Create a symbolic link in the Mac OS X Finder

"What about that
creating symbolic links in the Finder via AppleScript ?

Here's the most relevant script in that link:

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)
try
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

Just paste it into AppleScript Editor and save it as an application. Then you can drag it over your finder's toolbar or link it on the dock."

"An applescript at the link provided by user nuc answered my question. Here is the applescript reproduced in case that link disappears.

I preferred the script given by the commenter jonn8n, which was also reproduced as Macworld article.

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)
try
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

I saved this as an application using Script Editor and dragged the application to the Finder sidebar so I can now create symbolic links by dragging files or folders onto the application icon."

"A possible improvement on this script would be changing the run handler to use the currently selected files from the Finder, as so:

on run
tell application ""Finder"" to set sel to selection
open sel
end run
on open the_files
repeat with i from 1 to (count the_files)
try
set posix_path to POSIX path of (item i of the_files as alias)
if posix_path ends with ""/"" then set posix_path to ¬
text 1 thru -2 of posix_path
try
do shell script ""ln -s "" & quoted form of posix_path ¬
& "" "" & quoted form of (posix_path & "".sym"")
on error
try
do shell script ""ln -s "" & quoted form of posix_path ¬
& "" "" & quoted form of (posix_path & "".sym"") with administrator privileges

end try
end try
end try
end repeat
end open

You could also edit [application]/Contents/Info.plist to add

<key>LSUIElement</key>
<true/>

Just before the last </dict>. This would mean the app would run in the background, and wouldn't come to the front when you clicked on it."

Also, in Snow Leopard where SymbolicLinker doesn't work, you can create a Service with Automator to do either the Terminal command or AppleScript to create a symbolic link.

"One more AS:

tell application ""Finder""
repeat with f in (get selection)
set p to POSIX path of (f as text)
set p2 to POSIX path of (desktop as text) & name of f
do shell script ""ln -s "" & quoted form of p & "" "" & quoted form of p2
end repeat
end tell"
