L. Smith. Some of the examples in Randal K. Michael's "Mastering UNIX Shell Scripting" are also helpful.
Okay.......2006-03-12
I would say this is a pretty good book that covers it's subject very well, buti didn't use it much because i had also bought Unix in a Nutshell, Fourth Edition, which covered the basics and differences between the shells briefly, which was all i needed at the time. but i looked through this and read some stuff that helped and it is a good book if you plan on doing extended shell scripting. it was just a little more than i actually needed
Practical and useful .......2005-09-20
Great book. The emphasis is nicely split between actually using the shell itself and the whole supporting cast of unix tools (sed, awk, cut, join, sort etc.) The idea of carefully crafting solutions using the unix toolbox mindset is key. I also like the fact he doesn't try to teach to multiple shells, but first tries to emphasize portability by sticking mainly to a POSIX standard, and only later adds info about non standard shell topics. If I could only have one book on shell scripting, this would be it. The best description is 'Practical'.
