Linux – How to skip the luksFormat prompt

linuxluks

If I setup a new luks volume with "cryptsetup –verbose –cipher=aes-cbc-essiv:sha256 –key-size=256 luksFormat /dev/foo /my/keyfile" it requires me to enter "YES" to actually do anything. Is there a way to skip this prompt, so I can just run it from a script?

--batch-mode should do exactly that.

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

It looks like the EBS volume was added later as sda. So, sda{1,2} points to the virtual disk that the instance was booted from and sda points to the EBS volume. This might cause problems with programs that assume sda{1,2} to be partitions of sda.
