Software :: Writing A Script That Is Designed To Verify An Application Is Running?
Apr 13, 2010
I am writing a script that is designed to verify an application is running. The if...else statement in question is the following:
Code:
# Check if <application> is running.
ps -ef |grep <application> > /dev/null
RC=$?
echo $RC
[Code]....
I have started testing by disabling the application in question, and then running the script. The problem that I am seeing is that even though the application is not running, I am getting an output code of 0 due to the successful running of the ps command. What syntax change(s) do I need to make in order to accurately determine when the application is not running?

I'm trying to write a simple, console based application in linux, in c++. I know how to start in Eclipse and I have some experience in c++ from Windoze. I would like to ask, if there is some tutorial available on writing console apps. I mean, I know from using linux that there are two conventions on using parameters in command line (-v and --version for example).

I try to understand the way the network-admin tool retrieve and set information about the network connections, and after reviewing thee code, I still dont undertsnad how it does it. I thought that it should use maybe linux commands such as iwconfig or ifconfig or by using ioctl for get/set the parameters of the wireless, but I did not find such things in the code. It also does not use AT commands for modem devices parameters.
I see that it uses liboobs files, but after veiwing the code, I still don't understand how it works.
These question comes since I work on application which connects to wireless devices (possibly several wifi and modems devices can be connected ), and I try to think how to set/get the network parameters, I thought that a good start will be to look at how network-admin works.

I tried this command to print the buffer of an existing screen session to stdout but I don't know why it doesn't print anything.
screen -x lftp -X hardcopy /dev/fd/1
screen -x lftp -X hardcopy /dev/stdout
It works if I use a regular file instead, so why doesn't it print to stdout when I use /dev/fd/1? I do this with other applications don't have an option to write to stdout and it works, so what does GNU/Screen do that makes it not work?

Using CentOS 5.5. I have ssh setup to use a radius server for authentication. When I use filezilla to test sftp I can successfully authenticate and get directory listings, but every time I try to download or upload a file filezilla attempts to re-authenticate which fails because the radius server uses token auth with one time passwords, so the original password used to authenticate is no longer valid. However I can browse directories all I want and it never tries to re-authenticate.
1. is this re-auth just how sftp protocol was designed? like re-auth anytime a user tries a different action, like browse vs download vs upload?
2. or am I just missing something? (very likely, I'm not real experienced with linux)

If I was to set up a Cluster, I know it wouldn't make much difference to loading up my browser, but would all heavy duty programs (Video Encoders mainly) work with it, or would I need to use programs specifically designed for cluster use?

Which is why I'm glad KDE still values the good old desktop paradigm. I'd like to use unity, but unfortunately, it is impossible to customise in any significant fashion. I will be switching to Kubuntu now. I think a "start bar" is the perfect mouse & keyboard GUI paradigm.
My recomendation to the Ubuntu devs is to give unity an option to replace the awkward (for a mouse) application finder with a "start menu", and also give an option to have the old style of task bar as well.
I am not complaining here. like I said, I like KDE and have no problem switching over. The only reason I care about unity is; I don't want somebody to try Ubuntu, find out you can't customise the GUI at all, then go right back over to windows or OSX.

Does linux kernel 2.6 support suid & guid?. I just read somewhere that "latest linux kernels does not support suid & guid as it can pose a security risk if the setuid attribute is assigned to executable programs that are not carefully designed". I need a confirmation about what I say is correct or if not please correct me.

After a series of unrelated problems with my mouse (that had nothing to do with suse) I opened a process but I don't know what is it. It looks like a series of micro-post-its in the bottom of my desktop:Also, I checked the option to start a new session every time I start KDE, but this keeps appearing.

As the thread states, I wonder why my RAM usage is about 56% without any application running. It turns to 58% while opening Firefox (with only one Tab/Page opened) and typing this post. Is there something wrong?

I have two computers running Ubuntu. I want to run the copy of Firefox that is on the remote machine. i connect to the remote in the usual way, "ssh -X fermi", which brings up a console on the remote machine, fermi. When I type "firefox", however, it starts the copy of firefox that is on the local machine. On the remote machine, "ps aux|grep firefox" confirms that firefox is not running there. Is there a way to force execution of the remote copy?Or, can I start a local copy of firefox using the remote bookmarks, preferences, etc?

Running the Lynx and I have set up Evolution to download my Gmail e-mails but now I have a question.
When Evolution is running I get the notifications when e-mail come in and the little envelope at the top becomes "lit" to indicate I have new mail. What I want to know is how can I get notified without having the application "open", still having the notifications etc. but without having the application window open (like when you "close" Rhythmbox but it is still running at the top even though the windows is closed)?

I want to launch qiv upon startup to show a series of photos in slideshow fashion (this will be the sole purpose of this particular laptop). I tried adding the command via System->Preferences->Startup Applications but this does not produce the desired result. In fact, the slide show doesn't even start.

I have come across an issue. We have an application for the biotechnology. The application is very heavy so we are trying to run it on cluster. We have four Dell workstation 7500. Each is having 32 GB RAM. But I am not getting the exact method of configuring cluster and node. I have tried Conga (Luci, Ricci). My questions are:1) Is it possible that our application can run on cluster ?2) If its possible then how shall i configure it?

I frequently access my home computer throughout the day in two ways: either locally, or remotely using nxserver/nxclient. As one user, I have two concurrent X-windows sessions running, possibly with different applications running in each. Is it possible to move a running application from one session to the other? That is, I want all the active windows related to the app to disappear from one desktop,

I need to run an application on a virtual desktop (let say desktop #2) and control it via another app running on the root desktop (desktop #1). That would include screen capture and mouse movements. So basically I capture the application window from desktop #2, scrape it and then click on buttons via my app on desktop #1. Anyway you got the idea.Now my big question is: is that doable ? and if so what's the best language to do it ?
