systemd-tmpfiles 命令

常用示例

说明

systemd-tmpfiles creates, deletes, and cleans up volatile and temporary files and directories. Configuration files in /etc/tmpfiles.d/, /usr/lib/tmpfiles.d/, and related directories define what actions to take. The tool is automatically invoked during system boot by systemd services.
