What is Symbolic Link?

A special file that acts as a shortcut pointing to another file or directory in the filesystem.

A symbolic link (symlink) is a reference to another file or directory. Unlike hard links, symlinks can cross filesystem boundaries and link to directories. They are created with ln -s.

If the target file is deleted, the symlink becomes a "dangling" link pointing to nothing. Symlinks are widely used for version management, configuration shortcuts, and library linking.
