| <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 absolute 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. |

| <title>Exit status</title> |

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