They are crucial because they let the operating system, applications, and scripts know about elements such as :</p> <ul> <li>Where programs are location; _via _<code>PATH</code>.</li> <li>Your user/currently logged-in directory; <code>HOME</code>.</li> <li>Language or locale settings.</li> <li>System-wide or app-specific configurations.</li> </ul> <p><em>In simple terms, <strong>environment variables</strong> are a foundational way that Linux customizes, configues, and manages the actions of programs and users through simple &ldquo;key=value&rdquo; pairs.</em></p>
