Putting script in background

perljunky has asked for the wisdom of the Perl Monks concerning the following question:

I have a need to put the script I am running in background. However as soon as I fork the child is getting the INT signal sent to it and the &INT_handler is kicking in. I am sure I havent coded it correctly. Can you help please?

#!/usr/bin/perl
# Put script in background but wait a few before exiting
sleep 10, exit if (my $pid = fork);

# Signal handling routines
$SIG{'INT'} = &INT_handler;
$SIG{'QUIT'} = &QUIT_handler;

# rest of child code below including sub INT_handler

Hard to tell considering the lack of markup on your code sample, but it would appear you're calling `INT_handler` and setting `$SIG{INT}` to it's return value. You want `\&INT_handler` to return a reference to your sub instead there. Update: And there was markup. Huzzah, much better. :)	[reply] [d/l] [select]
