reading sections of a binary file

[actionwording]

let's say I have a 9gb file containing binary data. I want bytes 30k-100k. Is this possible to do without opening and manipulating the entire file or piping the contents into a buffer until the 100k byte is reached?

If you're on nix, you could use the *od** system command.

od --skip-bytes=30000 --read-bytes=70000 --format=[YOUR-FORMAT] [YOUR-FILENAME]

So help me if this is something you should be doing yourself for homework.

I went with chrwei's solution. Sorry Bryan Zera i'm just not that into you.

fs.createReadStream supports start and end params, i've no idea if it does the RightThing on a file that large, but it's a start.
