Hi,
Am working on linux. while forking in a loop how to avoid the child process from forking..for example
int n = 5;
pid_t pid;
pid_t ch_pid;
/*exactly wanted to create n processes and not 2^n processes*/
for(i = 0; i < n;i++)
{
if(pid = fork())

Hello guys,
what i want to do is to print a table with two columns (user :: #procs) on the stdout.
The first column should show the users and the second one the number of processes the respective user runs.

I need a mechanism to fork child processes and all child processes should connect to a server.but the number of child processes should be limited(for ex:50)
Here's my pseudo, but I cant figure out how to limit the child process number. Should I use a semaphore? or what?

Hi
Is there a way to count how many processes a script has started, count how many of these have finished, and make the script wait if their difference goes over a given threshold?

Hi guys,
I am struggling with adapting my script to increase the performance.
I created a ksh script to process a lot of files in parallel.
I would like to know how can I do in such a way that a constant number of processes is always up (until all is finished).
What I have is (not actual... (8 Replies)
Hello all,
This is my requirement:
1. I have 6 VMs running Apache (for Oracle EBS) as Linux user oracle.
2. From a central server (VM), I need to login to all the 6 VMs as oracle user (I have already set up ssh equivalence, so it is password less authentication).
3. Find the number of... (4 Replies)
Is there a certain man command I'm missing here? I searched in ps but I couldn't find something that would give me the number of processes running on root.
I only want to see the number of processes, not the processes itself. (2 Replies)
I am trying to implement the below using Ksh script on a Lx machine.
There is a file(input_file) with 100K records. For each of these records, certain script(process_rec) needs to be called with the record as input. Sequential processing is time-consuming and parallel processing would eat up... (2 Replies)
Hi there,
I am having a problem on an AIX server running a WebSphere MQ instance. The problem is that sometimes it seems to reach process limit, but I do not find the processes themselves.

kill
KILL(1) Linux Programmer's Manual KILL(1)NAME
kill - terminate a process
SYNOPSIS
kill [ -s signal | -p ] [ -a ] [ -- ] pid ...
kill -l [ signal ]
DESCRIPTION
The command kill sends the specified signal to the specified process or process group. If no signal is specified, the TERM signal is sent.
The TERM signal will kill processes which do not catch this signal. For other processes, it may be necessary to use the KILL (9) signal,
since this signal cannot be caught.
Most modern shells have a builtin kill function, with a usage rather similar to that of the command described here. The `-a' and `-p'
options, and the possibility to specify pids by command name is a local extension.
OPTIONS
pid... Specify the list of processes that kill should signal. Each pid can be one of five things:
n where n is larger than 0. The process with pid n will be signaled.
0 All processes in the current process group are signaled.
-1 All processes with pid larger than 1 will be signaled.
-n where n is larger than 1. All processes in process group n are signaled. When an argument of the form `-n' is given, and it
is meant to denote a process group, either the signal must be specified first, or the argument must be preceded by a `--'
option, otherwise it will be taken as the signal to send.
commandname
All processes invoked using that name will be signaled.
-s signal
Specify the signal to send. The signal may be given as a signal name or number.
-l Print a list of signal names. These are found in /usr/include/linux/signal.h
-a Do not restrict the commandname-to-pid conversion to processes with the same uid as the present process.
-p Specify that kill should only print the process id (pid) of the named processes, and not send any signals.

Taken from BSD 4.4. The ability to translate process names to process ids was added by Salvatore Valente <svalente@mit.edu>.
