Magniferous Monks,

Related to another thread, I need to do simple pattern matching and replacing on a file in binary mode (because its a binary file!).

I'm looking for, for example, '77777'(decimal), which is '37 37 37 37 37'(hex), or '0010 0101 0010 0101 0010 0101 0010 0101 0010 0101' (binary).

How does one construct a simple pattern matching and replacing regex in binmode?

Another wrinkle - in binary files, is there sucha thing as 'lines' requiring that we worry about matching over two lines?

Thanks.
