Simple shell script

[OOzy Pal]

Dears,

I have the following script to start webmin and it sync'ed between my
laptop and desktop. How can I make the script detected if it is
running in the laptop or desktop. For example

Original Script
sudo /etc/webmin/start
firefox -new-tab http://laptop:10000/

Modified Script
sudo /etc/webmin/start
firefox -new-tab http://{HOST}:10000/

not sure
