Hello everyone,
I would like to filter and search for files in my curr dir where the blocks used by those files are over a certain number (i.e. 30), when I try this command
find . -name "c*" -size +30 -exec ls -ls {} \;
I get a list of files, the first column is the block size, right?

Hi all,
We dont have access to aix source code and i have a doubt.
The flag SC_NO_RESERVE, is it got to do anything with the failover?
If the flag is set the paths are going to failed state. If flag is not set everything comes up fine after failover.
Thanks in advance for helping

Hey, all!
Why is the "human readable" flag changing the behavior of du? And while I'm at it, can you make du only look at files, not directories. I often find myself wanting to find the largest file(s) in a dir or vol. Using 'find' itself, it seems you have to at least be able to guess the size of... (2 Replies)

io::async::pid
IO::Async::PID(3pm) User Contributed Perl Documentation IO::Async::PID(3pm)NAME
"IO::Async::PID" - event callback on exit of a child process
SYNOPSIS
use IO::Async::PID;
use POSIX qw( WEXITSTATUS );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $kid = $loop->fork(
code => sub {
print "Child sleeping..
";
sleep 10;
print "Child exiting
";
return 20;
},
);
print "Child process $kid started
";
my $pid = IO::Async::PID->new(
pid => $kid,
on_exit => sub {
my ( $self, $exitcode ) = @_;
printf "Child process %d exited with status %d
",
$self->pid, WEXITSTATUS($exitcode);
},
);
$loop->add( $pid );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits.
For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data
to and receiving data from it.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_exit $exitcode
Invoked when the watched process exits.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
pid => INT
The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object.
on_exit => CODE
CODE reference for the "on_exit" event.
Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object.
METHODS
$process_id = $pid->pid
Returns the underlying process ID
$pid->kill( $signal )
Sends a signal to the process
