NAME
systemd-tmpfiles, systemd-tmpfiles-setup.service, systemd-tmpfiles-setup-dev.service,

SYNOPSIS
systemd-tmpfiles [OPTIONS...] [CONFIGFILE...]

systemd-tmpfiles-setup.service

systemd-tmpfiles-setup-dev.service

systemd-tmpfiles-clean.service

systemd-tmpfiles-clean.timer

DESCRIPTION
systemd-tmpfiles creates, deletes, and cleans up volatile and temporary files and
directories, based on the configuration file format and location specified in
tmpfiles.d(5).

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 tmpfiles.d(5) are searched for a matching file.

OPTIONS
The following options are understood:

--create
If this option is passed, all files and directories marked with f, F, w, d, D, v, p,
L, c, b, m in the configuration files are created or written to. Files and directories
marked with z, Z, t, T, a, and A have their ownership, access mode and security labels
set.

--clean
If this option is passed, all files and directories with an age parameter configured
will be cleaned up.

--remove
If this option is passed, the contents of directories marked with D or R, and files or
directories themselves marked with r or R are removed.

--boot
Also execute lines with an exclamation mark.

--prefix=path
Only apply rules with paths that start with the specified prefix. This option can be
specified multiple times.

--exclude-prefix=path
Ignore rules with paths that start with the specified prefix. This option can be
specified multiple times.

--root=root
Takes a directory path as an argument. All paths will be prefixed with the given
alternate root path, including config search paths.

-h, --help
Print a short help text and exit.

--version
Print a short version string and exit.

It is possible to combine --create, --clean, and --remove 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:

systemd-tmpfiles --remove --create

UNPRIVILEGED --CLEANUP OPERATION
systemd-tmpfiles tries to avoid changing the access and modification times on the
directories it accesses, which requires CAP_ADMIN 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.

EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
