A good very basic introduction to command level CICS
580846
This book appears to be targeted to those who can barely spell CICS and have been coding COBOL for no more than a few years.  It has a feel of being very, very basic.  Not quite condescending but they assume you know nothing, which I guess is the safest way to write a book like this.  I only wish they had gotten into a bit more detail about some of the slightly more advanced functions.  My background is in macro level CICS and I wanted to learn how to code the same functions in command level.  Not all I had hoped for was covered in this book.  If you really know nothing about CICS, then this will probably prove a very helpful book.  If you have been programming for years, as I have, and need to finally get up to speed on command level, prepare to slog through a bunch of stuff you already know about programming to get to the few bits and pieces of CICS specific knowledge.

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.

I've been a fan of the Cisco CCNA/CCNP portable command guides since they came out and I was excited to see this format expanding into other areas as well.  The Windows Server 2008 Portable Command Guide is built just like its Cisco brethren including a multitude of commands and good depth on each.

The format of the book is stylized to allow for lots of content and easy classification.  It should be noted that this is not a book to be read through, but more of a reference book to assist you in a time of need where you forget a command/process or can't quite grasp what you need to do and want to browse through something to refocus.

I would recommend this book to any sys admins working with Server 2008 on a daily basis as it's a great resource to have.

The book turns wireless hacking into a childs play for the advanced users who already have the experience as a network administrator. If you are a newbie, please do not be afraid of using Kali Linux. Using this book as a manual and following its helpful screenshots will surely accomplish your task quite easily; there is no doubt about it. Yes, Sir! This book makes Wi-Fi pentesting quite an easy job by making you familiar with the modern attacking techniques. But, don't get me wrong! This is not a definite Bible, but a helpful guide with step-by-step instructions (indeed, you will have to use Google for more details on the topics). In other words, please be aware of the fact that a 100-page book is far too less to provide you with the theoretical background needed to understand how things work behind the machine, but this one starts directly with an in-hand approach. Having said that, you also need some basic knowledge of Linux command line and sys-admin skills in order to avoid unnecessary frustration.
The reason I am giving 4 out of 5 stars to this book is because I would like to see a chapter about how to properly set up and configure a testing environment that could be used as a target for the techniques described in this book

Good introduction to GIT and its command line operations.  Downloadable exercises for each chapter particularly helpful.

Only addition I would like is some supporting information for Windows users.  For example something early in the book explaining how to change the default editor from vi to at least notepad. (config core.editor).

This is an excellent book for an introduction of how computers work. I read it and bought another copy as a gift. I'm not reading another book and perusing A+ certification, and looking back How Computers Work is a simplified version of the certification guide.

Its biggest problem is that it was published in 2007 and has a few outdated pieces of information (does not discuss what is replacing frontside bus, predicts that HD DVD will defeat Blu Ray) and he wastes valuable pages explaining how non-computer related electronics like TIVO and the iPhone work. If you've never moved a mouse before, this book won't redeem you, but you need to know the basic parts of your computer and how they work together, or how your printer or the Internet works, you'll find it helpful.

4.5/5 stars

This book is very well written with awesome commands, most of the commands that you can find in the cisco route book with added extras that can be very helpful when configuring things that you forgot how. Each command comes with an explanation as to why you're typing in that command and the impact that it makes on the equipment. You'll be hard pressed to find all your favorite and most used commands all in one small useful book complete with diagrams and pictures. The only thing to make it better would be to have it do the work all for you.

Clear, concise and to the point examples back up a well thought through and sensibly paced book.
I liked the way that win32 issues were clearly dealt with - no'more trying to work out why your UNIX based examples don't  work.
This book is excellent value for the $$ - you'll easily recoup in  saved time the cover price.

Organized around tactical, actionable CI topics.  Goes into great detail on topics such as continuous database integration, testing, static analysis (which the author calls inspection), and deployment and feedback.  The book has a straightforward conversational style; unlike many texts out there, I didn't have to work hard to understand the message(s).  It is not biased to any one particular implementation language/environment.

This is a very handy compilation of basic concepts.

Bottom line up front:  If you are a programmer or are primarily interested in Linux, you can probably change the rating to "4 stars", simply because this book is oriented towards the Microsoft set, and is primarily focused on the features of IPv6 and networking, with no code samples.

Even so, if you are looking for a volume that covers all of the major aspects of IPv6 down to the packet level, this is a good place to start.  CD-ROM includes PowerPoint slides and an "e-book" (in .chm format, sorry anti-Microsoft folks).

Basic breakdown of each chapter is to introduce a topic in generalities, and delve into specifics, offering syntax examples of commands, etc. in Windows format where appropriate.

Overall, this is a solid book.  Given the shortage of "overview" style IPv6 books as of this writing, this book is a necessity (Microsofty or not) for your bookshelf if you will be implementing IPv6 any any form in the foreseeable future.

The book is well written in unemotional and descriptive style so there's no confusion.
 A good thing about this book is that it is very patient;the author assumes that you have absolutely NO experience in computers.  He is pretty elaborate even covering on how to enter a command in UNIX.  He says it like this:  Press the characters on the keyboard in a sequence that matches the name of the command you want to use and press ENTER button.  NO ambiguity there.
 But the only thing I don't really like about it is the chapter on system administration.  It doesn't quite cover advanced topics such as setting up NFS, WWW servers, etc.. BUT the purpose of the book wasn't to tell you EVERYTHING.  Rather, it is designed to get you comfortable with UNIX so you can advance if you want.  But this book already has plenty of information to start doing some productive work in UNIX.
 Overall, I recommend it if you have absolutely NO experience with UNIX and you just want an easy, no -frills guide.

This book is good as an introduction to Linix administration for readers who are completely new to Linix.  I concur with a number of the readers in that this book does lack depth.  For myself, it was useful in terms of the  breadth of information provided.  If you are completely new to this  operating system, this book suffices as an overview of common  administrative tasks.  You will get a basic feel for what needs to be done,  but you won't learn operating-system specifics for your particular  distribution of Linix.  My recommendation is that if you are new, use this  book as a start.  Identify why you are setting up a Linix server (or  workstation) and then jump to the appropriate chapters on that topic.  The  book is well-organized, so you'll have no problem finding your way around.  When you're ready, buy another book that focuses on what you're interested  in.

The author describes the various admin consoles in simple layman's terms.  She covers advanced topics like Solr installation and high availability configuration for Alfresco.  If you never set up HA before, she covers the various configurations in good detail.  One notable chapter is Maintenance and Troubleshooting - she describes how JMX interface allows you to monitor and make real-time changes to Alfresco without restarting the app server.  This topic is barely covered in other books.  This is good starter book for Alfresco newbies.

Decent little collection of nmap commands, with some explanation on a few:  like -g is shortcut for --source-port and --g is a good one for evading firewalls, or -sl to use an idle zombie especially good to combine with -Pn.  It's an inexpensive 2 hour light-read.  I took notes and ended up with a half page (30 lines) of notes.

Although the information would be a little basic for anyone actively  involved in network security it does provide an accessible introduction to  the major topics for the new user. There were a few errors scattered about  but most were clarified through inspection or a review of other resources  mentioned in the text. Although I would not call it the  "ultimate" guide, I did find it to be a worthwhile text.

While this book - as stated in its title - serves its designated purpose as a "Quick Reference" pretty well, be well aware of its limitations.
If you're not yet familiar with UNIX, make sure to work your way through one of the better introductions to UNIX. My personal favorite is Steven R. Levine's "UNIX for Dummies; despite the somewhat derogatory title of this books series (or maybe because of it), it is an easy read, and provides the UNIX newbie with a solid understanding of the overall concepts of UNIX, as well as the use of the most common commands.
Don't expect too much from "UNIX in a Nutshell". While it comes in handy whenever short term memory proves insufficient to recall certain command options and the likes, this reference only provides a terse abstract for each command.
Even though these abstracts in most cases are a little bit more elaborate than the "usage" section of the man pages, you will still have to check the man pages if you need a more elaborate explanation of the command or its options.
On the other hand, this reference will always be handy when you're working on a system that does not have man pages installed, as well as for quickly looking up other information.
Although this book does not, can not, and does not claim to be a "complete" quick reference, it deserves a place on most system adminstrator's, system programmer's and advanced user's desk.
