我的 Linux 系统运行了多长时间？

我可以在终端中输入一个命令来告诉我上次重新启动机器的时间吗？

答案1

uptime

如果你想要数字形式，它是第一个数字/proc/uptime（以秒为单位），所以最后一次重新启动的时间是

date -d "$(</proc/uptime awk '{print $1}') seconds ago"

正常运行时间包括处于低功耗状态（待机、暂停或休眠）的时间。

答案2

您可以使用uptime或last

只看最后一次

last reboot -F | head -1 | awk '{print $5,$6,$7,$8,$9}'

更一般地说

last reboot

注意和警告

The pseudo user reboot logs in each time the system is rebooted.  
Thus last reboot will show a log of all  reboots since the log file was created.

答案3

我通常使用who -b，它会产生如下输出：

$ who -b
         system boot  2014-05-06 22:47
$

它告诉我机器上次启动的日期和时间，而不是自上次启动以来经过的时间。

该命令也适用于许多其他 Unix 系统（Solaris，...）。

答案4

使用启动时间，您将获得所需的所有信息，例如：
