Soft Links or Hard Links

Links allow multiple filenames to point to the same data.

Type	Description
Soft Link (Symbolic Link)	Shortcut to another file; can point to directories; breaks if target removed
Hard Link	Exact reference to file data; only for files on same filesystem

Command	Description
ln -s target linkname	Create soft link
ln target linkname	Create hard link
ls -l	Identify links (soft links show → target)

Example:

ln -s /var/log logs

This creates a shortcut named logs.
