In this tutorial we are working with our openSUSE 11.4 Linux host and using the command line to manage Linux. We will learn how to use tab completion to help us change directories, optimizing the use of cd – to move to our previous working directory. Using the command ip we will display our IP Address, route table and arp cache. We will then move into configuring the network from the command line using the files in/etc/sysconfig/network. With the configuration set it will me made current by starting and stopping the interface with ifup and ifdown. With so much use on the command line we will look at using ctrl + r with the history to search for previous used commands in BASH.
