I tried doing the following --- 
my($url,$name,$text,@lines,$key,$value,$line);
    my($Docs) = "temp.txt";
###start of comment
#temp.txt is of the format ---
#name1@url1@text1
#name1@url1@text1
#name1@url1@text11
#name2@url2@text2
#name2@url2@text21
#name3#url3@text3,etc...
##end of comment

    my %file_hash;
    
    open (FILE, $Docs);
    @lines = <FILE>;
    close FILE;
    
    foreach $line (@lines)
        {
        chomp($line);
        ($name,$url,$text) = split('@',$line);
        chomp($url);
        $key = $url;
        $value = $line;
        $file_hash{$key} = $value;
        }
    open (OUT, ">$Docs");
    for my $key (keys %file_hash)
        {
        print OUT "$file_hash{$key}\n";
        }
    close OUT;
    }

my guess to what is happening here is that since I am using the hash - i am actually storing the last match to the $key and I am not getting what I want as the OUT file
the OUT file that I need is ---
name1@url1@text1
name2@url2@text2
name3#url3@text3,etc...
thank you for your patience........
