Maybe you should try to fix up the regex? use re 'debug';

I created a sample script and used re 'debug',I really couldn't understand the output ...

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use re 'debug';
my $file= "//depot/asic/msmshared/users/QTVOEMDrops/7600/3555473R/qtv/
+player/audioplayer/audiocmx.cpp";
my $update_p4where=`p4 where $file`;
#print "$update_p4where";
my $update_p4filelog=`p4 filelog $file`;
print "$update_p4filelog\n";
my $update_base_branched_p4path = $update_p4filelog =~ /branch\sfrom(.
+*\/(.*))\#\,(\#\d+)$/xmsg;
print "$update_base_branched_p4path\n";

You don't have anything in your regex that would match the 1.

Thanks for pointing that out,now when I try to print it,I see a "1" getting printed,looks like its printing the number of times it matched,where am I going wrong?

 /branch\sfrom(.*\/(.*))\#\d+\,(\#\d+)$/xmsg;
