[sandeepda]

Thanks Athanasius; I am trying it to make generic I am getting this output as array @outputarray also output is synamic the name and post can change How can i parse this where outputarray[0]=name ip port outputarray[0]=------------------------------------ outputarray[0]=http-listener-1 * 6712

 
name          ip   port 
------------------------------------ 
http-listener-1 * 6712 
http-listener-2 * 8709

Hello again sandeepda,

I’m sorry, but I don’t understand what you are asking.

The only thought that comes to mind is that you may be unfamiliar with Perl’s special DATA filehandle. But I used that only for convenience. If you already have the data in an array, you would adapt the opening of my script as follows:

for (@existing_array)
{

On the other hand, if the data is in a file (named, say, “ports.dat”), then you would begin like this:

my $file = 'ports.dat';
open(my $fh, '<', $file) or die "Cannot open '$file' for reading: $!";

while (<$fh>)
{

If this doesn’t answer your question, please explain what you are asking with your version of the code together with sample input and the output you want. See How do I post a question effectively?

Hope that helps,

Sorry I am beginner in perl just starting hence if there are mistake please oblige. Here is the problem I am executing subroutine in perl script it returns me output dynamically in array format @outputArray

outputarray[0]=name  ip  port 
outputarray[1]=------------------------------------ 
outputarray[2]=http-listener-1  *        6712
outputarray[3]=http-listener-2  *        4743

I can also get the output array as like below also if i want

outputarray[0]=http-listener-1  *             6712
outputarray[1]=http-listener-2  *           4743

I want to write a subroutine which will check whether port exists and if exists returns me true and the listener name if not it returns me false and null getListenerName($porttobeChecked) This subroutine returns me the name of the listener if i pass a port. Eg: If $porttobechecked=6712 I want to return an array a[0]=TRUE and a1=http-listener-1(listener name) If port to be checked = 4516.I want to return an array a[0]=FALSE and a1=null .Help required

Hello sandeepda,

"I want to write a subroutine which will check whether port exists and if exists returns me true..."

I think your question has really been answered in this thread How to check whether my array contains element x started by you..Please check.
Except you have something else in mind..
