Yep, any LBS will sell you it by the metre. It's platic coated but flexible wire on the inside. Better ones are spiral wound.
If you ask nicely they may cut it to size with the right tool that doesn't foul up the ends.
You will also need a new inner cable as you'll have to remove it and it will most like be damaged.

Do make sure you get the right one - gear cable outer not brake cable outer in your case.
Gear cable outer is designed not to compress, so that the measured amount of inner cable pulled by the ratchet mechanism is exactly the amount that the derailleur is pulled by. It's basically parallel wire strands formed into a tube and plastic coated.
Brake cable outer on the other hand needs to be stonger, because you can pull the brake lever a hell of a lot harder than the shifter does.
It's essentially a plastic-coated long spiral wire, like a spring, so it compresses a little but that's not a problem with the brakes.
If you used brake cable outer for the gears, you'd just get slightly cr*ppy shifting (which might be OK as a get-home-from-middle-of-nowhere fix if touring somewhere really remote).
But if you used gear cable outer for the brakes, you'd risk it failing, splitting, and your brakes failing catastrophically...

You might be better off getting a new set of both really, inners and outers, so long as you have the tools to cut both..... if not see what the LBS recommends..
Me, I'd replace both inner and outer, but I have the tools !

Spiral wound outer cable is usually brake outer and may not be compatible with your index gear system. Outer wire for index gears consists of linear strands as they don't compress and allow more accurate shifting. ShimaNO have made index gear int he past but it is normally sold in fixed lengths, pre-compressed with ferrules securely fastened at each end.
