watch-vox script - a vox monitor

FYI - just a bit of fun... for anyone else who wants to keep an eye on Vox.

To run it :

1) save the script somewhere as :   watch-vox.sh

2) start a Terminal or PuTTY or ssh session

3) cd to the folder where you saved the script

4) then run it using:   ./watch-vox.sh

.

Here's the script :

#!/bin/bash
#...for Solaris, change the above to:   #!/usr/bin/bash
#...but, on my test x86 Solaris 10.13 and Solaris 11.3 systems, I didn't need to.
