Fedora :: Open Multi Processes (command) Using Only One Terminal?
Apr 28, 2010
I just switch to fedora from windows recently. And I love the terminal of fedora alot. The problem is when I run some command on the terminal, I need to wait for that command to finish before executing another command. This is very inconvinient, say If I open eclipse using the terminal, this eclipse program will hog to the terminal until I closed it. So if I want to use terminal again I have to open another one.Hence the question is: Is there any way open multi processes(command) using only one terminal?

When I open a terminal and start the 'top' command to view the running processes, in the summary view I get 4 users. I guess that in addition to my account the root runs in the background but who are the other 2??

Few days ago, the server did not respond to a ssh request from a user at night. A user tried to check what went wrong with computer and tried to login from terminal next morning. As the computer was unresponsive, he somehow decided to boot it by turning the power off. To make the story short, the server rebooted; however, he can't login to his account. Actually, the server could not start some processes; but was able to ask user to enter his account username. Even though, he enters the correct username and password, server does not accept the request. I also could not login as root.
I just checked the server logs by booting it in single user mode. Here are some interesting lines:
Before the reboot:
irqbalance : can't balance irqs on a uniprocessor system: failed
After the reboot:
irqbalance : can't balance irqs on a uniprocessor system: failed
fsck:
This might be something related with shadow file.
Here is part of /etc/shadow

I'm a day-1 Ubuntu user with a question about getting multi-touch scrolling enabled on my laptop automatically each time 10.04 loads. I'm very green when it comes to all-things-Linux. Basically, I'm just searching for help, following step-by-step guides, and copying-and-pasting commands. I found the following website that helped me create a little script to enable multi-touch control:[URL]...
But I can't figure out the last step: "All you need to do to have this run at startup [instead of typing ./2fsrl in terminal manually each time] is add it to you startup programs." I tried creating a file path to the 2fsrl file in Preferences -> Startup Applications program, but upon re-starting the laptop, the multi-touch isn't enabled anymore. I'm sure I'm missing something simple. Can anyone advise? (Keep in mind my beginner's status!)

I have a problem that I can't seem to figure out. I can easily create a .sh file that will execute a command in Terminal, but as soon as it executes the terminal disappears. How do I get it to stay? My idea is to have the keyboard shortcut "ctrl+alt+del" open a .sh file with the contents "ps ax". Then it would be just like having a task manager; the terminal would open with "ps ax" already executed, and all I would have to do is kill the process number.

The following code is for monitoring the memory used by apache processes. But I got a problem that the data I got by this script is much larger than the physical memory. It was said that there are some libraries used simultaneously by many processes, so the data I got has some double counted part. Because apache has many httpd processes.
Anyone have an idea of getting the multi-processes memory used?
Code:
#!/bin/sh
#G.sh 20100813
USAGE="Usage: $0 processName"

I am a bit confused with MPM. I read one the article here: [URL]. Still have few very basic doubts:
1. What exactly is a MPM, a module has a specific function to do whats the specific function of MPM?
2. What are the "multi processes" it handles? Is it connections?
Quoting from the articles:
"The main difference between MPMs and normal modules is that only one of the former can be used and multiple ones can be loaded in the latter".
3. There are multiple MPM but aren't they operate differently and may cause conflict when more than one is loaded and operating?
I am really looking for concept of MPM

In Xubuntu 9.04 I could right click in any directory folder and have the option of opening a terminal window "there". So the terminal command line would open preloaded to that directory. I know, I'm lazy, but it sure made life (and command line work) easier. But it's not available in my new install of Ubuntu 10.04. Now, I know that my gui environment has changed from xfce to gnome, but I would have expected MORE features, not less.

Using Ubuntu server 10.04.2 64-bit all up to date.
I am running multi-threaded processes. These use OpenMP in my own code and the multi-threaded ACML maths library. When run in the foreground, everything is fine i.e. if I have set
export OMP_NUM_THREADS=8
then when I start all 8 cores are in use and things whizz along. However, when running overnight and logged out using e.g. 'at now + 1 minute' then the command, I am only getting about 130% CPU and it slows down accordingly. I have tried renice'ing and calling from within a bash script in case sh is doing something odd but nothing seems to solve it. I am sure that in the recent past this wasn't the case.
The libraries being used are shared versions in case that might have any bearing.

I have written a simple script which has to find required patterns from a bunch of files ( where each file is around 2 GB each,which contain the output of seq 1 10000000000000) on an 8 core machine.I am current forking 6 child processes which run simultaneously on 6 cores of the processor & have to search for the required pattern in 6 different files & inform the parent process when a pattern is found using a PIPE.
The problem is,when a child process is done reading a text file looking for a pattern,it is becoming a zombie process.It exits cleanly when i put a $SIG{CHLD} = "IGNORE"; in the script.Can any one tell me whats going on & how do i improve the communication between child and parent processes?
Code:
#!/bin/perl
use strict;

I am trying to use a command to open a partition or disc from the top like open up external drive, and not have to be externaldrive/videos or whatever. The reason being is to use in cairo dock, I have tried to drag n drop like i am able to with regular folders, but no good. I seen the option to run a command, and figured I would try it that way.
I have the partitions and discs i want to access mounted. they are:
External Drive (/dev/sdc1)
Storage (/dev/sdb1)
Windows (/dev/sda2)
I tried to open them in terminal, /media/storage: no such file or directory;
/dev/sdc1: Permission denied;
open /media/storage or /dev/sdc1
Couldn't get a file descriptor referring to the console;
se7en@PC:~$ nautilus /media/storage or nautilus /dev/sdc1 .....
Along with a pop-up saying 'the location is not a folder'.

I have the following rsync command for making some backups:
Code:
rsync -r --progress --delete -H --numeric-ids -a --exclude=.gvfs /source /media/Backup
If I paste that in my Terminal, it will perform a backup of all the files and show me what's going on in the Terminal window. But how can I make that into a launcher? I have made a launcher on my desktop with that code in its Properties, but double-clicking it starts the rsync process (I can see HDD activity) but a Terminal window won't open.

I wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs

I'm having Ubuntu Kramic Koala and i want to create a custom application launcher on the panel so when it is clicked it should open a terminal window and run the following command and then show the output for 5 secs and then closes the terminal... how can i do this?
Code:
cat /proc/sys/vm/laptop_mode && sleep 5
the above command is what i want to be executed at time of running the custom application launcher. if i paste the command in a terminal, it will show the output for 5 secs and then terminates... that's almost what i want. what i exactly want is that, i want it to work like when i click on the shortcut launcher, it should open a terminal and then exectues that command, show the output for 5 sec, pause, and then exits the teriminal.

Every time I boot up ubuntu I usually open 3 terminal windows and ssh into the same server. I would like to either click a shortcut, or run a single terminal command that will do the equivalent.
I came across the "gnome-terminal" command, but I was unable to get it to trigger an ssh command.
Ideally I would like to have a script that I pass in the number of windows I want to open and the server I would like to ssh into for each window.
