Linux Command Line and Shell Scripting Bible, Seco

The Linux Command Line and Shell Scripting Bible shows how to use the Linux shell command line to directly interface with the Linux system. The book covers several popular shells used on Linux platforms, such as bash, ash, tcsh, ksh, korn, and the zsh shell. Within each shell the book discusses the commands available, and demonstrates how to use these commands to create scripts that can automate common functions and reports. The book also demonstrates practical applications for shell scripts, such as using databases, retrieving information from web sites, and sending automated reports via e-mail. All Linux system administrators should know how to program shell scripts to monitor system resources and perform common administration tasks, such as remove old files. Knowing how to write shell scripts is a crucial skill that a Linux system administrator should know, and that the Linux home enthusiast can easily learn. Existing books on this topic cover either shell scripting basics, or provide advanced applications that are hard for the novice to follow. This book demonstrates basic shell scripting in several Linux shell environments, then guides the reader with advanced projects for using shell scripts in real-world applications.
