This page lists examples of the dd block size flag (i.e. bs=) on English language pages.

User-mode Linux

dd if=/dev/zero of=rootfs bs=1MB count=1000

Remote Arch Linux Install

# dd if=/dev/zero of=/swapfile bs=1024 count=512288

USB Installation Media

# dd count=1 bs=512 if=/dev/zero of=/dev/sdx

Windows and Arch Dual Boot

dd if=$my_boot_part of=/media/win/linux.bin bs=512 count=1

Dm-crypt with LUKS

# dd if=/dev/urandom of=mykeyfile bs=512 count=4
# dd if=/dev/urandom of=secretkey bs=512 count=4


$ dd if=/dev/zero of=image.img bs=1G count=0 seek=[NUMBER_OF_GB]

JFS Filesystem

dd bs=4k if=/dev/hdc1 of=/dev/hdj1

Installing ArchPPC on a PS3
