-s	Create a shell that reads commands from standard input and sends shell messages to the standard error channel.
-i	Create an interactive shell; like the -s option except that the SIGTERM, SIGINT, and SIGQUIT signals are all ignored. For information about signals, consult Chapter 12, "Systems Programming."
