SIGNALS
When bash is interactive, in the absence of any traps, it
ignores SIGTERM (so that kill 0 does not kill an interac-
tive shell), and SIGINT is caught and handled (so that the
wait builtin is interruptible). In all cases, bash
ignores SIGQUIT. If job control is in effect, bash ignores
SIGTTIN, SIGTTOU, and SIGTSTP.
