systemd-tmpfiles, systemd-tmpfiles-setup.service, systemd-tmpfiles-setup-dev.service, systemd-tmpfiles-clean.service, systemd-tmpfiles-clean.timer — Creates, deletes and cleans up volatile and temporary files and directories
systemd-tmpfiles [OPTIONS...] [
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 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
are searched for a matching file.
The following options are understood:
If this option is passed, all files and
directories marked with
in the configuration files are created or written to. Files
and directories marked with
A have their ownership, access mode and
security labels set.
If this option is passed, all files and directories with an age parameter configured will be cleaned up.
If this option is passed, the contents of
directories marked with
R, and files or directories themselves
Execute "user" configuration, i.e.
files in user configuration directories.
Also execute lines with an exclamation mark.
Only apply rules with paths that start with the specified prefix. This option can be specified multiple times.
Ignore rules with paths that start with the specified prefix. This option can be specified multiple times.
Takes a directory path as an argument. All paths will be prefixed with the given alternate
root path, including config search paths.
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.
It is possible to combine
--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
systemd-tmpfiles tries to avoid changing
the access and modification times on the directories it accesses,
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
On success, 0 is returned. If the configuration was invalid (invalid syntax, missing
arguments, …), so some lines had to be ignored, but no other errors occurred,
65 is returned (
1 is returned
