I have many processes running that printf local debug. (they will log to file later!) I start them by
Code:
( sleep 20000000 | fp ) & else they get killed/stop by themselves. So now its running in the background, I want to bring it to the front to see the printfs.

I know a program running in the background can be brought to the foreground by typing 'fg'. So, if
command_line &
really runs the program in the background, my question has just been answered. But then all reduces to this question (yeah, I know; but I'm asking in earnest): does the ampersand sign make the program run in the background?
I got curious during the construction of my program to search for blocks of text that contain certain words, and wanted to print out blocks of text with the words I was searching for, initially, in ALL CAPS and seperated by tabs for easy identification. That got boring, though, so I thought, "Can printf do colors, too?" Yes it can.... Who knew?

Sometimes when I have two or more windows open, the window in the foreground will be white, or blank. This most notably happens when I have Firefox and LibreOffice open in the same desktop. The window in the background is clearly visible, and when I right click on the window in the foreground, a normal context menu comes up. This also sometimes happens when there is only one window on a desktop.
I have played on and off with ubuntu over the years, and am currently using 11.04 on an older HP with an Athlon 64 chip. You may consider my background knowledge of the system to be one step above nil. I'm happy to provide any system info you may want, but you'll likely have to tell me how to obtain it.
Is it possible to schedule a process in the foreground? Lets say a cron schedule to be ran at 9:00. I would like to come back at 9:30, see how the process is running, and being able to interact with it... lets say kill it, or whatever. Is it possible? (Its not necessary to use cron, but it must be in Command Line)

View 4 Replies View RelatedI am running some Matlab simulations on Natty Narwhal. Each time this matlab script outputs a figure, Matlab jumps to the foreground, as if I clicked it on the launcher. This is really annoying, because if I'm typing something in my browser for example, and a figure is displayed, I am taken away from my browser and I have to click the browser to resume typing.Is there a way to just have Matlab run in the background without interfering my other work?

I had started a process through ssh and then i did 'cntrl+Z' and 'bg' and 'disown' before closing the ssh connection.

Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
Whenever I'm playing a video and bring another application to the foreground, the video window appears over the foreground application:
I'm running Natty Narwhal 64-bit. This didn't happen back in Maverick. The hardware is an Asus K42JR laptop. If there's any more detailed information that I can provide to help narrow this problem down, please let me know.
I've found a similar issue on the forums, but it seems a bit different. This guy also has foreground window problems, but in his case they occur with non-video applications and are not consistent (it only happens 10% of the time).
With me, it always occurs with only video playback. The choice of video application for playback does not appear to matter (I've tried Totem, VLC). Strangely, the problem doesn't occur when viewing flash videos from within Chrome.
I've read about this. Everyone says to use ~/.Xresources or ~/.Xdefaults, and it doesn't work for me. It doesn't do anything at all, in fact. I'm trying to use this:
Code:
XTerm*background: black
XTerm*foreground: white
In the ~/.X* files, it won't work. I read that another way of doing it is using
Code:
xrdb -merge .x_settings_file
This will work for me. It's the only thing I can get to work. But when I restart, it will have to be done again. I'm using Slackware 12.2.
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.

If you don't know, users are able to quickly resize windows using the "ALT+MiddleClick" key shortcut/combo. Basically, hold the ALT key, and mouse middle click and hold on a window. Move the mouse around, and it will resize the window for you.
STEPS TO REPRODUCE:
1) Open a single Window.
2) Near the bottom-right-hand corner of the window, ALT+MiddleClick and drag. It should resize. Great. It works.
What Doesn't Work:
Now, the problem arises when you have multiple windows open on the desktop, they are "layered". i.e. you might have several windows open "behind" the one currently "up front". Example:
If I try to ALT+MiddleClick the "foreground window", it rarely actually resizes THAT window, and instead jumps one of the windows from behind to the front, and resizes that one instead!
STEPS TO REPRODUCE:
1) Open 3x gnome-terminal windows and say some nautilus window. Place them overtop one another. (like the above image)
2) Try to ALT+MiddleClick the foreground window.
3) Repeat this always trying to grab the foreground window.
For me, the window manager seems to bring some window from the background to the front! Desktop Recording of the Problem: [URL]
Running:
* Ubuntu 10.10
* compiz window manager (the problem does not occur with metacity)

After upgrading to 11.04, I noticed something strange, being that when I want to drag a file or folder from one Nautilus folder window to another which is not visible, I can no longer hold the item over said folder's taskbar button and wait for it to appear. It just shows the + for copy, and when I let go (which I have no choice but to eventually do), it creates a launcher to that item (I assume it's doing that, and not actually copying there, but the + has me unsure).
I've looked in Nautilus's preferences to see if this is some new behaviour that I can revert back to, but could find nothing there.
I'm of course using the Classic desktop with bottom panel being the taskbar. If you know how I can rectify this, please let me know, as the times I would want to create a file or folder launcher without the usual hassle would be rare, but I am constantly dragging stuff from one folder to another, and it would be a real pain to have to line up source and destination folders each time.
Is there a command which can be used to run some other command on a few lines from a file or an o/p of some file. (the kind of role that -exec option does for the find command). (I have solved the purpose using a bash loop but would like to know if there exists a command).
