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.
The following options are understood:
--create¶If this option is
passed, all files and directories
marked with f,
F,
w,
d,
D,
p,
L,
c,
b,
m in the
configuration files are created or
written to. Files and directories
marked with z,
Z,
m 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, all files and directories
marked with r,
R in the
configuration files are
removed.
--boot¶Also execute lines with an exclamation mark.
--prefix=path¶Only apply rules that apply to paths with the specified prefix. This option can be specified multiple times.
--exclude-prefix=path¶Ignore rules that apply to paths 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¶--version¶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
