SYSTEMD-TMPFILES(8) systemd-tmpfiles SYSTEMD-TMPFILES(8) NAME
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 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, 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. --help Prints a short help text and exits. 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 EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise. SEE ALSO
