if you need a progress indicator while using dd you will find this interesting.
sudo dd if=/dev/zero bs=2048 | pv -s 8G | sudo dd bs=2048 of=/dev/null
just give “pv” the size of the input device (image) and pipe dd through.

this post is just a note to myself (like many others on this blog)
ls -t /dev/sd* | head -1 | /bin/sed -e 's/^\/dev\/*//' |cut -c 1-3
i had to figure out a way to determine the name of the usb-thumb-drive i JUST connected within a script – well.. it works but im open for suggestions 🙂
first i list all devices that begin with “sd” sorted by creation time/date
then i filter the newest device and cut off the string “/dev/”
at last i cut the first 3 letters of the string because that’s all i need (i do not need to know the partition number of the device)
