Re: Remembering values from multiple condition 'if'

When in doubt, rethink code structure... ;)

  for my $file ( qw/ file1 file2 file3 file4 ) {
     if( -e $file ) {
        unlink($file) || print STDERR "error unlinking $file: $!\n";
     }
  }

There's really no point in testing to see if an unlink might succeed before attempting it. Just do the unlink: `unlink qw/ file1 file2 file3 file4 /;` [download] Although your way is cooler if you want clean error messages if something goes wrong. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]
