# ABOUT THIS EXTENSION ATTRIBUTE
#
# NAME
# CurrentWifiNetworkEA.sh -- Reports currently selected Wifi interface
#
# RESULT TYPE
# String
#
# DESCRIPTION
# This extension attribute script was designed to report the currently selected Wifi interface
# on an OS X computer.
#
# NOTES
# While the actual commands to parse and filter out the current Wifi interface from the results
# of using the networksetup command have not changed from the scripts previously posted on JAMF
# Nation, the versionCompare() function has been introduced to future-proof the comparison of OS X
# versions by doing an arithmetic comparison rather than a string comparison. This function should
# be re-usable in any bash scripts where this kind of comparison needs to be made.
# The determination of the Wi-Fi network has been updated to work correctly with OS X 10.7 and
# above (up to 10.10 at the time of writing).
