I have a script for checking an unsuccesful ping, and I use the return
value:
ping -c 1 www.yahoo.com 1>/dev/null 2>/dev/null
if [ "$?" != "0" ]; then
An error has occured
else
Ping went OK
fi
See, ping has a return code 0 for a successfull ping, and 1 or 2 for an
error, depending on the error type.
