POSIX states: "Signals that were ignored on entry to a non-interactive shell cannot be trapped or reset, although no error need be reported when attempting to do so. An interactive shell may reset or catch signals ignored on entry." http://www.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#trap I see no bug - bash is within its rights to pretend that an inherited ignored SIGINT has no trap setting, seeing as how the user cannot modify that through any use of trap. That is, 'trap -p' is designed to output the text that will restore traps to their normal state, but since there is no way to change the state of SIGINT from being ignored, there is nothing needed in the output. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
