<li><code>make</code></li>
<li>Did the command work? Why? Use the "<code>yum" </code> command to install the package '''gcc'''. What do you think the package ''gcc '' does?</li>

<li>Reissue the <code>make</code> command. Where you successful? What does <code>make</code> do?</li> <li>Issue the command as root: <code>yum list ncurses</code>. What do you see? Issue the command at root: <code>yum search ncurses</code>. What do you observe?</li> <li>In this case, you need to install the ncurses development libraries as well.

</ol>
</li>
<li>Note the difference in output between centos2 and centos3.</li>
<li>You can use the <code>init </code> command to change the current runlevel. See a list of runlevels [https://www.centos.org/docs/5/html/5.2/Installation_Guide/s2-init-boot-shutdown-rl.html here]. Change Use the <code>man</code> command to learn how to use the <code></code>init command. Use this command to change the current runlevel in centos2 to 3. What happened?
