Oh you can do this with sh not just bash. Bash makes it easier. I had to do
stuff like this back in networking class in early 90's using ksh and sh. Damn
now I sound old.

Subject: [raspberry-vi] Re: trouble shrinking partition
I have a script for writing/creating Pi Images with dd because it's one of
those commands whose syntax is a bit too complex and usage a bit too infrequent
for me to memorize the important bits.
That said, I think the hard part of converting the shrinkage instructions to a
script might lie in that at least part of the instructions involve using
fdisk(and possibly other utilities) interactively, which doesn't lend itself
well to scripting and that there are some steps where you take a number
outputted from one command and use it as a parameter elsewhere, often with a
unit conversion in-between, and I'm not sure piping alone can handle that.
I'm sure a script could be written to automate the process, and failing that, a
program could be written to do it, but I think the former is beyond my current
knowledge of Bash scripting, and the latter is well beyond my knowledge in C++,
the programming language I'm most comfortable with.
Though, one would think there would already exist a tool for this... I mean,
setting up one machine and then creating an image that can be written to other
machines to save time isn't anything new, nor did it come along with the first
models of the Raspberry Pi and removable/network storage for distributing the
image was more limited in the past than today, so keeping images small would be
important even if you could be sure all the target machines had at least as
much storage as the master.
As an aside, the summer following when I graduated with my Associates Degrees,
I got an internship with my community college's Computer Administration team
and helped them deploy images to the computer labs used for the college's IT,
Programming, and CAD courses, totalling close to 200 machines across more than
half-a-dozen labs.
