If you receive it via a streaming port, you can also use {packet,4} as an option, which will automatically break the binaries into appropriate lengths.

Also, one of the more unusual (but awesome) bits of binary pattern matching is something like this:

Interestingly, you can also do it like this, to match chunks in a large binary:
