NAME
link, unlink - Creates an additional directory entry for an existing
file
SYNOPSIS
link file1 file2
unlink file
DESCRIPTION
The link command performs the link() system call to create an addi-
tional directory entry for an existing file, file1. In effect, the un-
derlying file then has two names, file1 and file2 (either of these ar-
guments 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.
NOTES
The link and unlink commands cannot be used to link and unlink directo-
ries.
EXIT STATUS
The exit values of the link command are: The link() system call has
succeeded. Too few or too many arguments have been specified. The
system call has failed.
The unlink command always returns 0 (Zero).
