G'day rekhasri,

Welcome to the monastery.

Take a look at the push function.

I can't see anywhere in your code where you're adding anything to an array. However, what you've written is rather difficult to read: take a look at Markup in the Monastery.

You probably want something like:

my @agent_ids; # outside logfile reading loop ... if (...) { ... push @agent_ids, $agent_id; }

    I forgot to add that array line in my code. Now I have added that line in my first question. Sorry for the inconvenience.

      Well, it's not an inconvenience, but that does now highlight where you're going wrong.

      Declare your array outside of whatever loop iterates over your logfile and replace my @array=$agent_id; with a push statement, as I indicated.

      -- Ken

        if($line =~ /^.*:agent_id=>(.+?),/){ # Calls count based on call type my $agent_value=$1; my $agent_value=~s/\"//g; push @agent_ids, $agent_value; print Dumper\@agent_ids; }

        Before while loop I have declared the @agent_ids and then added the push function with array and scalar variable.

        While printing the @agent_ids variable it printed the undef in array.

        I don't know why it is printing the undef values instead of exact values.
