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