DD, monitor current status and speed

One of the most useful command in Linux, is dd. We also know that dd provides info regarding the current status, using kill:

kill -USR1 <pidof dd>

but I really prefer the pv way (apt-get install pv)

# We usually do this way
dd if=my.iso of=/dev/sdb

# This is the "pv" way
dd if=my.iso | pv | dd of=/dev/sdb

Of course, you need apt-get install -y pv before, but piping through pv, allow you to see the status, in real time.

dd if=xubuntu-16.04.2-desktop-i386.iso | pv | dd of=/dev/sdb
