Re: array processing

Use a hash. Something like the following


# opening of files etc.

my %users = ();


while ($line = <errlog>) {
    chomp $line;
    next unless ($line =~ /Login succeeded/);
    $users{(split / /, $line)[6]} ||= 1;
}

foreach (sort keys %users) {
   print LOGINF $_, "\n";
}

# closing fhs etc

This is untested.

NB: consider using lexical filehandles.

I preferred a regex over a split since we are only getting the user out of the data and we don't need any of the other values. You can increment the user's login count in one line inside the while loop: `$users{$1}++ if $line =~ /Login succeeded. User: (\w+)/i;` [download]	[reply] [d/l]
