poweroff 关闭系统,同时切断电源。差不多相当于执行 start poweroff.target --job-mode=replace-irreversibly 命令。但同时会向所有用户显示一条警告信息。若仅使用一次 --force 选项,则跳过单元的正常停止步骤而直接杀死所有进程,强制卸载所有文件系统(或以只读模式重新挂载),并立即关闭系统。若使用了两次 --force 选...
The systemctl command is the primary tool for managing the systemd system and service manager. It allows you to inspect and control the state of the systemd system and service manager. You can use it to start, stop, restart, reload, enable, disable, and view the status of services. ...
poweroff Shut down and power-off the system. This is mostly equivalent to start poweroff.target --irreversible, but also prints a wall message to all users. If combined with --force, shutdown of all running services is skipped, however all processes are killed and all file systems are un...
I have nothing against drop support for shutdown interface someday, but I think halt, reboot and poweroff should keep here forever. In addition to backward compatibility, them are useful and logical shorthands for systemctl [halt, poweroff, reboot] and just make sense. And shutdown is just ...
I am currently doing security hardening and modified many settings. I don't know which settings have been changed. I first discovered that the ssh service cannot be restarted, and the execution of systemctl restart ssh will time out. I executedyum reinstall -y systemd. After execution, it wa...
在执行 halt, poweroff, reboot 动作前,不发送警告消息。 --global 表示在全局用户单元目录(通常是 /etc/systemd/user/)上操作, 从而全局的操作一个用户单元,这会影响到所有未来登入的用户。 --no-reload 与enable,disable,edit命令连用, 表示在完成操作之后不重新加载 systemd 守护进程的配置(默认会自动重新加载...

This is only supported for user service managers (i.e. in conjunction with the <option>--user</option> option) or in containers and is equivalent to <command>poweroff</command> otherwise. This command is asynchronous; it will return after the exit operation is enqueued, without waiting...
