Only works on Linux, due to using special system calls, such as
splice, sendfile or mmap.

odd -- optimized dd (C) 2011-2017 Sebastian Krahmer
Usage: odd [if=F1] [of=F2] [send|mmap=N MB|cores=N] [bs=N] [skip=N] [count=N]
[quiet] [direct] [nosync]
Switches mimic classical 'dd' behavior. You can choose copy strategies:
'send' uses sendfile(2), 'mmap' copies via mmap(2) in N Megabyte chunks.
Default is using splice(2). You can balance to 'cores' CPU cores
