Ubuntu :: Pause A Task Via Command Line?
Apr 4, 2010
I have a task that I need to let run while I'm away from the computer. It's very CPU intensive and I've even had to throttle down my processor to 3GHz to keep it from overheating. I'm using a combination of GNOME Sensors App and CPU Frequency Scaling Monitor to control the overheating problem. I have the sensors app set to alarm and "killall" at 61 Degrees Celsius. The sensors app has an option where you can enter a command that it will run for you. All I need is to know what command to run that can pause this task. So later I can resume it.
I know it can be done. System Monitor has an option to "stop" a task. It also has "continue". This is how I've been doing it while I'm at the computer. So if anyone knows what the commands are that System Monitor uses, that would be a huge help. By the way, I'm using Ubuntu 9.10 with all current updates.
NOTE: For anyone who is about to flame me for having a computer that overheats and wants to tell me that this is the problem I should be after. It only overheats during this process. Not for any games or compiling or rendering or encoding. Nothing else. I have even bought a new heatsink and fan. I have redone the thermal compound on the Processor. My processor usually runs at idle around 36-39 Celcius and under normal load around 47-53 Celsius.

I need to copy all subdirectories and files from one directory to another ever 5 minutes or so, with the old data automatically being overwritten with the new data. I'd also like this to run at startup. Is there any way this can be done? If so, what program would I need to schedule the automation and what is the command line I would need.

what i need to do is to be able to place a command to slow down the sequence of commands in an Ubuntu script.
normally, the system will attempt to execute them all as fast as it can, but i need to be able to specify short pauses between commands
anyone know of a useful command to do this?
btw, the "sleep" command i saw somewhere hasn't quite worked in my scripts for some reason.

I need to run a script that I build to build a word list. Essentially what it does is run through a base list and expands that into billions of words. This way I can keep a small dictionary file and a script to expand it into a larger file (about 500 gigs). This script should take anywhere from 12-14 days to run and on my last day the power went out at my house. Is there anyway I can run this again with a fail over system? I know a battery back up is an ideal addition to my home server but if the power is out for an hour it wouldn't have made a difference. Also if I had the ability to pause the script do a reboot and resume it again that would be amazing.

How do I get a task bar for the commmand line for the tar.gz or tar.bz2 when compressing files? I want a task like wget has for download and like you get when you tar.gz or tar.bz2 with a gui.

The man page seems to indicate no. There is /etc/rc.d/init.d/halt on Fedora. It has a hard coded pause in it, but there's got to be a better way than to change that script.

Is there an equivalent command that will perform the same task as ALT+F4 keystroke? I want to create a simple script that lirc can use so I can set up a button on my remote to close program windows that pop up (like when plugging in usb thumb drives, inserting a dvd, and other windows), and avoid having to remote desktop or go into CLI to kill the window.

I guess there is some bash shell trick to run poweroff when an other command is over, like let's say su -c 'yum update'.
Creating a shell script with these two commands, the one below the other, would be sufficient? I can't try it now.

After upgrading from 10.10 to 11.04 all of a sudden, the task manager or task bar, keeps changing length. The individual window "buttons" themselves keep changing size - flashing even, and the space between them also changes. It is driving me nuts! The little system tray(?) icons no longer appear in the system tray, but all stacked on top of each other in the top left corner.

I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
My system:
Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

how to pass something 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
[code]....
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.

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?

I tried
Code:
chown -R owner:group *
which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?

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

I have my task list in evolution (mainly so it can sync with my phone and online task list) but I always forget to look at the task list. Is there an application or plugin which periodically displays the contents of the tasklist or even better, it briefly displays the most urgent/important tasks when I login? Or anything else which automatically displays the most important tasks. Currently I have to open the task list and look at them (which I usually forget). I do not mean some kind of alarm when the task is due but more a daily reminder of what to do.

How can we do everything, or as much as we can do, from the command line? In particular, I am trying to get rid of the top panel in Ubuntu. Because,
1) It takes unnecessary valuable space.
2) Even if I use a huge monitor, it introduces distraction to me while working.
I created a shortcut so that with a single keyboard key I can open a terminal. For example, if I want to restart the computer, I use: "sudo shutdown -r now". Or I can even create a shorter alias. So I do not need the logout menu. But my problem is, some programs put an icon on the top panel when they are working. So, what is the best way of using command line, and getting rid of the top menu.

I was wondring if 7zip still only runs in the command line. I searched and got a bunch of old threads like this: [URL].. but I'm not sure if that has changed since 2007. A GUI would be awesome.

sftp 10.99.99.99
ssh: connect to host 10.99.99.99 port 22: No route to host
Couldn't read packet: Connection reset by peer
