Shell-Skript-Programmierung ist das mächtige Werkzeug zur vollen Entfaltung der Power von Unix. Shell-Skripten sind unerlässlich für Unix-User und Systemadministratoren. Mit ihnen werden Automatisierungsprozesse in Unix elegant und zeitsparend erstellt. Um Shell-Skripten gut schreiben zu können, braucht man mehr als lediglich das Wissen um die Shell-Sprache. Man muss ebenfalls vertraut sein mit den zahlreichen Unix-Programmen. Das vorliegende Buch lehrt beides: die Shell-Sprache wie auch den geschickten Einsatz und das Zusammenspiel vieler Unix-Werkzeuge. Darüber hinaus wird dem Leser mit Klassischer Shell-Programmierung ein tiefer Einblick in Unix gewährt. Mit diesem Buch lernt der Leser, wie exzellente Skripten erstellt werden und wie Fallen umgangen werden, die Skripten zu schlechten Skripten werden lassen. Damit spart der Leser viele Stunden überflüssiger Arbeit. Sie lernen nicht nur, wie Sie nützliche Shell-Skripten schreiben, sondern auch, wie Sie die Shell schnell, zuverlässig und portabel anpassen, um das Beste aus jedem System herauszuholen. Diese Fertigkeit ist wichtig für jeden, der Unix- oder Linux-Systeme betreibt und wartet. Die wichtigsten Themenbereiche, die in diesem Buch behandelt werden: Einstieg in die Skript-Sprache Arbeit mit Textdaten: Suchen und Ersetzen, Sortieren, Drucken, Werkzeuge Arbeit mit Shell-Variablen Ein- und Ausgabe, Dateien und Befehlsauswertung Erstellung von Produktionsskripten Die Programmiersprache awk Arbeiten mit Dateien: Auflisten, lange Dateilisten, Dateimetadaten, Dateien suchen, Dateien vergleichen Rechtschreibkontrollprogramm aus vorhandenen Unix-Werkzeugen aufbauen Prozesse: erzeugen, auflisten, steuern, löschen, Prozess-Accounting, verzögerte Terminierung Shell-Portabilität und Erweiterung Sichere Shell-Skripten.

AWK is an interpreted programming language that is included in most versions of Unix. The name is derived from the initials of its creators--Alfred Aho, Peter Weinberger, and Brian Kernighan--who developed the language in 1977. The language is particularly designed for filtering and manipulating textual data. In this respect, it is similar to Perl, though Perl is more powerful. There are many variants of AWK, including gawk, which is the GNU version. Effective AWK Programming was published by the Free Software Foundation (FSF) and distributed in electronic form with the GNU AWK source code. It was also published by SSC to help make it more widely available in book form, and is now offered by O'Reilly & Associates. Effective AWK Programming covers every aspect of the AWK 3.0.3 and 3.0.4 language. It offers the most up-to-date coverage of the POSIX standard for AWK available anywhere, and clearly distinguishes standard AWK features from GNU AWK-specific features. The author sheds light on many of the "dark corners" of the language (areas to watch out for when programming), devotes two full chapters to example programs, and includes a summary of how the AWK language evolved.

Many Linux and Unix developers are familiar with the GNU debugger (GBD), the invaluable open source tool for testing, fixing, and retesting software. And since GDB can be ported to Windows, Microsoft developers and others who use this platform can also take advantage of this amazing free software that allows you to see exactly what's going on inside of a program as it's executing. This new pocket guide gives you a convenient quick reference for using the debugger with several different programming languages, including C, C++, Java, Fortran and Assembly.The GNU debugger is the most useful tool during the testing phase of the software development cycle because it helps you catch bugs in the act. You can see what a program was doing at the moment it crashed, and then readily pinpoint and correct problem code. With the GDB Pocket Reference on hand, the process is quick and painless. The book covers the essentials of using GBD is a testing environment, including how to specify a target for debugging and how to make a program stop on specified conditions.This handy guide also provides details on using the debugger to examine the stack, source files and data to find the cause of program failure-and then explains ways to use GBD to make quick changes to the program for further testing and debugging.The ability to spot a bug in real time with GDB can save you hours of frustration, and having a quick way to refer to GBD's essential functions is key to making the process work. Once you get your hands on the GDB Pocket Reference, you'll never let go!
