You understood the question correctly and your output is quite good also, but I'm facing this issue while run. One thing more I want this output in a separate output file, please change the code accordingly.

Can't locate Data/Dump.pm in @INC (@INC contains: /usr/local/lib64/per
+l5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/per
+l5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at script3.pl lin

Code I am trying to run is 

#!/usr/bin/perl;
use strict;
use warnings;
use Data::Dump qw(pp);

open(FILE, "<x.log");
my @array = <FILE>;
close(FILE);

open(FILE, "<y.log");
my @array1 = <FILE>;
close(FILE);

my @array =<<'EOF' =~  m/(^.*\n)/mg;
EOF
my @array1 =<<'EOF2' =~  m/(^.*\n)/mg;
EOF2

@array  = map{/^.*(mti_clk_chk:.*\n)/;$1;}@array;
@array1 = map{/^.*(mti_clk_chk:.*\n)/;$1;}@array1;

## just print these arrays out so that we can see how to compare them?

my $n=1;
foreach (@array) {print "A$n) ",$_; $n++}

print "===============================\n";

$n=1;
foreach (@array1) {print "B$n) ",$_; $n++}

## Make hash tables of the 2 records
## regex could be better - not the point here.. just a quick demo of a
+n approach..

my %A = map{/mti_clk_chk:(?::main :|INFO:)?\s*(.*).*\s*T=(\d+)$/;$1 =>
+ $2}@array;
my %B = map{/mti_clk_chk:(?::main :|INFO:)?\s*(.*).*\s*T=(\d+)$/;$1 =>
+ $2}@array1;

#print only common values in sequential order of file A
print "\n********************************************\n";
print "Common Text descriptions with A and B T values:\n";
print "********************************************\n";

foreach my $mti (map{/mti_clk_chk:(?::main :|INFO:)?\s*(.*).*\s*T=(\d+
+)$/;$1}@array)
{
    if (exists $B{$mti})
    {
        print "$mti T(a)=$A{$mti} T(b)=$B{$mti}\n";
    }
}
