This seems to be more of "don't paste garbage into a terminal, especially as root." With a sidenote that it might be safer if your custom application command interpreter didn't use > as the prompt character. I note that Bourne shell defaults to the safer % and # characters for the prompt. The # character for root is especially safe.

Also don’t shell script on the fly in a production server that has data of any sort you can’t restore from a backup. It’s one giant game of Russian roulette and eventually the human is going to screw up
