sed & awk: UNIX Power Tools

by Arnold Robbins Dale Dougherty

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. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts.This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case.In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).

sendmail 8.13 Companion

by Bryan Costales Claus Assmann George Jansen Gregory Shapiro

If you had a list of the words used to describe sendmail, they'd probably include reliable, flexible, configurable, complex, monolithic, and daunting. But you're not likely to find the word easy. Even seasoned sendmail pros are sometimes frustrated by the intricacies of sendmail's configuration files. With a little determination and the help of a good reference book, like sendmail , Third Edition, you can master this demanding program. But when there's a significant point release, like sendmail V8.13, where do you turn? An excellent companion to our popular sendmail , Third Edition, the sendmail 8.13 Companion provides a timely way to document the improvements in V8.13 in parallel with its release. The book highlights the important changes in the latest update to sendmail, pointing out not just what is handy or nice to have, but what's critical in getting the best behavior from sendmail. This is especially important now that spam is on the rise, and because mobile technology requires roving laptops to use encrypted connections. Not surprisingly, many of the changes and additions to V8.13 have been driven by the ongoing fight against spam. Anyone concerned about spam--and who isn't?--will benefit greatly by upgrading to V8.13 sendmail. Among its many enhancements, V8.13 includes new routines that support the SPF sending site authentication standard (in the Milter library), simultaneous connection control, high connection rate control, and finer tuning of SASL parameters. The additions to the Milter library, alone, make upgrading worthwhile, but sendmail's connection control makes it a no-brainer. The key to understanding them is the sendmail 8.13 Companion . The book is divided into twenty-five chapters that parallel the chapters in the third edition of the sendmail book. For instance, if you're interested in Options configuration (Chapter 24 in sendmail), you'll turn to Chapter 24 in your companion volume to find out what's new in V8.13. For a simple dot release (8.12 to 8.13), V8.13 sendmail has added more features, options, and fundamental changes than any other single dot release has included. If you need to set up or manage sendmail, you'll want this companion volume close at hand. Even if you aren't ready to upgrade to V8.13, you'll find the key to understanding them is the sendmail 8.13 Companion a useful guide to understanding and staying current with the latest changes in sendmail.

sendmail Cookbook: Administering, Securing & Spam-Fighting

by Craig Hunt

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology.Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem.Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances.The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:Delivering and forwarding mailRelayingMasqueradingRouting mailControlling spamStrong authenticationSecuring the mail transportManaging the queueSecuring sendmailsendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread.
