If you do not know the device name for the Wi-Fi network adapter, on a Mac you can use the following examples:
➜ apuntes git:(master) ✗ networksetup -getairportpower $(system_profiler SPAirPortDataType | awk -F: '/Interfaces:/{getline; print $1;}')
Wi-Fi Power (en0): On
or
➜ apuntes git:(master) ✗ ifconfig $(system_profiler SPAirPortDataType | awk -F: '/Interfaces:/{getline; print $1;}') | awk '/status:/{print $2}'
active
Or we can use wdutil
(Wireless Diagnostics command line utility):
➜ apuntes git:(master) ✗ wdutil --help
usage: sudo wdutil diagnose [-q] [-f outputDirectoryPath]
-q may be specified to suppress legal prompt and Finder window
sudo wdutil info
sudo wdutil log [{+|-} {system|wifi}]+
sudo wdutil dump
sudo wdutil clean
