The mntServer.ksh script contains:

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.
Is there any other way to watch completion of any, not related process (at least, a process, owned by the same user?)
I need to start a background process, witch will be waiting... (2 Replies)

Hi
I am writing a bash script on Solaris, that should take n arguments, either appended to the script or taken as output from the last command (similar to grep). What I don't want is that the script waits for user input. In other words:
Possibility 1:
script.sh arg1 arg2 arg3 ...Possibility... (4 Replies)
Hi,
I was wondering if pipes ("|"), or rather the command that follow them, know when they're supposed to wait for all the data?
For instance, if you take this:
cat my_file | sort | uniq
for uniq to work well, it needs to have rows sorted, but for lines to be sorted properly, it needs... (5 Replies)
Hello,
On a HP-UX 10.20 server I've executed something similar to this command:
# echo 'selall;info;wait;infolog;view;done' | /usr/sbin/cstm
But it returns sometype of "argument list too long" error.
I suppose there is a way to fix it by using xargs but I can't figure it out.
Any... (7 Replies)

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.
