<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>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>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.
