Reinstalling the whole OS just to fix a typo doesn&rsquo;t sound rational.</p> <p>One solution can be removing the wrong user and creating a new one, with a correct name. But in that case, all programs that had configs in the user&rsquo;s home directory will be messed up, which is very bad.</p> <p>The correct way of renaming a Linux user and his home directory is to use the <code>usermod</code> command:</p> https://www.oorkan.dev/blog/controlling-the-time-settings-in-linux-via-timedatectl/ Sun, 20 Sep 2020 07:35:00 +0400 https://www.oorkan.dev/blog/controlling-the-time-settings-in-linux-via-timedatectl/ <p>If our Linux OS has been booted using <code>systemd</code>, we can use a program called <code>timedatectl</code> to control its time settings. <code>timedatectl</code> is a utility of the <code>systemd</code> service manager and won&rsquo;t be available in systems that aren&rsquo;t using it <a href="https://distrowatch.com/search.php?defaultinit=Not&#43;systemd" target="_blank" rel="noopener noreferrer">🔗</a>. When typing <code>timedatectl status</code> in the terminal, it will show us the current time settings, like local time, time zone, network time synchronization, etc. Most of the systems, if not all, will pick this command as the default, and we can simply run <code>timedatectl</code> instead.</p>
