<title>Description</title>
<para><command>systemd-tmpfiles</command> creates,
deletes, and cleans up volatile and temporary files and
directories, based on the configuration file format and
location specified in
<citerefentry><refentrytitle>tmpfiles.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
</para>
<para>If invoked with no arguments, it applies all
directives from all configuration files. If one or
more filenames are passed on the command line, only
the directives in these files are applied. If only
the basename of a configuration file is specified,
all configuration directories as specified in
<citerefentry><refentrytitle>tmpfiles.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>
are searched for a matching file.</para>

<para>It is possible to combine
<option>--create</option>, <option>--clean</option>,
and <option>--remove</option> in one invocation. For
example, during boot the following command line is
executed to ensure that all temporary and volatile
directories are removed and created according to the
configuration file:</para>
<programlisting>systemd-tmpfiles --remove --create</programlisting>

<title>Exit status</title>
<para>On success, 0 is returned, a non-zero failure
code otherwise.</para>
