clean.timer – Creates, deletes and cleans up volatile and temporary
files and directories
systemd-tmpfiles [OPTIONS…] [CONFIGFILE…]
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
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:
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.
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 D
or R, and files or directories themselves marked with r or R are
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.
Print a short help text and exit.
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.
On success, 0 is returned, a non-zero failure code otherwise.
