I centos version 5 installed on server 2, and I want to make a scheduled task that executes a shell script.This script should copy some files and directories from one server to another. I do not use DRBD and Heartbeat.
View 1 RepliesI would like to a build a CD image (of CentOS 5, x86_64 that loads into memory and boots to the OS without installing anything to hard drives. Then I would like the system to execute a shell script automatically. The shell script will have commands that will control execution.
The goal of this exercise is basically to pre-configure a system (RAID config, BIOS update, etc) automatically using the shell script before installing the OS. I would like the ability to change the shell script as needed and probably repackage the ISO image. I would prefer not to deal with building a source tree to accomplish this. this is something one could do using mkisofs.
i was reading on how to do scheduled tasks, however i couldnt find anything that was a scheduled task to copy a whole folder to a NAS(Network Storage) thats linked on my ubuntu desktop every 4 hours or so.
View 1 Replies View RelatedI have my background as a satellite picture of the earth. Right now I have a scheduled task to grab that picture off the internet (the website updates it every three hours) so my background is a 'live' snapshot of the earth.
I want to set up a scheduled task to take a screen shot every three hours, so that I can see, for example, the way the earth changes over the course of a day...a week, etc. I already have the Scheduled Task Manager from Gnome, but would anyone know what command I could use to do this?
My biggest problem is figuring out how to change the name of the picture it saves it as every time. (e.g. earth1.jpg, earth2.jpg, earth3.jpg, etc.)
I am trying to get Scheduled Task to run a bash script (which runs an rsync command) but it does not seem to be running. I can run the script from the command line with out a problem, but I have it scheduled in Scheduled Tasks to run once everyday and I can't find any evidence of it running or any indication why it does not run. is there a better GUI for scheduling tasks? I am running 10.04 server with xbuntu desktop
View 5 Replies View RelatedI am trying to write a script that connects to a server and executes some commands on there. Something like this:
#!/bin/sh
telnet remote_machine
cd /home/some_directory
cat a_file_in_current_directory
Unfortunately after login/password I guess the script doesn't jump past the telnet command, until I exit. What do I need to do to make the script start executing commands in the remote shell?
I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).
Here is the remainder of the KS :
lang en_US.UTF-8
keyboard us
timezone US/Eastern

I've figured out how to do much of this, but I haven't figured out how to do backups in Linux. I've been spoiled with Windows, with the built in backup system so simple to use. I find myself overwhelmed with the array of backup software, and unable to determine which to use. none of them seem to do everything I need them to do, but some come close, I think. I'm hoping someone here can help me out in figuring out which program to use and how to use it.
Here is what I need the backup software to do:
1. scheduled unattended backups, with alerts if the backups fail
2. a weekly full backup with incremental every 12 hours
3. removing the old backups when the new full backup runs, I would prefer to keep 2 weeks of backups, but that's not necessary
4. a GUI would be preferable, since my arthritic fingers don't always do as I want them to do. I typo things a lot, and the label worn off my backspace can attest to that.

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 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.

Specifically, I am trying to hunt down and kill a python 2.6 installation that just won't die.

I'm having trouble getting conky to boot friendly-like with the gwm. If I just set conky as a start up program, it floats above other windows, it seems to have loaded before the desktop actually did. So I googled it and found that many people use the conky shell scripts to make it sleep until the desktop load. I created one, made it executable, and restarted to see the effect and found that conky never launched at all (not visible, no running process).
Here is my startup shell script for conky:
Code:
#!/bin/bash
sleep 10 && conky;
This is how it should look if working properly. If I launch conky after login, it looks like this every time. [URL]. This is how it looks if I simply set it to open upon startup with no script. [URL]. If I try to open it with the script, I simply never see anything in conkys place. It seems like the script never executes. I've tried setting longer and shorter sleep times, but I never see so much as a single instance of conky running.
I completely switched to Ubuntu 6 months ago. I kept my secondary sata hd as ntfs for a while but started having permission problems. I switched it to ext4 and that worked for a while but then it started having permission problems again. Specifically, I can't execute anything on that hd drive. I converted it to ext2 and it still didn't help. I have 2 executable modules that I moved up to the root directory to make this simple and they look like this:
tom@tom-desktop:/media/sda1$ ls -l
total 3088
-rwxr-xr-x 1 tom tom 3099451 2011-04-23 16:36 bochs

I have a hard to reproduce (seen a couple times in a month) issue where my program seems like it is hung (not increasing in cputime), however, it is in the runnable state and never gets to run. The cpus are 99% idle according to vmstat and the load is 5 (which is equal to the number of threads in my program that are in the R state) according to ps, and there are no processes on the system in the 'D' state. The other major oddity is that one of the migration threads has a cputime usage almost equal to the uptime of the system. Typically migration threads have a cputime on the order of seconds across hundreds of days of uptime, but in this case the migration thread has DAYS of cputime according to ps.
The last time this happened, I went around saving as much /proc/X information that I could into logs for referring to later, before I had to reboot the box to get it running back to normal. (because in this state, a kill -9 is not heeded by my program)Does anyone have any idea what could cause this? I am not sure if this is a scheduling bug or a bug in my program (the likelier case).I have a wealth of logs to look through if anyone can suggest something specific to look for.
I want to use a desktop icon shortcut that essentially does this...
Is there a way I can do this? I don't really want to create an alias because I just want it to be an icon I double click to do all of this. But if I have to create an alias in which it does these ocmmands then I use the shortcut to terminal... then it types the alias that is fine also.
even though this is a simple task I always have problems to do this.I want to execute the following#!/bin/bashjava -jar JabRef-2.6.jaror in other words this is the command I use in konsole to make the application to launch.Then usully I try to create a desktop in the icon either by using a. create link to locationorb. create link to application.where I select as file the file myfile.sh that contains the two lines of code I posted above (see again below)
"#!/bin/bashjava -jar JabRef-2.6.jar"I do this file executable by using the chmod +x.Sometimes I think this works while others like now I only receive the cursor bouncing for sometime before it dissapears

Iv got an assignment to complete and I'm stuck at the basic level.
A part of the assigned problem is :
The main process will read the file, and will create N number of child processes (Where N is taken as input) as early as possible before all the children starts its execution. Before creation of each child, the main process should read the file to store all the required data in then corresponding data structure. Child processes should not read the file for getting their information.
As far as my knowledge about this , the child executes before the parent. How do I make the parent not pass the control to it's children before it finishes creating all the children?

I would like to make a script, where I specify my Cisco devices IP addresses as arguments to the script and then this script automatically logs into every one of them and does "show version" and "exit" in every Cisco device. I have public/private key authentication system with my Cisco devices- thats why I'm using ssh-agent and ssh-add. I did something like this:
Code:
#!/bin/bash
if [ -z $1 ]; then
echo USAGE:
echo "$0 IP1 IP2 IP3 IPn"
[code].......
However, it logs nicely into the first device(I'm able to execute IOS commands in this first Cisco device etc) and then does nothing further.
I have a computer with a trackpad and a touchscreen. I want to run unclutter if I use the touchscreen, and kill it when I use the trackpad or a USB mouse.

In Ubuntu 10.10 I want to have a shell script execute on bootup after everything else is done, *just* before the computer gets to and sits at the login screen. I find this easy in CentOS/Red Hat. If I place my scripts in /etc/inittab near the end, right after the mingettys, that is PERFECT. But Ubuntu has no /etc/inittab and I have spent the past few days going over and over and OVER more info about Upstart and the rcX scripts and I can't seem to get it. Anything I place in an rcX script runs too late, only after the machine is past the login screen i.e. a human must log in first. And I would rather not have to enable auto-login. I've heard that Ubuntu will honor an /etc/inittab file if you create one, and it does, but that too runs too late, only after a human has logged in. Can anyone tell me where a script should be placed in Ubuntu to execute after all system initialization is done, but before human interaction is required?
View 3 Replies View RelatedI use Kaffeine to record live TV to disk for later playback. I've been putting up with Kaffeine's little foibles for the last little while, but tonight (for the second night in a row) I accidentally closed it and consequently it didn't record anything.
Is there any software I can use to construct a recording schedule which will then not be dependent on me remembering to leave a particular app running? I don't really need this in MPEG4 or anything. The PC stays on 24x7 - I just need it to launch a recording at the correct time.
I've avoided MythTV in all it's incarnations because I want the computer to still function as a normal PC most of the time, and from my admittedly brief trial of MythTV it took over the PC and wouldn't let me open a web browser or a mail client.
