    Abstract: 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.

    Abstract: 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

    Abstract: Over the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don't consider themselves computer gurus. Whether you're using Linux for personal software projects, for a small office or home office (often termed the SOHO environment), to provide services to a small group of colleagues, or to administer a site responsible for millions of email and web connections each day, you need quick access to information on a wide range of tools. This book covers all aspects of administering and making effective use of Linux systems. Among its topics are booting, package management, and revision control. But foremost in Linux in a Nutshell are the utilities and commands that make Linux one of the most powerful and flexible systems available. Now in its fifth edition, Linux in a Nutshell brings users up-to-date with the current state of Linux. Considered by many to be the most complete and authoritative command reference for Linux available, the book covers all substantial user, programming, administration, and networking commands for the most common Linux distributions. Comprehensive but concise, the fifth edition has been updated to cover new features of major Linux distributions. Configuration information for the rapidly growing commercial network services and community update services is one of the subjects covered for the first time. But that's just the beginning. The book covers editors, shells, and LILO and GRUB boot options. There's also coverage of Apache, Samba, Postfix, sendmail, CVS, Subversion, Emacs, vi, sed, gawk, and much more. Everything that system administrators, developers, and power users need to know about Linux is referenced here, and they will turn to this book again and again.
