Yeah, that's what it is. I may not have understood what Stan was
getting at there, honestly.

This script is all about running commands and filtering their output
through sed and awk. It makes sense as a bash script. If there's a
more powerful programming language that can do the equivalent of
```
shopt -s lastpipe
command-1 |
command-2 |
while read whatever; do
[...]
done
```
in some reasonable way, then count me in.
As it is, what I've got works really well, as much as writing it
definitely took a little creativity here and there.
Eventually, it's going to gain a (probably Ruby) helper program to
serve as a coprocess that maintains a persistent TCP connection and
handles REST API interactions. I know better than to try doing that in
bash.
This is effectively replacing a bunch of Python that's served as a
great example of what not to do.
I'd like to think I'm helping to move the ball forward here,
leveraging the experience of trying to do some fairly complicated
stuff in bash.
