Command Line and Shell Scripting Techniques begins by taking you
through the basics of the shell and command-line utilities. You'll
start by exploring shell commands for file, directory, service,
package, and process management. Next, you'll learn about
networking - network, firewall and DNS client configuration, ssh,
scp, rsync, and vsftpd, as well as some network troubleshooting
tools. You'll also focus on using the command line to find and
manipulate text content, via commands such as cut, egrep, and sed.
As you progress, you'll learn how to use shell scripting. You'll
understand the basics - input and output, along with various
programming concepts such as loops, variables, arguments,
functions, and arrays. Later, you'll learn about shell script
interaction and troubleshooting, before covering a wide range of
examples of complete shell scripts, varying from network and
firewall configuration, through to backup and concepts for creating
live environments. This includes examples of performing scripted
virtual machine installation and administration, LAMP (Linux,
Apache, MySQL, PHP) stack provisioning and bulk user creation for
testing environments. By the end of this Linux book, you'll have
gained the knowledge and confidence you need to use shell and
command-line scripts. What you will learn Get an introduction to
