I need to check whether the 4th value of second file matcheds with the first files's value
And i have to just save unmatched value in a new file
Below are my trials
use strict;
use warnings;
use Data::Dumper;
our %hash;
my $firstFile = $ARGV[0];
my $secondFile = $ARGV[1];
open FIRST, "< $firstFile" or die "could not open first file...\n";
while (my $line = <FIRST>) {
my @elements = split '\|', $line;
my $col3Val = $elements[3]; # Perl arrays are zero-indexed
$hash{$col3Val} = 0;
}
close FIRST;
open SECOND, "< $secondFile" or die "could not open second file...\n";
while (my $line = <SECOND>) {
my $col0ValFromSecondFile = $line;
if (defined $hash{$col0ValFromSecondFile}) {
print "$col0ValFromSecondFile Matched";
}
else {
warn "We did not locate $col0ValFromSecondFile in hash table for second file's Col2 value...\n";
}
}
close SECOND;
I suspect a big flaw in the hash ,which iam not ablt to find.
Please help me , thanks in advance
