If you need to determine the currently connected WiFi network from a command line interface (CLI), aka a shell prompt, on an Apple OS X system, e.g., a MacBook Pro laptop, you can do so by opening a Terminal window (the application is in
/Applications/Utilities) and
issuing the command networksetup -getairportnetwork wifi_device
where wifi_device is the port used for wireless connections
on the system. You can determine the hardware port used for Wi-Fi
connectivity on the system by issuing the command
networksetup -listallhardwareports and then piping its
output into the grep command looking for
Wi-Fi in the output and when it is found displaying that line and
the two lines after it. E.g., in the example below, en0 is the
relevant device interface for wireless connections and the
SSID for the currently connected Wi-Fi network is "Hogwarts".$ networksetup -listallhardwareports | grep -A 1 "Wi-Fi" Hardware Port: Wi-Fi Device: en0 $ networksetup -getairportnetwork en0 Current Wi-Fi Network: Hogwarts
