Ubuntu :: How To Tell Which Binary Actually Executes

Apr 20, 2010

Is there a command that can tell me which binary actually executes for some program name? "whereis" seems to do something different.

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

whereis just seems to be returning anything with "python" in its name, but I want to know which binary thinks it is python 2.6.5. (By the way, I've tried all the above manually, and it isn't any of them)

Ubuntu :: Conky Startup Script Never Executes

May 6, 2010

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.

Ubuntu :: Secondary Hd Permission Denied On All Executes?

Jun 7, 2011

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
-rwxr-xr-x 1 tom tom 26064 2010-09-11 08:48 bzip2

Ubuntu :: Daemon That Executes Commands Based On Input Device In Use?

Jan 28, 2011

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.

The I'm pretty sure the touchscreen is /dev/input/mouse0, and the trackpad is /dev/input/mouse1

I have a general idea of how this should work, but no idea what tools and commands to use to implement it.

Ubuntu :: Part Of Boot Process Executes Just Before Login Screen?

Apr 12, 2011

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?

General :: RT Process Stuck As Runnable 'R' / But Never Executes

Jul 28, 2011

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.

General :: How To Create Multiple Children Before Any Child Executes

Aug 27, 2010

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?

Programming :: Script Which Logs Into Devices Over Ssh And Executes Commands?

Mar 23, 2010

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.

CentOS 5 :: Creating A Simple Live CD That Executes A Shell Script?

Mar 9, 2010

I 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.

General :: Bash Scripting - Executes A Few Perl Scripts - Create A New Array And Take The Hostname

Apr 4, 2011

I'm writing a bash script that executes a few perl scripts. One of the perl scripts that I need to execute requires two arguments with it. The arguments are stored in a txt file, each line contains a hostname and its corresponding IP address separated by a ":" (colon), the txt file looks like this below:

[Code]...

I'm not sure if it's the best way to accomplish this but here it goes. In the bash file, let's call it getHosts.sh, I create an array and assign each line of the file to an element in that array. I then think I need to create a new array where I take the hostname (which is before the ":") separate it from its IP address and place the IP address on a new line just below the hostname (this way I can reference to it like $hostNames[$x] would be the hostname, and $hostNames[$x+1] would be its IP address). So the new array would now look like this below:

Programming :: Create A RS232 C Program That Executes A Series Of Commands Down The Line To A Robot?

Here is my code:

#include <sys/signal.h>

Ubuntu :: Make A Startup Script That Executes A Simple Php Script At Boot?

Mar 24, 2011

trying to make a startup script that executes a simple php script at boot. The stipulation is that it must be run after fstab is processed because it requires access to a volume that fstab mounts. As it is, it doesn't seem to be running properly at startup, and I suspect that it is simply running before the volume is mounted. The script does not need root access. If I run it once I login, it works fine.

Also, is there a way to determine the output of a startup script?I am have configured a bash script called module.sh that cd's to the scripts directory (in the external volume) and then executes the script. I didn't forget the ampersand after the php invocation. I used update-rc.d module.sh defaults to configure it.

CentOS 5 :: Create A CentOS Based LiveCD That Mounts A NFS Share And Executes One Script?

Aug 14, 2009

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

Ubuntu :: Can't Run This Binary / Wh Is So?

Apr 29, 2010

I'm going through a tutorial here to help me know how to wander around my system in the terminal and just understand better on a general level.

I'm trying to simply figure out how to compile and run some software from source. I get to my directory where the then installed binary sits. I understand I'm supposed to enter in the command:

Quote:

./units

where 'units' is the name of my binary. But I then get the output:

Quote:

units: can't find units file '/usr/local/share/units.dat'

...what? Why does it refer to that directory that's WAY out there? It seems like it's trying to outguess me on something? I don't know. Anyone out there that does? I'd appreciate an explanation, and help to know what to do to run this binary.

Ubuntu :: What To Do With An AMD64 Static Binary

Dec 14, 2010

I'm trying to use the software tool here, using the AMD64 static binary for no other reason than I am trying to install and use it on a 64 bit instance of MythBuntu.

[URL]

I figured I follow the instructions here

[URL]

But the 64bit version doesn't have a configure file. The only file in there is a .exe, that doesn't do anything when you double click it in a Linux file explorer, and I didn't know you even use .exes on Linux.

After lots of googling (very little information out there that isn't specific to a software package) it looks like maybe you skip the `configure` and `make`, and go straight to `make install`? Can I do checkinstall instead as recommended on the Ubuntu wiki? Or have I got this totally wrong? Is this unnecessary, and I should just use the regular source files on my 64 bit Mythbuntu install?
