|
|
|
|
<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

<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>,

|
executed to ensure that all temporary and volatile directories are

|
removed and created according to the configuration file:</para>

<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.
