Hi Monks, I have a file that contains some employee information .. sort schedulling file. I need to update the file and sechdul more people however , I wana make sure I am not sechdulling the same person based on thier number the data file looks like this : 
data
----
Loc     num     name    age     car     $$
817     09      Sam     99      TU      300
444     11      Ram     88      CM      7
111     3       Kin     8       RT      88

so the key will be the num ,if the employee number exists then error. I was doing the following: 

my $empNUM;

open(DATA, "data") or die ; 
open(UPDAT, ">updated") or die;
while(<DATA>)
{
my @line = split(/ /, $_);
foreach $line (@line)
{
if ($line[2] eq $empNum){exit 0;}
}
}end loop
print UPDAT $details;
close(DATA);
close(UPDAT);

since I am new to perl , I don't think this is the wise way of doing it , any advice on doing this? thanks
