Thanks for the response.
/etc/hostname contains "domain.com" only with no trailing space or line.
This is the top of the script, so $thehostname is only declared and filled here.
I have manually edited /etc/hostname many times in testing this. As soon as I run this script, it fixes the incorrect hostname, but always adds a trailing newline.

hostname
HOSTNAME(5) hostname HOSTNAME(5)
NAME
hostname - Local hostname configuration file
SYNOPSIS
/etc/hostname
DESCRIPTION
The /etc/hostname file configures the name of the local system that is set during boot using the sethostname(2) system call. It should
contain a single newline-terminated hostname string. The hostname may be a free-form string up to 64 characters in length; however, it is
recommended that it consists only of 7-bit ASCII lower-case characters and no spaces or dots, and limits itself to the format allowed for
DNS domain name labels, even though this is not a strict requirement.
Depending on the operating system, other configuration files might be checked for configuration of the hostname as well, however only as
fallback.
You may use hostnamectl(1) to change the value of this file from the command line.
HISTORY
The simple configuration file format of /etc/hostname originates from Debian GNU/Linux.
