<li>Issue the following command: <code>'''hostname f19host'''</code></li>
<li>Re-issue the <code>hostname</code> command (or open a new terminal). What happened?</li>
<li>Note: simply using the hostname command to set the hostname only works during the current running session. In order to permanently (persistently) set the hostname, issue the following command as root user: <br /><code>'''hostnamectl set-hostname f19host'''</code>
<li>Reboot, notice that the hostname has been reset to the original. The hostname command doesn't result in a permanent change. To make a permanent change to the hostname edit the /etc/hostname file.</li>
<li>To find out the kernel version of your GNU/Linux workstation and the date it was created, enter the command: <code>'''uname -rv'''</code></li>
