Bash script to suspend all of a reseller's cPanel accounts

Simple Bash script to suspend all of a reseller’s user accounts on a cPanel web server. It gets an accurate list of the reseller user’s sub-accounts on the cPanel server, and suspends each of them.
Example usage
./suspend-reseller-accounts <reseller>
You may wish to chmod u+x ./suspend-reseller-accounts
in order to make it easier to work with.
The Script
Without further delay, here’s the script. Enjoy!
