Quickly ping range of IP adresses and return only those that are online

{ for i in {1..254}; do ping -c 1 -W 1 192.168.1.$i & done } | grep "64 bytes"
Tested in Debian, ymmv. - c 1 : send only one ping;; -W 1: wait for one second and then exit ping, assuming target IP is not available; change as needed (-W 0.5 for half a second, smaller or greater value depending on network speed/latency)

Although purchasing Instagram followers from http://bmmagazine.co.uk/business/top-4-websites-to-buy-instagram-followers-uk/ offers some advantages, it should also be considered that purchasing followers can cost money. Business owners that want to increase their follower count but do not have the money to spend on it should consider purchasing Instagram users. from third parties that can help them grow their online following.

It's really cool 'cause nmap automatically filters hosts that are up and it gives you host type + MAC Address. Excellent. Thanks also for explaining about Python. jcpenney kiosk
