It seems like you are newbie to UseNet as well. Please read

Posting the exact same request several times is considered rude and
unacceptable.

That isn't what you asked in either of your threads.

If you change the question, the answer is likely to change.

Many observers may choose to wait for the oscillations to damp to the
point where there is one target that isn't a moving target.

If you take more care in composing your question, you will get
much more rewarding responses than if you just spew out the
first thing that comes to mind.

Hello,

open()..this is where i am facing the problem

I think you are confused as to the purpose of the system command.
The system command runs the command and returns the exit status
whereas the backticks (``) runs the command and returns what it
sent to STDOUT.
What you want to do is run the command and grep for the line that you
want. Something like:
---------------
use strict;
use warnings;
my @out = grep {/^02/}`dir`;
^^^^^^^^^^^^^^^^^^^^^^^
print @out;

What this does is
run the dir command (capturing the output) feeding it to grep
where it will match any line that contains the string 02 at the beginning
of the line. This is put into the @out array.

I hope this helps.
