So one drawback with this, that I ran into is:
nwe@deb13:~$ pv
bash: pv: command not found
For anyone working a lot on isolated "air-gapped" networks with no quick
easy access to the apt repositories, pv is thus less useful.
I don't recall having ever had to install dd. I installed pv and skimmed
over its man page. Yes, I can see it looks useful. While depending on dd
gets me the benefit of being able to expect it is going to be there when
I need it without having to install it first.
I try to use with "lowest common denominator" tools for backups,
archives, images, etc., so that the tools are available "out of the box"
on the platforms I use -- Linux (including Debian), BSD, Cygwin, and
MacOS -- sh(1), bash(1), tar(1), gzip(1), dd(1), etc.. That said, some
platforms do require additional packages/modules -- ssh(1), sshd(8),
rsync(1), perl(1), various Perl modules, etc.. I have looked at newer
tools that offer parallel computation via multi-core/thread processors,
and either have found that they are missing on one or more platforms or
have wondered if they would be around in 10, 20, etc., years.
