Deleting non-standard Admin account

Not sure if you did a search but there was a very similar question asked earlier this week. I can't find it right now but did find this:

Yeah did a couple searches but nothing fit the right way. My biggest fear is that somehow the account under UID 500 get sacked and then we got bigger problems. I'll keep looking.

Something quick and dirty I came up with to get you started:

#!/bin/bash

#get list of admins
admins=$(dscl . -read /Groups/admin GroupMembership | sed 's/GroupMembership: //')

#for each username in admins, check it's UniqueID, if it's known to be greater than 500, remove it.
for user in $admins; do
    userID=$(dscl . -read /Users/$user UniqueID 2> /dev/null | sed 's/UniqueID: //')
    if [[ ! -z "$userID" ]]; then
        if [[ $userID -gt 500 ]];then           
            #delete the user account via dscl
            echo "deleting user $user because it's an admin with a Unique ID:$userID greater than 500"
        else
            # keep the user
            echo "keeping user $user because it's Unique ID: $userID is less than 500"
        fi
    fi
done
