What signals will cause a Perl program to stop running if their %SIG entries are not explicitly set?
The answer is platform dependent. To see the default behavior of each signal on your own system, download the
Signals::XSIGmodule (you don’t need to install it) and run the programspike/analyze_default_signal_behavior.pl(with no arguments). Or just download and run the script from here.Note that some signals cannot be trapped by your program even if you do install a
%SIGhandler. This is also system dependent but usually includes at leastSIGKILLandSIGSTOP.
