Help required on the script

[Mazhar]

Hi Folks,

I have a script written which will read a file and analyse the input and
depending on the input i should make different files for the same.

The code is,
#######################################
open(FILE,"< $file_name");

while(<FILE>)
{
    $line=$_;

    if($line= /(.*)(Unique Column name)(.*)/ ) (This Unique Column Name will
be present in the second position Seperated by a Space Delimet)
    {
    }
}
##############################################

How can i check the existence of Unique set at the 2nd Position.

Thanks in Advance

regards
Mazhar
