Hash is appending old and new data

[theroninwins]

I know the title is not what it should be but I can't think of a better one so please feel free to rename it.
Anyway here is the problem:

    open(OUT, "serlist.txt");
    open(OUT2, "desclist.txt");
    open(OUT3, "namefile.txt");
    my @outlist;
    while (<OUT>)
        {
        my %hash;
        my @temp = split(/;/,$_);
        $hash{'file1'} = $temp[0];
        $hash{'file2'} = <OUT2>;
        $hash{'file3'} = <OUT3>;
        
        #delete Return
        foreach (values %hash)
            {
            $_ =~ s/\n//gi;
            }
        push(@outlist,\%hash);
        print @outlist;
        }
    close(OUT);

What happens is that the hash is not only adding the new lines it learns after running through the text file but adds all he did before just as well. Maybe an examples helps at this point:

As you can see the first 3 lines are the first 3 in the second section and then it repeats it again adding the new line that comes. Then it reapeats the first and second section, and then repeats it again appending the new stuff. The problem is that thjere are about 300 components that need checking and that is goes way over 400MB where only the last bit is needed so to say. And the IPs are also wrong on the repetitions. So how can i do it that the hash only appends the new line(s). Sorry for that explanaition but i can't really do it better this time.

In a hash, Keys are what that is unique. Not the values.

Some of the nodes which may give insights related to your query.

• Adding or removing keys while iterating over a hash
• Changing the keys of hashes in arrays
• Multiple identical keys in a hash.

It seems to me (without a thorough understanding of what you're actually doing) that the problem is you're declaring @outlist outside of the loop, then for every line in OUT you're pushing more data onto @outlist and then printing the whole thing. If you move the my @outlist inside the while where you declare your hash, or if you move the print @outlist outside of the loop, you should only get each item once.
