如何在solaris上获得完整的启动时间

Question

我正在努力寻找命令，甚至在Solaris（sun4u sparc SUNW，Netra-T12）框中找到完整的启动时间

的Solaris

who -b给了我Jun 22 11:09但没有年份

与last reboot | head -n 1

相同

然而，在我的Linux（GNU / Linux x86_64）框中，我能够获得完整的启动时间

的Linux

who -b给了我2014-08-23 11:09

任何帮助？

修改

apptrace uptime 2>&1

的输出

这是一种在{10} ksh或bash下在Solaris 10上获取启动时间的hackish方式：

perl -le "print scalar localtime hex(\"$(apptrace -v getutxent uptime 2>&1 | nawk '
/ut_type:/ {if($3=="0x2"){boot=1}}
boot == 1 && $0 ~ ".*tv_sec:.*" {sub("0x","",$3);print $3;exit}')\")"

请注意，您需要是root用户才能在Solaris 10上运行它，而不是在Solaris 11上运行它。

修改： 这是一种更简单的方法，不需要root权限：

perl -le "print scalar localtime $(kstat -pn system_misc -s boot_time|cut -f 2)"
