How do you find the parent process of zombie processes?
When the child process is something where the parent is not entirely obvious...
Is there some way to list processes in tree format or something?

I want to capture PID of a program and kill it using the PID if the program is been executing beyond 5 seconds.The problem I'm facing is I have another copy of the same program running under different shell script, and the above code is killing both the process. How do I specifically kill the program which has started under the current running shell script.

Sometimes (rarely) when I try to open VLC it wont open, but it stays in the background and takes 98-100% of one core.
The problem is that I can't kill that vlc-process.
Code: Select allkillall vlc
will NOT kill it
and
Code: Select allkill 31641
won't work either
top shows
Code: Select allPID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
31641 xxxxxxxx 20 0 1320248 64384 39120 S 100.0 1.6 44:51.94 vlc
Is there any way to kill the vlc-process (without booting the machine)? I also tried the "killall vlc" and "kill 31641" as root with the same results.
I have Debian jessie and the only "nonofficial" repositories I have enabled are
#google chrome
http://dl.google.com/linux/chrome/deb stable main
#Backports
deb http://httpredir.debian.org/debian jessie-backports main
And from those I have installed only chrome, and wine-development, and I dont think those could have anything to do with this problem.
Booting the machine does work, but I don't want to boot my machine just now. This happens about once per week

I'm writting a program that uses a USB webcam. Sometimes the program crashes and exits, but sometimes it crashes and becomes a zombie process, which I can't kill even with -9/-KILL signal. When that happens, all access to th USB webcam is totally interrupted and all attempts to communicate with it fail.I'm looking for a way to either force this process to terminate or to at least make it release the webcam so I can use it again. So far, the only way I've found to regain control of the camera is to reboot

Slack is 32bit. Frequently, firefox becomes unresponsive. I can close the window, but the process is not terminated. I am not able to restart firefox without rebooting.
When this problems occurs the firefox processes are not terminated by the 'kill' command. Example
Code:
tim@bart:/home/http/run/baker/cron$ ps aux | grep firefox
tim 3780 0.0 0.0 3356 1640 ? S 15:59 0:00 /bin/sh /usr/bin/firefox
tim 3792 0.0 0.0 3404 1696 ? S 15:59 0:00 /bin/sh /usr/lib/firefox-3.5.2/run-mozilla.sh /usr/lib/firefox-3.5.2/firefox-bin
tim 3796 0.3 3.2 316560 95712 ? Sl 15:59 0:21 /usr/lib/firefox-3.5.2/firefox-bin
[Code]....

In the comments section of this blog, the commenter "Pratik" claims that you can edit a running bash script, without killing it, and have the changes picked up by the running script. He claims you can do this by editing files in /proc. Now, I know how to find the /proc folder that contains the data on the running process, Code: cd /proc/`pgrep process_name` But I can't figure out what I should do if I want to edit a running bash script.

I am trying to kill child process without killing the parent and seem to be having issues doing so. I have tried quite a few different commands and the end result is either killing all of them including the parent or not killing them at all.

I haveing a big problem atm (just after to upgrade to 10.04). I have a simply and easy script that sent a halt command to every KVM virtual machine actually running into the server. this script is/and was) palced as a init-rc script in rc0/rc1 and rc6 lvls. Just after to upgrade, I have noticed that this script is executed but the system ignore the time that it require to finish (giving time to correctly stop a single virtual machine). Aftert 5 second it start sending SIG-TERM and SIGN-KILL to any currect process and then reboot/halt.
I have just done a new script using upstart and I got just the same result. What is happending? why is the waiting the init secuence for a valid/or_not termination of any init script. I am so sorry for this crap english I have never study this language so I try to do my best anytime I speak it (or try ti..).

I have some heavy, long processes running on remote Linux machines. I use my laptop to SSH to these machine and run the processes from my couch.
BUT, when I want to shutdown my laptop, I am in trouble since the remote processes are killed.
I did my research and found out that "screen" is a great solution for me, it is! (As long as I don't SHUTDOWN my laptop). Isn't there a way to "persist" the "screen" sessions so I can shut it down and then re-attach to a session?

I install the antivirus, ClamAV, onto a RedHat 4.8 box (yes it has to be that release of the OS to work with my other software needs) and after the install and giving the permissions to another user/group dedicated to this AV I get a ton of errors. After the install a few things pop up after a restart/logout. When trying to log back in the Gnome environment crashes so you cannot access any acct aside from using the text based environment. Two other error windows appear as well, one mentioning Bonobo has died and the other saying that Nautilus cannot be started due to Bonobo. I'm not too familiar with Bonobo can anyone fill me in on why those errors occured?

user@host$ killall -9 -u user Will it definitely kill all processes owned by user (including forkbombs)?
No new processes is spawned to user from other users. No user's processes are in D-sleep and unkillable.No processes are trying to detect and ptrace or terminate this started killall (but they can ptrace or do other things with each other) There is ulimit that prevents too much processes (but killall is already started and allocated it's memory)
E.g. if killall will finish untampered and successfully is it 100% that no processes are left with this uid? If no, how to do it properly (with standard commands and no root access). Will SysRq+I definitely kill all things (even replicating)?

Possible Duplicate: Leave bash script running on remote terminal while not logged in? I run a program, say ./a.out 10 from the shell prompt. Assume that there's a while(1) inside the program being run. Now if I try to close the shell, it warns me that it'll kill my running program too! So, how to kill the shell and still let my program continue running in the background?
I tried exec ./a.out 10 but the shell is still there. Another alternative is to simply double click my executable but then how will I pass command line parameters?

Code:
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
[code]....
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
