====== Make your Mac feel at Home ======

A small snippet from one of my scripts which tests whether your Mac is in the given (home) WLAN.

<code bash>
#
# Path to 'airport' executeable, as of Mac OS X 10.5.
AIRPORT="/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport"
#
# Set this to your Home WLAN SSID (name):
HOMESSID="mycastle"
#
# Get SSID info from 'airport' and search for $HOMESSID
SSID=$(${AIRPORT} --getinfo | grep ' SSID:')
SSID=$(echo ${SSID} | grep "^SSID: ${HOMESSID}\$")
#
# Branch depending on grep's return code.
if [ "$?" == "0" ]; then
	# in home wlan
	echo "home sweet home..."
else
	# not at home
	echo "on the road again..."
fi
</code>

To use this code, set the ''HOMESSID'' to your ''SSID'' (the name of the wireless network) and replace the two echo lines with your code.
