Thanks.
Here's a slightly shorter version. Picky, picky, picky. Looking gift
horse in the mouth.
I try to start all my scripts with "set -eu" so that more bugs will be
detected.
"set -e" causes the shell to exit if a command unexpectedly fails.
That is, a command returns non-zero and was invoked in a non-test
context. Just what you want.
It only causes the shell to exit if a simple command fails.
Best practice is not to use it at all.
<http://mywiki.wooledge.org/BashFAQ/105>
"set -u" tells the shell to treat a reference to an undefined
parameter as an error. It will make no difference in this script.
Until the script evolves more complexity.
There's no point to using set -u after a script has been debugged.
