I'm using growisofs to write DVD, e.g.
$ growisofs -Z /dev/dvd -V "Personal Data, `date +"%b, %d %Y"`" -R -J /mnt/d/*
How can I test whether data was written correctly? md5sum or so? (0 Replies)

I have a ksh script that currently moves a day's worth of log files (about 15,000) files to a different directory. The issue is that about 100 of these files are still open for write when this happens. I need an efficient way to ensure that these files aren't open without doing an lsof on each... (7 Replies)
Hi all
i want to know what are the logs we need to check when the server is down and how to resolve to make server UP? please help me with this (8 Replies)
I know how to check if any file has a unix process using a file by looking at 'lsof <fullpath/filename>' command.
I think using lsof is very expensive. Also to make it accurate we need to inlcude fullpath of the file.
Is there another command that can tell if a file has a truely active... (12 Replies)
Hi,
Yesterday I installed and configured logrotate on my Debian machine. I was expecting this to run at 06:25 in the morning and it actually did. All my old logs were compressed and zipped but the new logs were all with size equal to 0 bytes. Processes, while still running ok, they were not... (2 Replies)
I have nearly 25+ tail commands which we need to verify the logs if there is any errors on current or previous date with time. I need this to be automate and send email to me with details. Please help me on this. (5 Replies)
Hi there! I'm developing a program that allows the user to open and edit files using both an editor and the terminal. Once the user has finished editing the file an update is sent to the logbook that compares the file before and after it was edited - this can only be done if the file is closed (I... (23 Replies)

io::async::timer::absolute
IO::Async::Timer::Absolute(3pm) User Contributed Perl Documentation IO::Async::Timer::Absolute(3pm)NAME
"IO::Async::Timer::Absolute" - event callback at a fixed future time
SYNOPSIS
use IO::Async::Timer::Absolute;
use POSIX qw( mktime );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my @time = gmtime;
my $timer = IO::Async::Timer::Absolute->new(
time => mktime( 0, 0, 0, $time[4]+1, $time[5], $time[6] ),
on_expire => sub {
print "It's midnight
";
$loop->stop;
},
);
$loop->add( $timer );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Timer implements one-shot events at a fixed time in the future. The object waits for a given timestamp, and
invokes its callback at that point in the future.
For a "Timer" object that waits for a delay relative to the time it is started, see instead IO::Async::Timer::Countdown.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_expire
Invoked when the timer expires.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_expire => CODE
CODE reference for the "on_expire" event.
time => NUM
The epoch time at which the timer will expire.
Once constructed, the timer object will need to be added to the "Loop" before it will work.
Unlike other timers, it does not make sense to "start" this object, because its expiry time is absolute, and not relative to the time it is
started.
