That specification is very difficult to interpret. Some comments to improve:
- post the full error messages or strange behaviour in lieu of "did not work"
- post sample files (in code tags) instead of pictures so people can work on them
- explain what uncommon programs (sel? del?) do; give success and failure output
I don't know a thing about "direct" nor "sel proc". If the output of the latter is close to what you posted as an image, this might be a starting point for you to taylor and improve:
0 is a PID that will never occur so it seemed quite safe to use as the "token" to convey success.. Killing processes by script is a delicate thing so you should know exactly what you are doing, and you might want to build in other safety steps.
I meant old not hold :)
I need to kill a process if it's over an hour old and then send an e-mail of the list that was killed.....?
I need to kill ps -ef | grep stashd | grep ' older than an hour?'

Hello Everyone,
I have a process that should be always running. Unfortunately, this process is getting down almost every 10 minutes. I want to make a script that verify the state of this process: If the process is up, the script shouldn't do nothing and if it's down he should run it.

Hi Experts,
I am facing one problem here which is one process always stuck in running state which causes the other similar process to sleep state . This causes my system in hanged state.

net::http::nb
Net::HTTP::NB(3pm) User Contributed Perl Documentation Net::HTTP::NB(3pm)NAME
Net::HTTP::NB - Non-blocking HTTP client
SYNOPSIS
use Net::HTTP::NB;
my $s = Net::HTTP::NB->new(Host => "www.perl.com") || die $@;
$s->write_request(GET => "/");
use IO::Select;
my $sel = IO::Select->new($s);
READ_HEADER: {
die "Header timeout" unless $sel->can_read(10);
my($code, $mess, %h) = $s->read_response_headers;
redo READ_HEADER unless $code;
}
while(1) {
die "Body timeout" unless $sel->can_read(10);
my $buf;
my $n = $s->read_entity_body($buf, 1024);
last unless $n;
print $buf;
}
DESCRIPTION
Same interface as "Net::HTTP" but it will never try multiple reads when the read_response_headers() or read_entity_body() methods are
invoked. This make it possible to multiplex multiple Net::HTTP::NB using select without risk blocking.
If read_response_headers() did not see enough data to complete the headers an empty list is returned.
If read_entity_body() did not see new entity data in its read the value -1 is returned.
