linux 查看系统状态方法

Linux下如何查看系统启动时间和运行时间

1.uptime命令
输出:16:11:40 up 59 days, 4:21, 2 users, load average: 0.00, 0.01, 0.00

2.查看/proc/uptime文件计算系统启动时间
cat /proc/uptime
输出: 5113396.94 575949.85
第一数字即是系统已运行的时间5113396.94 秒，运用系统工具date即可算出系统启动时间

代码: 全选

date -d "$(awk -F. '{print $1}' /proc/uptime) second ago" +"%Y-%m-%d %H:%M:%S"

输出: 2008-11-09 11:50:31

3.查看/proc/uptime文件计算系统运行时间

代码: 全选

cat /proc/uptime| awk -F. '{run_days=$1 / 86400;run_hour=($1 % 86400)/3600;run_minute=($1 % 3600)/60;run_second=$1 % 60;printf("系统已运行：%d天%d时%d分%d秒",run_days,run_hour,run_minute,run_second)}'

输出:系统已运行：59天4时13分9秒
