Der Zeichenstrom-Editor sed und die Programmiersprache awk sind zwei klassische Unix-Tools zur Bearbeitung von Textdateien. Ihre Fähigkeiten zur Mustererkennung mit regulären Ausdrücken ermöglichen es Programmierern und Systemadministratoren, Editieraufgaben für eine oder mehrere Dateien zu automatisieren. Wiederkehrende Abläufe und Konvertierungen können mit sed und awk so einfacher und schneller erledigt werden. sed & awk – kurz & gut ist eine kompakte Referenz zu sed, awk und zur Mustererkennung mit regulären Ausdrücken. Die zweite Auflage geht darüber hinaus auf die Neuerungen in...

For people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs. The sed & awk Pocket Reference is a companion volume to sed & awk and Unix in a Nutshell. This small book is a handy reference guide to the information the larger volumes, presenting a concise summary of regular expressions and pattern matching,...

sed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox. sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found....

For people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs. The sed & awk Pocket Reference is a companion volume to sed & awk, Second Edition, Unix in a Nutshell, Third Edition, and Effective awk Programming, Third Edition. This new edition has expanded coverage of gawk (GNU awk), and includes sections on: An...

Effective awk Programming,3rd Edition, focuses entirely on awk, exploring it in the greatest depth of the three awk titles we carry. It's an excellent companion piece to the more broadly focused second edition. This book provides complete coverage of the gawk 3.1 language as well as the most up-to-date coverage of the POSIX standard for awk available anywhere. Author Arnold Robbins clearly distinguishes standard awk features from GNU awk(gawk)-specific features, shines light into many of the "dark corners" of the language (areas to watch out for when programming), and devotes two full...
