Installation error with "Proview open source process control"
location: linuxquestions.com - date: August 9, 2011
I am using ubuntu 10.10. I downloaded "pwr47_4.7.0-2ubuntu_i386.deb" from proview.se. While installing this error appeared on window
"Dependency is not satisfiable: libmysqlclient15off (>= 5.1.30really5.0.83-0ubuntu3)"
My system uses pendium 4 processor. Can someone tell me what is the issue that i am not able to install and how to solve this problem.

Process / Job control.
location: linuxquestions.com - date: January 5, 2010
I have a script which runs: -
e2fsck -p -v -c -f /dev/sdb1 > e2fsck_sdb.log &
However, although this runs successfully in the background, I'd like to be able to log off and return later, pull it to the foreground and see how it's doing. When running this, I don't get a job number - it simply returns to the prompt - and using "jobs" returns nothing, although I can see it running by using "ps". I assume this has somehow got divorced from the shell session, so I am unable to use "fg" to bring it back to foreground.
Since I can get the Process ID very easily, is there a way to pull a process to the foreground from it's PID rather than it's job number? Or can I somehow get the correct job number from the PID in order to use "fg"?
Thanks for any help!
how to identify a zombie process and control it after parent dies
- date: January 21, 2008
I have created a zombie process using fork,
and i am viewing the processes using
vijay]$ ps -al
F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD
0 S 500 2893 2752 0 80 0 - 11193 - pts/4 00:00:09 gedit
1 R 500 4852 1 60 80 0 - 414 - pts/4 00:02:37 a.out
0 R 500 4914 4853 1 80 0 - 1134 - pts/1 00:00:00 ps[/SIZE][/SIZE]
The PPID which is having the value 1 is the zombie process,
Can we say any PPID having 1 is a zombie process or does it represent Zombie with any symbol or any other identification?
Can we have any command over zombie process other than killing it?
Is it possible to put foreground process into background without suspending (control +z)?
location: linuxexchange.com - date: May 15, 2013
I am running an application which receives TCP and UDP packets and therefore cannot be suspended. I intially ran 3 processes of the same application, with different arguments, in background mode using &. When I did only $fg, all three process came into foreground. Now I want to send them to background again but without suspension. How can I do that?
How to control which core a process runs on?
location: linuxexchange.com - date: September 15, 2012
I can understand how one can write a program that uses multiple processes or threads: fork() a new process and use IPC, or create multiple threads and use those sorts of communication mechanisms.
I also understand context switching. That is, with only once CPU, the operating system schedules time for each process (and there are tons of scheduling algorithms out there) and thereby we achieve running multiple processes simultaneously.
And now that we have multi-core processors (or multi-processor computers), we could have two processes running simultaneously on two separate cores.
My question is about the last scenario: how does the kernel control which core a process runs on? Which system calls (in Linux, or even Windows) schedule a process on a specific core?
The reason I'm asking: I'm working on a project for school where we are to explore a recent topic in computing - and I chose multi-core architectures. There seems to be a lot of material on how to program in that kind of envir
[SOLVED] How to control process to not consume more then 20% of CPU?
location: ubuntuforums.com - date: November 19, 2008
using Ubuntu 8.10 I have installed VirtualBox to have multiple virtual machines. In VirtualBox tool I can set max memory consumption, but can't set max CPU consumption. I have 5 virtual computers on my physical computer and I would like to set that each virtual computer should not take more then 20% of CPU power.
Is there any way on Linux that I could control the maximum CPU consumption by each Linux process?
what's the best practice to control linux process from web page( Rails)?

currently I am facing to a problem that: we need to control the linux scripts running in background from web page. e.g. we could start/stop a 'script' via the button on the webpage.
also another good example is:

Sending Control C to a process in java.
location: ubuntuforums.com - date: November 28, 2008
I'm writing a java app that uses arecord and allows the user to terminate it when they need to. The problem is that I don't know how to send the Control-C signal to it. I started it like this:
String com1 = "/bin/bash -c arecord -f cd -t raw | lame -x - ";
String com2 = date;
String com3 = ".mp3";
String fullCom = com1 + com2 + com3;
Process record = Runtime.getRuntime().exec(fullCom);
// then stop the recording
System.out.println("Recording. Enter any key to stop recording.");
// etc, etc
It runs well, but I can't find a way to stop it cleanly so that it actually saves the file... when I use record.destroy() or exit(0), the file is not saved. Does anyone know how to send the Control-C signal to this process?
Thanks a lot!
