Fetching date in the format DD-MON-YYYY_HH24:MI:SS

Hi,

In Linux, if I need to fetch current date in the format DD-MON-YYYY_HH24:MI:SS, what needs to be the command?

Current Date - 29-MAY-2019

I executed the following command:

date +%d-%^b-%Y

It fetches the date 29-MAY-2019

I also want the timestamp to be connected. For.e.g it is 10:15:22 PM, it needs to be displayed as 29-MAY-2019_22:15:22

Please let me know how do I fetch the same.

Thanks,

Krishna
