I have a two lines of code both intend to perform the same task.
Both of which try to delete a certain file. However when I use the unlink command the file does not get deleted. When I use the "rm" system command, the file gets deleted. Any ideas as to why the "rm" would behave differently than the unlink command?

unlink zzz

unlink
link(1M) System Administration Commands link(1M)NAME
link, unlink - link and unlink files and directories
SYNOPSIS
/usr/sbin/link existing-file new-file
/usr/xpg4/bin/link existing-file new-file
/usr/sbin/unlink file
DESCRIPTION
The link and unlink commands link and unlink files and directories. Only super-users can use these commands on directories.
Use link to create a new file that points to an existing file. The existing-file and new-file operands specify the existing file and
newly-created files. See OPERANDS.
link and unlink directly invoke the link(2) and unlink(2) system calls, performing exactly what they are told to do and abandoning all
error checking. This differs from the ln(1) command. See ln(1).
While linked files and directories can be removed using unlink, it is safer to use rm(1) and rmdir(1) instead. See rm(1) and rmdir(1).
/usr/xpg4/bin/link
If the existing file being hard linked is itself a symbolic link, then the newly created file (new-file) will be a hard link to the file
referenced by the symbolic link, not to the symbolic link object itself (existing-file).
OPERANDS
The following operands are supported:
existing-file Specifies the name of the existing file to be linked.
file Specifies the name of the file to be unlinked.
new-file Specifies the name of newly created (linked) file.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of link: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
