Hi yads25,

Welcome to the Monastery! Make yourself at home.

To accomplish your task, go through perlopentut and perlre. Try some code and if you have any questions, you can come again here.

      Hi yads25,

      Please use <code> tags to wrap the coding parts in your nodes.

      Can you please show us your sample file, so that we can give solutions without assumption.
