If you rename the target file or directory, the symlink will fail. A symlink is just stores the alternate path information.

An Alias can generally survive renaming the target file and even find the file if you move it to a different Folder within the same file system.Ī symlink is implemented in the file system driver layer (very deep into the operating system, just above the physical storage device). An Alias can have its own icon, it can store network file system connection information, along with the username need to mount a network accessed file system.

While an Alias and a symlink have similar behaviors at the 10,000 foot level, they are implemented in different layers of the software stack, and have some fine-grained detail differences.Īn Alias is a GUI file manger abstraction that is only functional when used by GUI apps that work with the GUI frameworks and access files via the GUI file manager. The Finder does NOT create symlinks! The Finder can ONLY create an Alias In finder, when you make a alias or symlink The end result is still going to be your house, and if you are not home, none of your friends are going to find you sitting on the porch, no matter what route they took to get to your house. Think of it as being able to give your friends 2 different routes to your house when they start from the same point. If you delete the symlink entry from the directory where the symlink lives then you delete the symlink (aka the file system special entry. There was only ever one copy of the file when using symlink. If you delete the file in the folder, you deleted the file. You DO NOT create a new folder, you just have a different way to point to the exact same folder, or if the symlink is pointer to a file, an alternate route to that file.
if you delete the file in the symlink folder, the original file is also deleted.Ī symlink is just a special file system entry that causes the path lookup to re-vector (take a left turn) and take an alternate route to the item you point the symlink at. If the target file/folder is moved the symbolic link will no longer work.Files in a folder which you create as a symlink are displayed as same as original files in Finder. You can see the symbolic link pointing to the target directory.

You create a symbolic link on the command line using the command ln with a -s parameter like so: ln -s target-file-folder alias-file-folder It is however different then a regular alias created in the finder of macOS. A Symbolic or Soft Link is a traditional Unix link to an original file or directory which can reside anywhere on the filing system, the linked file when opened as a file or directory has the same contents as the original and if you edit the linked file or add content to the linked directory it will be as so that you are doing it to the original.
