static evals from list of FENs?

[zenpawn]

Is there a way to feed Stockfish (or any engine) a list/file of FENs and get back its static evaluations, perhaps via one of the GUIs?

Stockfish 7 would output its static eval by the command eval.
So this can be done easily by a script by executing the engine send the fen/epd issue the eval command and extract the total evaluation value.

Other engines have different commands to output its static eval.

Yeah, that's always an option (writing it yourself), but figured it might already exist.
