In the above code which is actually given in the node, you are assigning a value to $distrib_dir = $FindBin::Bin; then you are declaring the saame variable as follows my ( ${birt_dir}, ${distrib_dir}, ${hostname} ); which will make the $distrib_dir as empty. Because I could see the you are using $distrib_dir in getting the value of $tar_dir.
