Deletes a list of files. Returns the number of files successfully deleted.
Note: unlink
will not attempt to delete directories unless you are superuser
and the -U flag is supplied to Perl. Even if these conditions are
met, be warned that unlinking a directory can inflict damage on your
filesystem. Finally, using unlink
on directories is not supported on
many operating systems. Use rmdir
instead.
If LIST is omitted, uses $_
.
