changing format of date shell

Question

I want to change date format of last reboot time. How can I do this? Any idea ? I cut the other things from last reboot command. The last seems :

Output :  1 Nov 2015

But I want like this :

dd/mm/yyyy : 01/11/2015

Since you already cut the output you just have to convert it to different format, try below you will find your expected format.

export DATE="1 Nov 2015"
date -d"$DATE" +%d/%m/%Y
01/11/2015
