Getting a value

[Sakthi]

I am getting a string value from a function .A variable is exist by that
string value. Need to print the value using the second variable!
Example:

my $log_dir="hello";

my $name=function1(); // $name has value "log_dir"

I want the output as "hello" using the "name" variable. Is that possible?

TIA

Yes.

Below is a quick hack that I think does what you want to do.

--8<--8<--8<--8<--8<--
#! /usr/bin/perl -w
use strict;

my $log_dir="hello";

sub function1() {
return "$log_dir";
}

my $name = function1();
print "$name\n";
-->8-->8-->8-->8-->8--

Hi,

you've tried those:

print $$name
print ${$name}

they should work both
