Answer 1

date --date='Fri Nov 3 17:50:23 2017' +"%Y-%m-%d %H:%M:%S"

ps如果您想要的输出中'T'不是拼写错误，只需用'T'改变空格

#!/bin/bash
#Declare
zero=0
Time_S=T
Jan=1
Feb=2
Mar=3
Nov=11
     string="Fri Nov 3 17:50:23 2017"
     s1=$(echo $string|cut -d " " -f5)
     s2=$(echo $string|cut -d " " -f2)
     s3=$(echo $string|cut -d " " -f3)
     s4=$Time_S$(echo $string|cut -d " " -f4)
     if [ $s3 -lt 10 ];then
        echo "valuse is less than 10"
         s3=$zero$s3
    else
        s3=$(($s3))
    fi
     echo "$s1-$(($s2))-$s3$s4"
