As I needed this script to function a couple of days ago, I aborted the "read from external file" concept and hard-coded the box names into a 'for' loop (per Just_Ice's original concept). It worked fine. (Thanks, Ice!)
Every 2-3 months or so I will need to change the list of server names. This would be easy and convenient by using an external file of box names, but honestly, it's just as easy and convenient to edit the script we've been discussing. Either way, it's a quick 'vi' edit on a file.
After my script was working, a coworker supplied a suggestion. I haven't tried it yet, but I thought I'd supply it here for comments:
Instead of hard-coded host names (ex: for host in server1 server2 server3), use an external file and this...
for host in `cat listofhostsfile`
Seems reasonable...

SYSTEMD-RC-LOCAL-GENERATOR(8) systemd-rc-local-generator SYSTEMD-RC-LOCAL-GENERATOR(8)
NAME
systemd-rc-local-generator - Compatibility generator for starting /etc/rc.local and /usr/sbin/halt.local during boot and shutdown
SYNOPSIS
/lib/systemd/system-generators/systemd-rc-local-generator
DESCRIPTION
systemd-rc-local-generator is a generator that checks whether /etc/rc.local exists and is executable, and if it is pulls the
rc-local.service unit into the boot process. This unit is responsible for running this script during late boot. Note that the script will
be run with slightly different semantics than the original System V version, which was run "last" in the boot process, which is a concept
that does not translate to systemd. The script is run after network.target, but in parallel with most other regular system services.
systemd-rc-local-generator also checks whether /usr/sbin/halt.local exists and is executable, and if it is pulls the halt-local.service
unit into the shutdown process. This unit is responsible for running this script during later shutdown.
Support for both /etc/rc.local and /usr/sbin/halt.local is provided for compatibility with specific System V systems only. However, it is
strongly recommended to avoid making use of these scripts today, and instead provide proper unit files with appropriate dependencies for
any scripts to run during the boot or shutdown processes.
systemd-rc-local-generator implements systemd.generator(7).
