how to read the formatted data from the file?

[vikingy]

Hi all,

There is a file  created likes this:

   open File ">file.txt" or die $!;
   foreach .. <..> {
      printf File "%5d %11.2f\n", $data1,data2;
   }
   close File;

and my question is, how to read these data follow the same format as "%5d 
%11.2f' from this file again?
    thanks in advance!
