This is what I have on my laptop:
LOCATION=$(scselect 2>&1 | grep "^ \*" | cut -f 2)
case "$LOCATION" in
"(Home)")
unset http_proxy
unset FTP_PROXY
;;
"(Work)")
export http_proxy="http://workproxy:3128";
export FTP_PROXY="http://workproxy:3128";
;;
*)
echo unknown location $LOCATION
;;
esac
There are apps that will switch locations for you automatically based on
AirPort SSID or other network characteristics. Alternatively you could
look at the output of something like 'networksetup -getairportnetwork
en1' instead of the scselect command used above .
