How do I create a Macintosh Finder Alias From the Command Line?

Question

I am trying to create a Finder Alias from the command line or from a Python program. I have searched the web[1][2][3] and found this bit of applescript:

$ osascript -e 'tell application "Finder" to make new alias at POSIX file "/Users/vy32/cyber.txt" to POSIX file "/Users/vy32/a/deeper/directory/cyber.txt"'

Unfortunately, it gives me this error:

29:133: execution error: Finder got an error: AppleEvent handler failed. (-10000)

What am I doing wrong?

about your message, try to look at Console.app. May be source file does not exists. This helps me when I try to make Xcode 4.3+ applications visible. I've found working code:

$ osascript -e 'tell application "Finder" to make alias file to POSIX file "/file/to/make/link/from" at POSIX file "/folder/where/to/make/link"'

for example:

$ osascript -e 'tell application "Finder" to make alias file to POSIX file "/Applications/Xcode.app/Contents/Applications/OpenGL ES Performance Detective.app" at POSIX file "/Users/mylogin/Applications"'
