That's probably the best solution if you're on Unix, Linux or OS X.

Not sure if comm(1) is available by default on Windows, however.
It's been a while since I've worked on one of those systems.
I'm pretty sure you can get comm(1) by installing Cygwin, the MKS Toolkit,
or Microsoft's Subsystem for Unix-based Applications (SUA).
But if this is the only Unix-like task the OP needs done,
it might not be worth the trouble.

In general, whenever possible I prefer to use external commands
rather than plugins. If I wanted my editor to do everything itself,
I'd be using emacs. ;)
