Re: INT signal kills process run with expect, when $SIG{'INT'} is set

It's actually kills even w/o Expect. Code below is killed with ^c too:

require Expect;
use strict;
$SIG{'INT'}=sub {print "Al Bundy rules!\n";};
sleep 10000;

The prcess lasts until 1st ^c.

On many platforms sleep will exit on any signal, including SIGINT. You need to place it in a loop. For example: `use warnings; use strict; $SIG{'INT'}=sub {print "Clive Darke rules!\n";}; while (1) { sleep 10000; }` [download]	[reply] [d/l]

It doesn't kill the process, handled signals interrupt `sleep`. If they didn't, the handler wouldn't get to run. See Re: fork() doesn't care about my sleep()? for how to make sleep uninterruptible. The OP didn't (visibly) use a `sleep` in the process that has a signal handler, so this isn't (likely to be) the OP's problem.	[reply] [d/l] [select]
