ok I am new to mac and am trying to learn my way around the bash prompt. I have downloaded and installed azlink to my droid. I have downloaded android-sdk-mac to my mac and put abd in usr/local/bin. I have downloaded and installed tunnelblick to my mac to intall openvpn. I am having trouble with the script from christie. first I tried highlighting it and saving but it will only save as a webpage. I the copied the script in applescript script editor and when I tried to save it to a folder I could come back to from the terminal it kept disappearing and also would not let me save it as azlink.sh. when I tried to run it from the script editor it said the script had syntax errors i.e. in the first line "{ cannot follow ()". when I copied it to a folder and just labeled it azlink and then try to change the name to azlink.sh the terminal window said no such file existed.
please tell me how to get this script on my mac and saved as ~/azlink,sh so I can run the chmod 744 command on it. azlink is up and running on the droid. tunnelblick is up and running on the mac. also I have OS X 10.6 running on the mac so if I have to use the above TunTap drivers do I just install them and then run the script or do they have to go to a specific folder.
I know this all seems simple to you guys but you've got to start somewhere to learn something different i.e. mac and unix vs. windows.
thanks in advance for any help.
