Learning the shell well teaches more about about programming, but
learning 'ed' well teaches some quite fundamental things about
applications and data, as well as practical things about using basic
regular expressions effectively, etc.

It's too bad /usr/share/doc/usd/09.edtut is empty in NetBSD
distributions.... A half hour reading through that paper, even without
a live computer to work through the examples with, would give you a good
head-start on learning "ed".
(there's no political or legal excuse I can see for this (and other
similar) documents being missing from NetBSD any more -- they've been
freely available for years)
Of course since it is freely avaliable you can find it (or at least its
troff source) elsewhere:
Then when you're done with that one the next step is this one:
Luckily both papers can be found in the following ready-to-read version:
