.SH "DESCRIPTION"
.PP
\fBsystemd\-tmpfiles\fR
creates, deletes, and cleans up volatile and temporary files and directories, based on the configuration file format and location specified in
\fBtmpfiles.d\fR(5)\&.
.PP
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
\fBtmpfiles.d\fR(5)
are searched for a matching file\&.
.SH "OPTIONS"
.PP
The following options are understood:
.PP
\fB\-\-create\fR
.RS 4
If this option is passed, all files and directories marked with
\fIf\fR,
\fIF\fR,
\fIw\fR,
\fId\fR,
\fID\fR,
\fIv\fR,
\fIp\fR,
\fIL\fR,
\fIc\fR,
\fIb\fR,
\fIm\fR
in the configuration files are created or written to\&. Files and directories marked with
\fIz\fR,
\fIZ\fR,
\fIt\fR,
\fIT\fR,
\fIa\fR, and
\fIA\fR
have their ownership, access mode and security labels set\&.
.RE
.PP
\fB\-\-clean\fR
.RS 4
If this option is passed, all files and directories with an age parameter configured will be cleaned up\&.
.RE
.PP
\fB\-\-remove\fR
.RS 4
If this option is passed, the contents of directories marked with
\fID\fR
or
\fIR\fR, and files or directories themselves marked with
\fIr\fR
or
\fIR\fR
are removed\&.
.RE
.PP
\fB\-\-boot\fR
.RS 4
Also execute lines with an exclamation mark\&.
.RE
.PP
\fB\-\-prefix=\fR\fB\fIpath\fR\fR
.RS 4
Only apply rules with paths that start with the specified prefix\&. This option can be specified multiple times\&.
.RE
.PP
\fB\-\-exclude\-prefix=\fR\fB\fIpath\fR\fR
.RS 4
Ignore rules with paths that start with the specified prefix\&. This option can be specified multiple times\&.
.RE
.PP
\fB\-\-root=\fR\fB\fIroot\fR\fR
.RS 4
Takes a directory path as an argument\&. All paths will be prefixed with the given alternate
\fIroot\fR
path, including config search paths\&.
.RE
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Print a short help text and exit\&.
.RE
.PP
\fB\-\-version\fR
.RS 4
Print a short version string and exit\&.
.RE
.PP
It is possible to combine
\fB\-\-create\fR,
\fB\-\-clean\fR, and
\fB\-\-remove\fR
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:
.sp
.if n \{\
.RS 4
.\}
.nf
systemd\-tmpfiles \-\-remove \-\-create
.fi
.if n \{\
.RE
.\}
.SH "UNPRIVILEGED --CLEANUP OPERATION"
.PP
\fBsystemd\-tmpfiles\fR
tries to avoid changing the access and modification times on the directories it accesses, which requires
\fBCAP_ADMIN\fR
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\&.
.SH "EXIT STATUS"
.PP
On success, 0 is returned, a non\-zero failure code otherwise\&.
.SH "SEE ALSO"
.PP
