This manual is the definitive reference for GNU Bash, the standard GNU command-line interpreter.
GNU Bash is a complete implementation of the POSIX.2 shell specification (/bin/sh), with additional features from the C-shell (csh) and Korn shell (ksh). Most Bourne shell scripts can be run by Bash without modification.
GNU Bash is free software, distributed under the terms of the GNU General Public License (GPL). It runs on GNU (GNU/Linux) and Unix systems. Versions are also available for Microsoft Windows.
About the Authors
Chet Ramey and Brian Fox are the original developers of GNU Bash.
This is the complete reference on the Borne again shell (bash).
This book is both a tutorial and a reference on shell scripting with Bash. It assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction. The exercises and heavily-commented examples invite active reader participation. Still, it is a work in progress. The intention is to add much supplementary material in future updates to this document, as it evolves into a comprehensive book that matches or surpasses any of the shell scripting manuals in print.
This book covers 60 core Bash commands you will need as a developer. Each command includes example code and tips for when to use it, follows the 80/20 rule: you'll learn 80% of a topic in around 20% of the time you spend studying it.
This book gives an accessible overview of the role and potential of mathematical optimization in call centers. It deals extensively with all aspects of workforce management, but also with topics such as call routing and the scheduling of multiple channels. It does so without going into the mathematics, but by focusing on understanding its consequences. This way the reader will get familiar with workload forecasting, the Erlang formulas, simulation, and so forth, and learn how to improve call center performance using it.
The book is primarily meant for call center professionals involved in planning and business analytics, but also...
This book is an introduction to inductive logic programming (ILP), a research field at the intersection of machine learning and Logic Programming, which aims at a formal framework as well as practical algorithms for inductively learning relational descriptions in the form of logic programs.
The book extensively covers empirical inductive logic programming, one of the two major subfields of ILP, which has already shown its application potential in the following areas: knowledge acquisition, inductive program synthesis, inductive data engineering, and knowledge discovery in databases.
This is a collection of ideas, strategies, and activities for an introductory creative computing experience using the Scratch programming language. The activities are designed to support familiarity and increasing fluency with computational creativity and computational thinking.

Master the complexities of Linux shell scripting and unlock the power of shell for your enterprise, you'll discover everything you need to know to master shell scripting and make informed choices about the elements you employ.
This book will cover the practical aspects of using and interacting with the Bourne Shell, the root of all shells in use in the Unix world. That includes interacting with the shell on a day-to-day basis for the purposes of operating the computer in normal tasks, as well as grouping together commands in files (scripts) which can be run over and over again. Since it's not practical to talk about the Bourne Shell in complete isolation, this will also mean some short jaunts into the wondrous world of Unix; not far, just enough to understand what is going on and be able to make full use of the shell's very wide capabilities...
You've experienced the shiny, point-and-click surface of your Linux computer—now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell. Along the way you'll learn the timeless skills handed down by generations of gray-bearded, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich...
Some areas are covered in other books, but this one goes into some little-seen side streets and alleyways to show you the shortcuts to more efficient use of the shell. ...The material here is invaluable: you're not going to get it from the manual pages! I strongly recommend it.
- Ernest J.
This is a totally neat idea for a book... the command line gets addictive quickly.

Information modeling is a critical process in content management. This book provides basic concepts of information models and explains how to design database based on data analysis and SQL models. It also provides case studies of database design based on information modeling techniques.
This manual is part of the official reference documentation for PostgreSQL 9.0. It describes all the SQL commands available in PostgreSQL. There are over 140 commands from ABORT to VALUES each with a full usage synopsis, description, annotated parameter list and examples. Important commands such as SELECT and GRANT receive extended coverage. The associated client and server command-line tools like psql, pg_dump and pg_restore are also documented. This volume is part of a set. The separate Volume 1A "The SQL Language" (ISBN 978-1-906966-04-1) documents the SQL language syntax, functions and datatypes as implemented by PostgreSQL...
This manual is part of the official reference documentation for PostgreSQL 9.0. It describes the SQL language specification as implemented by PostgreSQL, including syntax, data types, functions and operators, indexes and transactions.
The new XML datatypes and full-text index support of PostgreSQL 9 are also fully documented. This volume is part of a set. The separate Volume 1B: SQL Command Reference (ISBN 978-1-906966-05-8) contains the documentation for every PostgreSQL command from ABORT to VALUES. PostgreSQL client and server command-line tools are also documented in Volume 1B.
Windows Azure SQL Reporting provides a flexible platform for managing and viewing reports. Its cloud-based architecture means that its services are instantly scalable for any number of users - adding and removing servers through Windows Azure is significantly simpler than managing on-site servers - and maintenance costs are kept to a minimum.

This book uses a simple step by step approach to explain the essential relational database design modelling techniques, and shows how Oracle SQL can be used to implement a database. There are numerous practical exercises with feedback.
Key topics include conceptual modelling using the crow's feet notation and the Unified Modelling Language (UML), logical and physical modelling, normalisation, the structured query language (SQL) and simple application development using APEX forms and reports.

SQL: A Comparative Survey is a companion to Hugh Darwen's An Introduction to Relational Database Theory, best studied in parallel with that text. Closely following the structure of the theory book, it shows how the examples in that book can be expressed in SQL. SQL's many deviations from relational database theory are thus exposed and their consequences discussed. Drawing on the author's long experience as a member of the committee responsible for production of the ISO SQL standard, the book includes copious Historical Notes showing how SQL has evolved from its very beginnings in the 1970s.
Whether you're a database designer, programmer, analyst, or manager, you've probably encountered some of the challenges-and experienced some of the frustrations-associated with time-varying data. Where do you turn to fix the problem and see that it doesn't happen again? In Developing Time-Oriented Database Applications in SQL, a leading SQL researcher teaches you effective techniques for designing and building database applications that must integrate past and current data. Written to meet a pervasive, enduring need, this book will be indispensible if you happen to be part of the flurry of activity leading up to Y2K.
