Hi Monks , Can you see the problem with my script , I am trying to add information about students age inside a file as follow:
--- DATA ----
NAME AGE
Sue 22
Sam 34
LUi 43
My script works fine and update the file , however , I don't want to add a duplicte entries in the file so if Sue 22 exists I don't want to add it again , I am checking for that in my script but it is not catching it .
$|++;
use strict;
use Fcntl ':flock';
print "Enter new student's name: ";
chomp( my $student = <STDIN> );
print "Enter new student's number: ";
chomp( my $studentAge = <STDIN> );
open my $fh, '+<', 'students.dat' or die "open failed: $!";
flock $fh, LOCK_EX or die "flock failed: $!";
my $found = 0;
while (<$fh>) {
$found = 1 if /^\Q$student\E$/i;
}
print $fh $student ,"\t" , $studentAge ,"\n" unless $found;
close $fh;
Ok thanks
