Hi Eric

Thank you for that, I think I see one thing I was doing wrong (putting the ping 
into the if!)

Running your code in the command window I get (Following the successful ping)

TESTV=0: Command not found.
TESTV: Undefined variable.

As you can tell I am learning this syntax!

Can you help me further?

With thanks

David Hingston

Here's what I'd use:

ping -c 1 a.b.c.d; TESTV=$?; if [ $TESTV != 0 ]; then `ifconfig em0  
down`; fi
