12.8 unlink: Remove files via the unlink syscall

unlink deletes a single specified file name. It is a minimalist interface to the system-provided unlink function. See Deleting Files. Synopsis: It avoids the bells and whistles of the more commonly-used rm command (see rm invocation).

     unlink filename

On some systems unlink can be used to delete the name of a directory. On others, it can be used that way only by a privileged user. In the GNU system unlink can never delete the name of a directory.

The unlink command honors the --help and --version options. To remove a file whose name begins with ‘-’, prefix the name with ‘./’, e.g., ‘unlink ./--help’.

An exit status of zero indicates success, and a nonzero value indicates failure.
