grep kurz & gut ist die erste deutschsprachige Befehlsreferenz zu grep, dem mächtigen Such- und Filterungswerkzeug unter Unix. Jeder, der sich ausführlich zu den Möglichkeiten, die in grep stecken, informieren möchte, ist mit diesem Buch bestens bedient. Er erfährt, wie viele alltägliche Aufgaben mit grep ausgeführt werden können, von der Mail-Filterung über geschicktes Log-Management bis hin zur Malware-Analyse. Der Befehl grep stellt viele verschiedene Möglichkeiten bereit, Textstrings in einer Datei oder einem Ausgabestream zu finden. Diese Flexibilität macht grep zu einem mächtigen Tool, um das Vorhandensein von Informationen in Dateien zu ermitteln. Im Allgemeinen ist der Befehl grep nur dafür gedacht, Textausgaben oder Textdateien zu durchsuchen. Sie können auch Binärdateien (oder andere Nicht-Textdateien) durchsuchen, aber das Tool ist in dem Fall eingeschränkt. Tricks zum Durchsuchen von Binärdateien mit grep (also die Verwendung von String-Befehlen) werden ebenso in grep kurz & gut aufgezeigt. Sollte der Leser bereits mit der Arbeit mit grep vertraut sein, hilft ihm grep kurz & gut dabei, seine Kenntnisse aufzufrischen und mit grep besonders effizient zu arbeiten. Für grep-Einsteiger ist das vorliegende Buch eine hervorragende Möglichkeit, grep von Grund auf zu lernen und klug anzuwenden.

This book is an exploration of Shell programming, also referred to as Bash Scripting. It begins by guiding you on how to automate the various tasks in UNIX by using the Shell scripts. The book also guides you on the effective steps on how to write the Shell scripts. In UNIX, we should come up with an effective mechanism for management of file systems and software packages. This book guides you on the effective way to do this in Shell. You are also guided on how to use the various UNIX editors such as the Vim editor, nano, and GNOME. You will learn how to use the various shortcuts provided by these text editors, as well as how to navigate within your file opened in the text editor. Structured commands, which are very common in Shell, are discussed in detail. You will learn how to use such statements for decision-making as well as for looping through your program. You are also guided on how to manipulate your text, as well as how to use regular expressions. In some programs, it is good for you to implement a mechanism for accepting user input and then making a decision based on that input. This book clearly guides you on how to do this in Bash scripting. Command line arguments have also been explored in detail. The following topics are discussed in this book: - Automate Tasks with Simple Script Utilities - Creating Shell Scripts - Manage Filesystems and Software Packages - Work with nano, KDE, and GNOME editors - Structured Commands, Text Manipulation, and Regular Expressions - Keyboard Input - Command Line Arguments

Werde ein Linux-Ninja mit Command Line Kung Fu! Denkst du auch, dass du dich monatelang in einem Keller einschließen musst, um kryptische man-pages zu lesen, damit du Ninja-artige Kommandozeilen-Skills bekommst? In Wirklichkeit könntest du dir schon eine Menge Zeit und Frust ersparen, wenn du einfach nur jemanden hättest, der dir seine Tipps, Tricks und Tools zeigt. Was wäre, wenn du einem guten Freund über die Schulter schauen könntest, der nebenher zufällig ein Kommandozeilen-Guru ist? Wenn er dir nicht nur die Befehle zeigt, die er verwendet, sondern auch warum er sie verwendet und wie sie genau funktionieren? Und was wäre, wenn dieser Freund sich die Zeit nehmen würde, all das aufzuschreiben, damit du es nachlesen kannst? Wann immer du willst? Tatsächlich gibt es diesen Freund, und er hat genau das getan. Command Line Kung Fu ist vollgepackt mit dutzenden Tipps und über 100 Beispielen aus dem echten Leben.

View: 619

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 heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book's short, easily-digestible chapters, you'll learn how to: –Create and delete files, directories, and symlinks –Administer your system, including networking, package installation, and process management –Use standard input and output, redirection, and pipelines –Edit files with Vi, the world’s most popular text editor –Write shell scripts to automate common or boring tasks –Slice and dice text files with cut, paste, grep, patch, and sed Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

Programmieren mit Perl ist die Übersetzung der 2. Auflage von Programming Perl, der anerkannten Perl-Bibel. Perl selbst ist die erste von Larry Wall geschaffene Legende, dieses Buch (überall liebevoll nur das "Kamel-Buch" genannt) ist die zweite. Gemeinsam mit anderen Perl-Experten lüftet Wall die vielen neuen Geheimnisse der Version 5 von Perl, liefert dabei gleichzeitig aber auch neue Einsichten in die alten und erprobten Features. Perl ist zur ungekrönten Königin der Programmiersprachen herangewachsen und wird zunehmend als die nützlichste Sprache angesehen, wenn es darum geht, eine Vielzahl von Aufgaben über viele Plattformen hinweg und so portabel wie möglich zu erledigen. Nicht mehr zufrieden damit, nur die Unix-Umgebung zu dominieren, zog Perl aus, nun auch noch die Web- Programmierung zu beherrschen. Programmieren mit Perl enthält unter anderem: Eine ausführliche Einführung in die Sprache und ihre Syntax; eine vollständige Referenz aller Perl-Funktionen, Perl-Operationen und Standard-Bibliotheksmodule; eine Erläuterung der Perl-Referenzen und komplexen Datenstrukturen; eine detaillierte Darstellung der objektorientierten Eigenschaften von Perl; weiterführende Themen wie Effizienz, Debugging, Aufrufoptionen, Sicherheit von Programmen, Interprozesskommunikation, Autoloading und vieles mehr.
