<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>
</refsect1>
<refsect1>
<title>Options</title>
<para>The following options are understood:</para>

<listitem><para>Ignore rules with

multiple times.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--root=<replaceable>root</replaceable></option></term>
<listitem><para>Takes a directory path
as an argument. All paths will be
prefixed with the given alternate <replaceable>root</replaceable>
path, including config search paths.
</para></listitem>
</varlistentry>
<xi:include href="standard-options.xml" xpointer="help" />
<xi:include href="standard-options.xml" xpointer="version" />
</variablelist>
<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>
</refsect1>
<refsect1>
<title>Unprivileged --cleanup operation</title>
<para><command>systemd-tmpfiles</command> tries to
avoid changing the access and modification times on
the directories it accesses, which requires
<constant>CAP_ADMIN</constant> privileges. When
running as non-root, directories which are checked for
files to clean up will have their access time bumped,
which might prevent their cleanup.
</para>

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