Port scanner in terminal for MacosX 10.9.x Marverick

/System/Library/CoreServices/Applications/"Network Utility.app"/Contents/Resources/stroke 127.0.0.1 49152 65535

with 127.0.0.1 being the ip address to scan and the range of ports to scan

The simplest solution is to add this line at the end of the $HOME/.profile file:

export PATH=/System/Library/CoreServices/Applications/"Network Utility.app"/Contents/Resources:$PATH

And then it is possible to use directly
stroke 127.0.0.1 49152 65535

The hidden applications are available in Onyx
