sfdisk Goodies

Just some quickies for today.

Copy a partition table from one disk to another

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

or

# sfdisk -d /dev/sdc > partition_table.out  
# cat partition_table.out | sfdisk /dev/sdc

Get the size of a disk

# /sbin/sfdisk -s /dev/sdf

And finally the coolest part.

Partition a disk for linux without specifying a size (making 1 big partition).

# echo L | sfdisk /dev/sdf

You can do something similar to make multiple partitions but I'll leave that up to you and some googling.
