When you work with the command line, you’ll notice that you cannot navigate “into” aliases created with the Finder when in Terminal. For example, you cannot issue a cd command into an alias, because Terminal just doesn’t recognize it is such.

From the command line, however, you can use symbolic links , the Unix equivalent. While you can create these from Terminal using the ln -s command, it is useful to be able to create them from the Finder as well. Here is a simple AppleScript that can do just that.

Paste the following code into a Script Editor window, then save it as an application:

	on run
	 open {choose file with prompt ¬
	 "Choose a file to create a symbolic link:" without invisibles}
	end run
	on open the_files
	 repeat with i from 1 to (count the_files)
	   set posix_path to POSIX path of (item i of the_files)
	   if posix_path ends with "/" then set posix_path to ¬
	   text 1 thru -2 of posix_path
	   do shell script "ln -s " & quoted form of posix_path ¬
	   & " " & quoted form of (posix_path & ".sym")
	  end try
	 end repeat
	end open

If you double-click the resulting AppleScript droplet, it will prompt you to select a file; the script will then create a symbolic link in the same folder where the current file is, and you can move that link wherever you want. If you want to create a symbolic link of a folder, just drag the folder onto the droplet; you can also make multiple symbolic links by dragging them on the droplet at the same time. The script adds a .sym extension to the links it creates, so you can spot them easily.
