Deletes a list of files. On success, it returns the number of files it successfully deleted. On failure, it returns false and sets$! (errno):
my $unlinked = unlink 'a', 'b', 'c';unlink @goners;unlink glob "*.bak";On error,unlink will not tell you which files it could not remove. If you want to know which files you could not remove, try them one at a time:
foreach my $file ( @goners ) { unlink $file or warn "Could not unlink $file: $!";}Note:unlink will not attempt to delete directories unless you are superuser and the-U flag is supplied to Perl. Even if these conditions are met, be warned that unlinking a directory can inflict damage on your filesystem. Finally, usingunlink on directories is not supported on many operating systems. Usermdir instead.
If LIST is omitted,unlink uses$_.
