symbolic link to file, but not to dir

Hello!
I try to use your script, but I run into unpleasant problems.

I created a .dotfiles repository in $HOME.
The file structure is approximately as follows:
```
- .dotfiles
-- .config
--- i3
---- config # i need only this file
```
In my $HOME there is also a .config folder and it contains many files of third-party programs, for example chromium which I would not like to upload. There are many such folders and they constantly appear.
I created a file in the .dotfiles/.config/i3/config repository and reckon that a symbolic link will be created on this file, but your script tries to create the entire .config directory. How to fix it?

Maybe you can check: if is dir -> recursive search all files and create symbolic link
