The '#' in the Bash shell means that you are logged in as root. You never start Firefox as root, unless you like to have a compromised system.

To your command, you have to give a real display to the option, not just the word Display. If your Xserver is running on display :0 then you have to give that to the command, like

Code:

firefox -display=:0

@hitmen: Why do you have to run it as root? Anyway you could also do that if you ran X by startx as root instead of using a login manager (xdm, kdm, gdm, etc.).

e.g.

Code:

echo 'exec startkde' > ~/.xinitrc
startx

hi,

can you explain what this command do echo 'exec startkde' > ~/.xinitrc ?

SecretCode · 09-02-2012, 04:31 AM

It echoes the text "exec startkde" and redirects the output to the file "~/.xinitrc". So effectively it's editing the file .xinitrc and creating / replacing its contents with "exec startkde".

Well actually how do you know that you have to do this?
What linux certification you have to learn all this?
I have never dared to touch sys files in windows.

These are not system files more user config files they are in user home but they are hidden if you use gui to view files then control+h will show them or in terminal ls -a will show them.

Here is a good start to learn http://www.ee.surrey.ac.uk/Teaching/Unix/
chapter 3 looks at redirect to a file

If you google the file name it will discribe the file
