link, unlink - Creates an additional directory entry for an existing file
SYNOPSIS
link file1 file2
unlink file

Interfaces documented on this reference page conform to industry standards as follows:

Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The link command performs the link() system call to create an additional directory entry for an existing file, file1. In effect, the
underlying file then has two names, file1 and file2 (either of these arguments can be a pathname). The old and new entries share equal
access rights to the underlying file.
The unlink command performs the unlink() system call to remove a link to file created by link. The unlink command removes the directory
entry specified by the file parameter and, if the entry is a hard link, decrements the link count of the file referenced by the link.
You should be familiar with the link() and unlink() system calls before you use these commands.
The link and unlink commands do not issue error messages when the associated system call is unsuccessful.
NOTES
The link and unlink commands cannot be used to link and unlink directories.
EXIT STATUS
The link and unlink commands both exit with the following: The link() or unlink() system call succeeded. Too few or too many arguments
specified. The link() or unlink() system call failed.

I have some files that appear to have no inode numbers. To complicate the matter, the filenames have UTF8 (I think) characters.
I am trying to delete them. In fact, and this might make things easier, I'm trying to delete their parent directory.
