You can use pkg delete -x rubygem-mime-types, or pkg update && pkg
upgrade is really what you need there.

Man pkg-query, but see below.

Shell autocomplete should be pretty easy to implement should you
choose, but given that many of the steps you describe are automated
anyway, it's hard to see any real advantage to manually manipulating
the data!

Rather than describing your current methods, you may be better off (in
a new thread) describing the *outcomes* that you would like, and we
can help you achieve them.
