I've got a problem with something I'm currently working on. All that I have needed to use perl for up until now was some pretty basic text manipulating. Nothing too fancy, with the help of some of the monks here, I was able to come out of it great, learning a lot. Now, there is a new problem. I've got a file that is pretty much raw binary data, and an old solution with a ksh script under unix that did this: 
cc=`hd -bx -s 29 -n 3 <"$filename"|tr -d '[ " " ]'|awk '{print $2}'`

In some parts, there is an offset as well, which I understand how to work with. The problem I'm hitting is that I do not know how to emulate this in perl. The HD command on our old Unix machine was set like this: 
hd-- display files in a hexadecimal format
hd [ -format (bx is binary)] [ -s(offset)] [-n (count)] [filename]
tr - translate characters
the -d Deletes all input characters in the input string.

I found this module that had something similar to what I'm trying to do, but I don't understand how to use it. Any help is much appreciated. How do I convert between decimal and binary?
