For curiosity, where's 42 from?
I want to read all format specific information there, and because
this is the last information emitted by qemu_img -info, I have to
grep everything after the line "Format specific information:" until
EOF – I didn't find an easy way to do this, so I just chose a number
of lines which seemed enough to fetch all of that format specific
info (currently, 2 would suffice).
