Is it possible to have a main script (i will call it main.ksh) that executes say, 4 other scripts (sub_prog_1.ksh, sub_prog_2.ksh etc..) from within this main.ksh (simultaneously/in parallel), have them run in the background and communicate back to main.ksh when complete?
My guess is to use... (1 Reply)

Is there a way to monitor certain processes and if they hang too long to kill them, but certain scripts which are expected to take a long time to let them go?
Thank you

Hi
Is there an easy way to identify and group currently running processes into OS processes and APP processes. Not all applications are installed as packages.
Any free tools or scripts to do this?
Many thanks. (2 Replies)
Hi all,
I needed a little help. It's OS thing.
Suppose I have 2 machine connect over a network, I will call my machines as M1and M2.
If I copy a files from M1 to M2. What tasks are these two machine performing for copy to work.
My assumption is that M1 is performing read action and... (1 Reply)
I had issues with processes locking up. This script checks for processes and kills them if they are older than a certain time.
Its uses some functions you'll need to define or remove, like slog() which I use for logging, and is_running() which checks if this script is already running so you can... (0 Replies)

glutIdleFunc(3GLUT) GLUT glutIdleFunc(3GLUT)NAME
glutIdleFunc - sets the global idle callback.
SYNTAX
void glutIdleFunc(void (*func)(void));
ARGUMENTS
func The new idle callback function.
DESCRIPTION
glutIdleFunc sets the global idle callback to be func so a GLUT program can perform background processing tasks or continuous animation
when window system events are not being received. If enabled, the idle callback is continuously called when events are not being received.
The callback routine has no parameters. The current window and current menu will not be changed before the idle callback. Programs with
multiple windows and/or menus should explicitly set the current window and/or current menu and not rely on its current setting.
The amount of computation and rendering done in an idle callback should be minimized to avoid affecting the program's interactive response.
In general, not more than a single frame of rendering should be done in an idle callback.
Passing NULL to glutIdleFunc disables the generation of the idle callback.
EXAMPLE
A typical idle callback to animate a window might look like:
void
idle(void)
{
time += 0.05;
glutSetWindow(window);
glutPostRedisplay();
}
Notice how the idle callback does not do any actual drawing; it only advances the time scene state global variable. That is left to the
window's display callback which will be triggered by the call to glutPostRedisplay.
If you use the idle callback for animation, you should be sure to stop rendering when the window is not visible. This is easy to set up
with a visibility callback. For example:
void
visible(int vis)
{
if (vis == GLUT_VISIBLE)
glutIdleFunc(idle);
else
glutIdleFunc(NULL);
}
If you do use the idle callback for animation, one thing you should not do is setup the idle callback before calling glutMainLoop. It is
much better to use the visibility callback to install idle callback when the window first becomes visible on the screen.
