</p><p>For full details, you can view the <code class="inline-verbatim">systemctl.1</code> manual page.

|

</p><h1 id="synopsis">Synopsis</h1><pre class="src-block"><code class="language-shell">systemctl [OPTIONS...] COMMAND [COMMAND_ARGS...] [COMMAND_OPTIONS...]
|

</code></pre><h1 id="options">Options</h1><ul><li><p><code class="inline-verbatim">--user</code> runs the binary in user mode with the user-specific options and load-path.
|
||
|
|
See <a href="/wiki/linux.systemd#systemd-at-user-level">systemd at user-level</a> for more details.
|
||
|
|
</p></li><li><p><code class="inline-verbatim">--help</code> is an obvious one.
|
||
|
|
It prints a detailed help section of the command.
|
||
|
|
</p></li></ul><h1 id="subcommands">Subcommands</h1><ul><li><p><code class="inline-verbatim">enable UNIT</code> and <code class="inline-verbatim">disable UNIT</code> enables and disables units.
|
||
|
|
It mainly adds the unit activation at startup.
|
||
|
|
</p><ul><li><p><code class="inline-verbatim">--now</code> starts/stops the unit.
|
||
|
|
It is the equivalent of <code class="inline-verbatim">systemctl {enable,disable} UNIT && systemctl {start,stop} UNIT</code>.
|
||
|
|
Pretty handy if you intend to add the unit at startup and want to use it now.
|
||
|
|
</p></li></ul></li><li><p><code class="inline-verbatim">start UNIT</code> and <code class="inline-verbatim">stop UNIT</code> starts and stops the unit, respectively.
|
||
|
|
Though, this doesn't activate
|
||
|
|
</p></li><li><p><code class="inline-verbatim">restart UNIT</code> restarts the given unit.
|
||
|
|
This also reloads with the modified changes of the unit.
|
||
|
|
</p></li><li><p>In some cases where restarting the unit isn't enough, <code class="inline-verbatim">daemon-reload</code> will reload the daemon with the modified units.
|
||
|
|
systemd does not have reload-at-change for its unit.
|
||
|
|
That is, if a unit is modified, systemd will not run the modified version until reloaded.
|
||
|
|
</p></li><li><p><code class="inline-verbatim">show-environment</code> shows the environment variables of the system.
|
||
|
|
</p></li><li><p><code class="inline-verbatim">list-units [PATTERN...]</code> is self-explanatory ;p.
|
||
|
|
</p></li><li><p><code class="inline-verbatim">is-active PATTERN...</code> prints the status of the matched unit and exits successfully if it's active.
