Sure. Nothing wrong with that. The advantage of trapping a signal
other than those that terminate the program is that you get more
opportunities to use it. IOW, you can send USR1 and examine whatever
properties of the program you like without actually stopping it.
It sounded as if the OP might be interested in this because they
mentioned tee earlier.
But my point was that prodding the program with signals seemed a
better fit than just forcing line buffering.
Cheers,
David.
