The link command performs the link() system call to create an addi‐
tional 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 asso‐
ciated system call is unsuccessful.

or unlink() system call succeeded. Too few or too many arguments spec‐
