Prefer networksetup and skip root runs

Primarily I wanted to incorporate @amartignoni's simplification through networksetup over use of a private API and implement a fix for issue #28 so that I had a one stop branch that would do what I needed.

This covers both scenarios.

Closes #29

Turns out this breaks support for SSIDs with spaces in the name. It only matches the final " lastword".

fix for SSIDs with spaces

networksetup -listallhardwareports | awk '/Wi-Fi/{getline; print $2}' | xargs networksetup -getairportnetwork | sed 's/[^:]*: //'

networksetup -listallhardwareports | awk '/Wi-Fi/{getline; print $2}' | xargs networksetup -getairportnetwork | sed 's/[^:]*: //'

That worked for me. Thanks!

Unfortunately this is broken as of MacOS 15.0. And I haven't been able to find any way to fix it without sudo, as every non-sudo command I've found lists the SSID as "<redacted>"

Try system_profiler SPAirPortDataType | grep -A2 'Status: Connected' | tail -n1 | sed 's/:$//' | xargs
