Is there a feature on OS X that does the same as mklink under Windows 7? It can create symbolic links and hard links.

I have just read about this tool to have Dropbox sync an application folder by combining it with mklink on Windows 7, using a hard link:

How can I achieve this on OS X?

Open /Applications/Utilities/Terminal.app and run ln for a short description, and man ln for documentation.

Example:

ln existing.txt new.txt

For folders, create a symbolic link using ln -s:

ln -s existing new

As per @Scott's comment, these symbolic links work with Dropbox on OS X. Success!


Hardlinks on folders are possible, but difficult and insanely dangerous if you mess it up (they don't like recursion).

I don't know either, but the Windows example uses hard links, not symbolic links. OS X supports hard linked folders since Time Machine has been introduced. Never used it myself though. – Arjan Jan 11 '11 at 16:48
    
@Arjan Thanks for the edit to the question, I just saw it and added to my reply. – Daniel Beck Jan 11 '11 at 16:49

Use a symlink to sync folders outside your Dropbox on Mac OS X (and Linux for that matter). It works fine, and you avoid the whole can of worms that hard linking directories is. See wiki.dropbox.com/TipsAndTricks/SyncOtherFolders – Scott Jan 11 '11 at 16:59
