Book Description

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

Book Description

Perl is the perfect language for achieving Automation in Windows because it combines a painless Visual Basic style of coding with Perl’s strength as a scripting language for process communications. The new multitasking and networking approaches with 32-bit Windows require a radical departure from previous programming techniques. This book, dedicated to the use of Perl as a language to automate 32-bit Windows, shows how to control many Win32 systems processes without immediate user interaction.

The author explains how to use Perl scripts to automate tasks such as processing complex documents and customizing interactions by making a program look different to different users. Also provided are Perl scripts that will permit network administrators to automate tedious Windows maintenance tasks that range from automating backups to running a Windows system remotely from the Web.

Review
Written for those with some previous knowledge of Perl, Scott McMahan’s Automating Windows with Perl brings the spirit of Perl to Windows along with several handy sample scripts that can simplify the life of any administrator or advanced programmer. Download Now »
