I used to write while-loop wrapper scripts like that to monitor
various things, until about a year ago when I discovered the watch(1)
command, which clears the screen and then runs a command repeatedly
forever.

For example, I threw together a script to parse the openvpn logs and
print a report of who's connected and for how long, then I run it
with the watch command:

     watch --interval=10 whoson-ovpn

Every 10 seconds, watch(1) clears the screen and then runs the script.
