View 1 Replies View RelatedI have a script that writes the following type lines to a file. The lines include some html tags. Here is an example:<p>Total = 5</h2></b></center>I want to keep the <p> tag, but remove the ending 3 tags. Sometimes the line can have a 1, 2, or perhaps a 3 digit Total. So I could have a Total = 125.Anyway, after the removal of the ending tags the result would be:<p>Total = 5There are some lines in the file that end with </h2></b></center> that I want to keep. These lines looks generally like this:
<p><b><center><h2>Events Summary for Sun May 02 2010</h2></center></b>
As you can see I am using sed to change the beginning and end of lines to make a very simple web page.The file actually displays ok in a browser with the extra tags on the end, but it is just sloppy work to have these unneeded tags in the output file.
I have several scripts in /etc/rcS.d/ directory which are required to run on start up.Now I have written a new script, and I want it to be run during the system start up itself (Not in any runlevel). SoI have given the default start as,# Default Start :SBut when I use the command : "update-rc.d test_script.sh defaults".....it is creating symbolic links to/etc/rc0.d /etc/rc1.d ..../etc/rc6.d.But I actually need a symbolic link in the /etc/rcS.d/ directory.Is there is any way to achieve this ( I tried manullay creating a link in /etc/rcS.d, but that is not running the script on system start up).

View 4 Replies View RelatedAnyway, here is something that is puzzling me and cannot think up a good way around it: I call the constructor and show elements of LoginDialog in the constructor of my QMainWindow, like this:
PHP Code:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow){ ui->setupUi(this); LoginDialog *lid = new LoginDialog(this); lid.show();}
LoginDialog is a QDialog and it does show up on application start... but...
It is not active! The QMainWindow is the active window, even if I put lid->activateWindow();
So, the question is: how do I pop up this dialog on application start in such a way that it will show the LoginDialog on startup as active window?

I'm trying to automate two command lines, a synclient and a syndaemon. They both work well if I type them manually in a terminal, but if I do a littre script to do this, tap to click and scrolling don't work anymore.
This is the script I wrote:
Code: Select all#!/bin/bash
synclient VertEdgeScroll=1
syndaemon -d -t -K
exit 0
So I made a chmod +x on the file, placed it in ~/bin then change PATH to include the directory. Then I added this file in "Startup applications".
The scripts run ok, mais it has a different effect than if I run the commands manually.
I was wanting to know what's a good programming suite that is comparable to MS Visual C++. I'm also curious about the portability of something I make in Linux, can I make a program in Linux and import it over to Windows, and what would be involved in making it compatible?

View 1 Replies View RelatedI am trying to develop a video resource manager in Linux.By that what I mean is, if two applications (may be running in two different machines) are trying to play videos, the video resources will be served by this video resource manager (running at a center location). Pardon me as I donot have much idea about video resource handling in Linux , first of all , it is feasible to have this kind of a layer, in between the applications and the available resource hardware.
Kindly give me some pointer as to how do I start? Pl. give me some reference URLs.

I need a start up script to execute AFTER my desktop loads. It's for display resolution. I've added the same script in 3 places, and all will execute, but not until I do it manually. It's being over-written by another function...

Can I create a run level 7, like rc7.d, that will execute after the desktop loads (and everything else)? I symlinked the second script to level 5 rd5.d, and it didn't go through. I haven't tried level 6.
