[yast-devel] Tip: Write a compressed file system image with a progress report without a temporary file

[Martin Vidner]

xzsize() { xz --robot --list "$1" | awk '/^file/ { print $5 }'; }
XZ=img.xz; xzcat "$XZ" | pv -s $(xzsize "$XZ") | dd bs=1M conv=fsync 
of=/dev/sdcard

I've used this to test a recent Raspberry Pi image.
