How can I quickly copy a GPT partition scheme from one hard drive to another?

On a non GPT partition table I can do

sfdisk -d /dev/sda | sfdisk /dev/sdb.

But sfdisk doesn't support GPT partition tables. What can I use instead?

I'm looking for a one or two command solution, not just using GNU parted to output the partition sizes and then manually making them again.

Install gdisk which is available in the Ubuntu Universe repositories.

Then use the sgdisk command (man page here) to replicate the partition table:

sgdisk /dev/sdX -R /dev/sdY 

sgdisk -G /dev/sdY

The first command copies the partition table of sdX to sdY (be careful not to mix these up). The second command randomizes the GUID on the disk and all the partitions. This is only necessary if the disks are to be used in the same machine, otherwise it's unnecessary.
