已知三个时间变量：

time1="Fri Aug 23 11:35:21"

time2="Mon Sep 2 16:18:09"

time3="Tue Sep 3 16:06:33"

已知这三个时间可以确定是发生在2011-2013年，如何快速确定是哪一年呢？

希望输出:

time1="2013/8/23 11:35:21"

time2="2013/9/2 16:18:09"

time3="2013/9/3 16:06:33"

#!/bin/bash time1="Fri Aug 23 11:35:21" time2="Mon Sep 2 16:18:09" time3="Tue Sep 3 16:06:33" time4="Sun Dec 2 16:06:34" for((i=1;i<=4;i++)); do for((j=2011;j<=2013;j++)); do str=$(eval echo $time$i) WEEK_DAY=$(date -d "${str:0:10} $j ${str:10}" "+%a") if [ "${str:0:3}" == $WEEK_DAY ]; then echo time$i="$(date -d "${str:0:10} $j ${str:10}" "+%Y/%m/%d %T")" # break fi done done
