Open a terminal tab at a specified directory from command line

Here is a small script I knocked up :

#!/usr/bin/osascript
on run argv
  set dir to quoted form of (first item of argv)
  tell app "Terminal" to do script "cd " & dir
end run

If you save this and make it executable

chmod +x script_filename

and then run it

script_filename ~/Desktop

then it will open up a new terminal window and change to the directory in the argument.

Possible I am missing the point, but can't you Export the profile as a .terminal file and add that to your Login Items?

Export:

Add the exported file to Login Items:
