Thanks once again for your input!

When I try running my script with the following test set , it does not print anything in the output files, instead prints the data onto the screen!

I thought maybe splitting the header and data might help. But as it turns out, I am not going the right way.

The output I get from the script is:

>001.b1 gnl|ti|10009

My script for the same is: 

       ......
        s/^>//mg;
    my ($name) = /^([^\n]+)/;

        if($hash{$name} == 10){
        select FILE1;
        }
        if($hash{$name} == 20){
        select FILE2;
        }
        if($hash{$name} == 30){
        select FILE3;
        }
        }
    #print ">$_";
    my $output = $_;
    print ">$output\n";
