hardlinks.vs.symlinks

Hardlinks vs Symlinks. 

Create hard links by default, symbolic links with --symbolic.


Hardlinks

```
$ln target_file link_name
```
When creating hard links, each TARGET must exist.  Symbolic links
can hold arbitrary text; if later resolved, a relative link is
interpreted in relation to its parent directory.

Symlinks (symbolic links)

When is about symlinks, each destination (name of new link) should NOT already exist.
Create symbolic links with option -s
```
ln -s /path/to/file /path/to/symlink
```
Delete links: `ulink link`
