I use pv(1) all the time. Not a standard command, but everyone should install it and start using it. It replaces dd for most use cases and Just Does The Right Thing by default. It's part of my required packages list on every system, along with strace, htop, iotop, and vim.https://twitter.com/Yeah1Whatever/status/991568978479910913 …

You can just use cat (or nothing if just redirecting around another command). dd is total and utter cargo cult unless you need the seek/skip options. And even for that it's crap, because there's no reason for seek/skip to be in units of the transfer blocksize. And it's slow.
dd started as a joke about the syntax of IBM mainframe JCL program definitions (hence the silly a=b format). It became obsolete on OSes like Linux where block devices can be accessed byte-wise just fine and behave totally normally. But everyone still thinks "dd for blockdevs".

Please don't ask me why I have 80-column EBCDIC record format JCL job definition files^Wdataset members for compiling COBOL programs on my drive.pic.twitter.com/1lqdrkEifn
