systemd-tmpfiles [OPTIONS...] [CONFIGFILE...]
systemd-tmpfiles-setup.service systemd-tmpfiles-setup-dev.service systemd-tmpfiles-clean.service systemd-tmpfiles-clean.timer
systemd-tmpfiles-setup.service systemd-tmpfiles-clean.service systemd-tmpfiles-clean.timer
If invoked with no arguments, it applies all directives from all configuration files. When invoked with --replace=PATH, arguments specified on the command line are used instead of the configuration file PATH. Otherwise, if one or more absolute filenames are passed on the command line, only the directives in these files are applied. If "-" is specified instead of a filename, directives are read from standard input. 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 and the file found that has the highest priority is executed.
Note that this option does not alter how the users and groups specified in the configuration files are resolved. With or without this option, users and groups are always resolved according to the host's user and group databases, any such databases stored under the specified root directories are not consulted.
This option is intended to be used when package installation scripts are running and files belonging to that package are not yet available on disk, so their contents must be given on the command line, but the admin configuration might already exist and should be given higher priority.
It is possible to combine --create, --clean, and --remove in one invocation (in which case removal and clean-up are executed before creation of new files). 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
