The ln command is a standard Unix command utility used to create a hard link or a symbolic link (symlink) to an existing file or directory. [1] The use of a hard link allows multiple filenames to be associated with the same file since a hard link points to the inode of a given file, the data of which is stored on disk.
It can be manipulated using several calls from the C header file linux/debugfs.h, which include: debugfs_create_file – for creating a file in the debug filesystem. debugfs_create_dir – for creating a directory inside the debug filesystem. debugfs_create_symlink – for creating a symbolic link inside the debug filesystem.
A symbolic link contains a text string that is automatically interpreted and followed by the operating system as a path to another file or directory. This other file or directory is called the "target". The symbolic link is a second file that exists independently of its target. If a symbolic link is deleted, its target remains unaffected.
An NTFS symbolic link is not the same as a Windows shortcut file, which is a regular file. The latter may be created on any filesystem (such as the earlier FAT32 ), may contain metadata (such as an icon to display when the shortcut is viewed in Remove links), and is not transparent to applications.
A malicious user can create a symbolic link to a file not otherwise accessible to them. When the privileged program creates a file of the same name as the symbolic link, it actually creates the linked-to file instead, possibly inserting content desired by the malicious user (see example below), or even provided by the malicious user (as input ...
Duplicity works best under Unix-like operating systems (such as Linux, BSD, and Mac OS X), [8] though it can be used with Windows under Cygwin or the Windows Subsystem for Linux. Currently duplicity supports deleted files, full Unix permissions, directories, and symbolic links , fifos, and device files, but not hard links .

Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/realdir pwd -L: Display the current working directory logical path - with symbolic link name, if any. Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/symlinked
