Hi Experts,

As mentioned in my pervious posts, i have condition-file which contains data as...

condition-file
---------------
K    01
J    02
I    03
H    04

i have input files where i have stored all the files in a array called @filelist, which may be file1,fie2,....filen.Each file contains record like...

file1
-------
K,01,data,japan,jung,kcika,Kisjl,01234
J,02,thaja,China,cunk,Jksb,Yjski,23456

i need to take first element from the condition-file and need to check if it exists in all files exist in @filelist for example, i have taken the first element from condition-file, K and will check if this exists in each file in @filelist check in file1, if exists print the line to output text file, check file 2 and do the same till filen

i have code which is taking more than 1 hour.Although it works fine, it takes very long time, 30 min to 1 hour. I also tried following Perl script 

foreach my $file_name (@array) {
    open FILE, "$file_name" or die "File not exists";
    while ( my $line = <FILE> ) {
        my ( $field1, $field2 ) = split /\,/, $line;
        if (exists $records{$field1}) {
            $field_2 = $records{$field1};
            if( $field2 eq $field_2 )
            {
                print OUTPUT $line;
            }
        }
    }
}

I was wondering if someone could suggest a solution
