shell脚本计算时间差
2022-01-20 21:47 abce 阅读(2600) 评论(0) 编辑 收藏 举报#! /bin/bash
beginTime=$(date "+%Y-%m-%d %H:%M:%S")
echo "beginTime:" $beginTime
sleep 12
endTime=$(date "+%Y-%m-%d %H:%M:%S")
echo "endtime:" $endTime
duration=$(($(date +%s -d "${endTime}")-$(date +%s -d "${beginTime}")));
echo "时间差:" $duration"s"
其中
%s表示seconds since 1970-01-01 00:00:00 UTC -d表示display time described by STRING, not 'now'
执行演示：
# source a.sh beginTime: 2022-01-20 19:19:30 endtime: 2022-01-20 19:19:42 时间差: 12s
