=over =item unlink LIST X<unlink> X<delete> X<remove> X<rm> X<del> =item unlink Deletes a list of files. On success, it returns the number of files it successfully deleted. On failure, it returns false and sets L<C<$!>|perlvar/$!> (errno): my $unlinked = unlink 'a', 'b', 'c'; unlink @goners; unlink glob "*.bak"; On error, L<C<unlink>|/unlink LIST> 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: $!"; } Note: L<C<unlink>|/unlink LIST> will not attempt to delete directories unless you are superuser and the B<-U> flag is supplied to Perl. Even if these conditions are met, be warned that unlinking a directory can inflict damage on your filesystem. Finally, using L<C<unlink>|/unlink LIST> on directories is not supported on many operating systems. Use L<C<rmdir>|/rmdir FILENAME> instead. If LIST is omitted, L<C<unlink>|/unlink LIST> uses L<C<$_>|perlvar/$_>. =back
