We've a process on AIX UNIX server which is executed by multiple uses during a day. I wish to create a log file for every time the process is executed. I wish to know how unique are PID(s) on AIX UNIX servers if I were to name the log files with <date> and <PID>?
E.g. If I create my output files having the details such as
With my limited understanding of UNIX and from what I've read on the forum https://www.unix.com/unix-advanced-expert-users/2896-obtaining-process-id-pid.html AIX system sequentially assigns a limited set of PIDs and re-utilizes them as and when processes get freed and slot is available for allocation by dispatcher.
Please suggest a suitable way to uniquely identify the process execution during the day. I am also considering adding datetime hh:mm:ss to the log name to uniquely identify the same E.g. change log file name to

$!>PID_FILES
I try to get the PID of the last process on the files called PID_FILES.
But the command stands by on the output screen. I have to tape on ENTER to get the prompt and continue .
How may I simulate this action ( tape on ENTER ).

1. If I use an software application(which connects to the database in the server) in my local pc, how many PID should be registered? Would there be PID for the session and another PID for socket connection?

Hi!
I'm facing a unique problem!
When I run a program on HPUX, it runs fine but it also produces a bunch of files of the format:
tr.<pid>.number
the contents of these files are a bunch of numbers and I know for a fact that these files are not created by the program I'm running.

Hi All,
I am getting the PID of a process using its name using the following command
in a script
mypid=`ps aux | awk '/test5/ && !/awk/ { print $2 }'`
echo PID is $mypid
The problem is the PID is not getting printed. But when i run the command directly in shell, the PID got printed.

Hi to everybody.
Is it possible to nohup a process and redirect the output to a file containing the PID?
E.g. if
nohup filename > out.nohup
associate the PID=8074 to filename, is it possible to call the output file something like out_8074.nohup instead of out.nohup? By this way it would... (0 Replies)

Hi all,
I am generating the coredump of my JBoss, and by default it puts it in to a particular directory. i.e. JBOSS_HOME/. I would like this output file to be created, lets say in /tmp/dump/.
I tried the following:

Hi Friends
I have 2 solaris boxes and I need to check certain directories (on local filesystem and mounted nfs) to make sure that they match up on both boxes and to delete or move the other mismatches to elsewhere on the local filesystem.

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
