Linux下查看开机时间与进程情况
时间:2014-11-29 13:48 来源:linux.it.net.cn 作者:IT
用到二个linux命令:一个是top (查看进程) 一个就是uptime(查看开机到现在有多久)
1,查看开机时间:
代码示例:
[root@ahlinux~]# uptime
08:30:08 up 70 days, 9:37, 1 user, load average: 0.00, 0.00, 0.00
2,查看进程:
代码示例:
[root@ahlinux~]# top
top – 08:35:35 up 70 days, 9:39, 1 user, load average: 0.00, 0.00, 0.00
Tasks: 103 total, 2 running, 101 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 514896k total, 484812k used, 30084k free, 155784k buffers
Swap: 1052248k total, 88k used, 1052160k free, 222256k cached

244 root 16 -5 0 0 0 S 0.0 0.0 0:00.00 aio/0
这都是没有加入参数的情况下显示的。
