Hiya,
Recently I've run a few scripts in the foreground, but have realised later they should of been better nohup'd and placed in the background. I understand how to change a foreground job into a background one, but how would put the job into the nohup state?
Thanks (1 Reply)

Hello,
I am running a shell script whose execution often takes several hours to complete. Is there way I can get some kind of status update as the job is running? Something as simple as the start and the current time stamp.
Thanks,

Hi All,
I have a scenario where I am executing some child shell scripts in background (using &)through a master parent script.
Is there a way I can capture the exit status of each individual child script after the execution is completed. (2 Replies)
Is there a way to suspend (TSTP?) a job that is running in the background, _without_ first bringing it to the foreground and inputting Ctrl-Z from the keyboard?
IOW, something similar to issuing the shell's bg builtin command on a job ID to resume a job that is suspended in the background,... (2 Replies)
Hi,
Should the user jobs specified in crontab be running in background?

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
