To mitigate these problems, Linux provides several tools and features, including <code>nice</code>, <code>ionice</code>, and <code>cgroups</code>. In this article, we&rsquo;ll explore how to use these tools to manage and tame rogue processes.</p> <h2 id="understanding-nice">Understanding nice</h2> <p>The <code>nice</code> command is used to set the priority of a process. By default, Linux assigns a nice value of 0 to all processes. The nice value ranges from -20 (highest priority) to 19 (lowest priority). To adjust the nice value of a process, you can use the <code>nice</code> command followed by the nice value and the command you want to execute. For example:</p>
