Hello everybody,
it would be of great help if you could provide me the entry of the default web browser in the linux file system. how can we access those entries of the default web browser and how can we launch that default web browser. thanks in advance.

Welcome to LQ.

Can you clarify what the browser has to do with the file system? I'm a bit confused by this.

Moved to Linux->General

The browser has nothing to do with the file system. It is just that I want to access the entry in the file system which shows that a paricular web browser ( for e.g. netscape, mozilla, galeon, konqueror, etc.. ) is the default one set for that particular system. It is so because I want to launch the particular default web browser on the system through code. So if I know where is the entry of the default web browser stored in the linux file system, I can access that entry in the file system and then launch the default web browser through code.
Thank You.

that isn't the way linux works. there are several user interfaces on the system, kde,
gnome and others, and the settings are specific to them. both kde and gnome have
sets of file associations in something called a control-panel, to make windows users
feel better. there aren't really system wide settings for a linux system like you are
hoping for. just kde-wide or gnome-wide, or others.

the settings you are thinking of are in a users home directory, in something similar
to .gnome or .kde

Perhaps the best option would be to run a script that checks for regular browsers being in the PATH:
mozilla
galeon
MozillaThunderbird
MozillaFirefox (I assume the case as I have't used it since the last name change)
opera
