alive-alive-not-alive v1.0.1

Alive Alive Not-Alive

Use node-ping to filter a list of hostnames (provided on stdin) based on whether they are pingable (sent to stdout) or not (sent to stderr).

./alive-alive-not-alive <<<EOF
npmjs.com
ryandahlrockshuzzahhuzzahhuzzah.com
nodejs.org
anotherfakedomain_nopenopenope.com
EOF

Real ones go to stdout, unreachable addresses go to stderr.
