if statement - Perl: foreach line, split, modify the string, set to array. Opendir, next if files=modified string. Unlink files -

i'm having issues following block of code: $output netstat -lnt | grep ":::60". section under comment #create filename format

my @lines = split /^/, $output; foreach $line (@lines) {  ($garb, $long_ports)  = (split /\s*:::\s*/, $line);  #get last 2 digits of 60xx port number  ($garb2, $ports) = (split /60/, $long_ports);  #split values numbers 0-9 correct filename format if ($ports < 10) {   ($garb3, $ports2) = (split /0/, $ports);  #add 0 since 0 port split empty string if (length($ports2) == 0){   $ports2 = "0$ports2"; }  #create file name format @locked_ports = ".x$ports2-lock";  } }  %h = map {$_ => 1 } @locked_ports;  #open /tmp , find .x*-lock files not match locked_ports  opendir (dir, $tmp ) or die "error in opening dir $tmp\n";  while (my $files = readdir(dir)) {    if (exists $h{$files}){    next}    unlink $files;  }    closedir(dir); 

i've tried:

#create file name format @locked_ports = ".x$ports2-lock";  } }  #open /tmp , find .x*-lock files not match locked_ports  opendir (dir, $tmp ) or die "error in opening dir $tmp\n";  while (my $files = readdir(dir)) {    next if $files =~ @locked_ports;    unlink $files;  }    closedir(dir); 

and:

#create file name format $locked_ports = ".x$ports2-lock";  } }  #open /tmp , find .x*-lock files not match locked_ports  opendir (dir, $tmp ) or die "error in opening dir $tmp\n";  while (my $files = readdir(dir)) {    next if $files =~ $locked_ports;    unlink $files;  }    closedir(dir); 

each time error similar to: global symbol "@locked_ports" requires explicit package name, global symbol "$locked_ports" requires explicit package name

how can have while "next" on filenames equal lines of locked_ports?

any appreciated.

thanks.

my scopes variable inner-most block (curlies) in located.

{    $foo;    ... }  # $foo not accessible here. 

the block ends on line after 1 create variable. move variable's declaration has sufficiently large scope.
