status of a tap device ...

[Jason Hellenthal]

Ifconfig -v tap0 ? Does this work for you ?

Also upon opening a tap...

ifconfig tap create

Will return the numeric portion of the tap that was created with $?

So scripting it out it would be similar to...

ifconfig tap create && export MYTUNIS="$?"

echo "tap$MYTAPIS"
